94 answers across 12 topics: what each Toolvoy tool does, the limits it works within, how your files and text are handled, and what to do when something goes wrong.
Toolvoy is a free collection of small online tools for jobs that come up every day: counting words, checking grammar, generating keyword ideas, merging PDFs, resizing images, formatting JSON, building a mailto link and more.
Every tool has its own page with instructions, examples and its own limits spelled out. Most of them work the same way: you paste, type or drop something in, the result appears, and you copy or download it.
Yes. There is no trial period, no credit balance, no account tier and no watermark on results. No tool has a paid version that unlocks extra options.
There is advertising space reserved in the layout, but no advertising is switched on at the moment. If ads are ever enabled, they will not change what a tool does or how it behaves.
No. There is no registration and no sign-up form. Open a tool page and start using it, or open several at once in different tabs.
Saved favourites are kept in your own browser rather than on an account, so they need no login either.
Yes. Every page and tool is built to work on phones, tablets, laptops and desktops, and the inputs, tables and download buttons resize to fit the screen.
PDF and image work happens on your device, so a very large file may be slower on an older phone than on a desktop. That is a memory limit in the device, not a restriction in the tool.
They work in current versions of Chrome, Edge, Firefox and Safari on desktop and mobile.
A few tools lean on newer browser features, so an old or unusual browser may refuse one of them: PDF preview and export, image canvas export, and the text-to-speech voice list are the three most likely to differ. All of the browser tools are designed to run without any extension being installed.
Yes, and there is no limit on how many you open. Each tool is independent, so a PDF in one tab and a keyword list in another do not interfere with each other.
Nothing carries over between tools: a tool is designed to do one job, and its inputs reset when you leave or reload the page.
There is no daily quota, no request counter and no throttling of the browser tools. What you will meet are technical limits, and each one is shown in the tool before you reach it.
Examples: images up to 20 MB, PDFs up to 25 MB and 500 pages, share-room files up to 5 MB each, and rooms that accept up to 40 items. Site-wide tools like the sitemap generators need your website to be publicly reachable so it can be read.
Tools are added and refined continuously. There is no public changelog, so the page you are reading is always the current description of what a tool does, including its limits.
If a description and a tool ever disagree, treat the page as the older of the two and report it — that is a bug worth fixing.
Use the contact form and choose “Report a problem”. Include the tool name, what you did, what you expected and what happened, plus your browser if you know it. The values you entered are useful, as long as they are not confidential.
You can also write to contact@toolvoy.com directly. Reported bugs are read, but no reply time or fix date can be promised.
Use the contact form and choose “Tool suggestion”. Describe the job you need done, the input you would give it and the result you would expect. Examples help more than tool names.
Suggestions are read and weighed against the existing collection, but there is no schedule or obligation to build a specific request.
Not all of them. Your browser downloads the page the first time you open it, and then the tools that process things locally keep working even if the connection drops mid-way.
The handful of tools that read a website you name — the XML sitemap generator, the HTML sitemap generator and the sitemap validator when you give it an address — need a connection, because the pages have to be fetched before they can be checked.
No. Toolvoy currently offers no accounts at all: no sign-up, no login and no password to remember. Every public tool is open to anonymous visitors.
That is a deliberate design choice rather than a missing feature — it means there is no profile to fill in, no email to verify and nothing about your use of the tools stored against your name.
Favourites are stored in your own browser’s local storage for this site, on this device only. Nothing is sent to a server and no account is created by saving one.
Because of that, favourites do not follow you to another browser, another device or a private window, and clearing site data removes them. The favourites page only shows slugs of tools that still exist, so an old entry can never turn into a broken link.

There is no account sync today. To keep a link handy on a second device, either bookmark the tool page itself or open it by its address on the other device.
For moving a piece of work rather than a tool link, the Share feature creates a temporary room with a short code you can open on another device — that is a hand-off, not a permanent sync.
Because visitors do not need one. The only sign-in on the site belongs to Toolvoy’s own content administration, used by the site’s maintainers to publish blog articles.
It is not part of the public product, offers nothing to visitors and is not linked from the navigation.
You give it one seed keyword. It then builds variants from the way people actually phrase searches: word order changes, plurals, question forms, comparisons, modifiers and long-tail additions. The ideas are grouped so you can scan them by type.
It is a language-pattern generator, not a search index. There are no search volumes, difficulty scores or ranking data behind the results, because Toolvoy has no paid keyword database. Treat the list as a starting point to research further.
Related: Keyword Generator
No. Search volume comes from paid data providers, and Toolvoy does not license one. Any volume or difficulty number you see here would have to be invented, so none is shown.
What the keyword tools do give you is breadth and structure — related phrases, long-tail variants, questions and groups — which you can then check in whichever keyword tool you already use.

Keyword density is how much of a piece of text is taken up by one word or phrase, as a share of the total words. The Keyword Density Checker shows single-word counts, phrase counts and the resulting percentages.
There is no target percentage worth chasing. Use it to catch accidental repetition — a term that keeps reappearing because the writing is thin — rather than to hit a number. Search engines do not publish a density threshold.
Related: Keyword Density Checker
The Keyword Clustering Tool compares your phrases by the significant words they share. Phrases that overlap enough land in the same cluster, and each cluster shows the shared terms that caused the grouping.
The rule is deliberately transparent: you can read why two phrases were grouped. It is word overlap rather than a semantic model, so synonyms written differently stay apart, and you should rename or merge clusters by hand where the grouping is not useful.

The XML Sitemap Validator accepts the file three ways: paste the XML, upload the file, or give it the address the sitemap lives at. It then checks the XML syntax, the sitemap namespace, the URL entries, the lastmod dates and the structure of a sitemap index.
Duplicate entries and live addresses are checked separately, so a structurally valid sitemap can still show warnings. Loading from an address needs a working connection, since the file has to be fetched first.
Related: XML Sitemap Validator
An XML sitemap is a machine-readable file, usually at /sitemap.xml, that lists your URLs for search engines and is submitted through their webmaster tools. An HTML sitemap is a normal page for people, listing your links so a visitor can navigate the whole site.
Toolvoy has a generator for each. Both can discover your pages from one website address; the XML one produces files plus an index, and the HTML one produces a page you can publish and preview.
Related: XML Sitemap Generator · HTML Sitemap Generator
You paste the content of your robots.txt file. The validator checks it line by line, explains every directive in plain English, flags malformed lines and unknown directives, and points out rules that are likely to block crawlers you want.
It does not fetch your live file from the web. That is deliberate: it means you can test a draft before you upload it, without the result depending on caching or DNS.
Related: Robots.txt Validator
You enter your website address once. The generator starts from your existing sitemap if there is one, and otherwise follows internal links, collecting the pages it can reach. It then writes a sitemap.xml you can download, splitting into several files with an index once a file would exceed 50,000 URLs.
It can only list pages it can actually reach: a site that blocks automated requests, or one whose navigation is built entirely by JavaScript after the first load, will come back with fewer pages than you expect.
Related: XML Sitemap Generator
Because of the browser’s cross-origin rules. A page cannot read the source of another website directly, so no browser-only tool can look inside a page you name. Rather than pretend, the checker asks you for the source: open the page, view its source, copy it and paste it in.
It then reports the title, description, heading order, image alt text, link counts and the robots and sitemap references it finds in that HTML — the same things you would otherwise check by hand.
Related: Website SEO Checker
No, and it would be dishonest to claim otherwise. Ranking depends on factors no browser-based tool can see: the full index, competitor pages, links, and the site’s history.
What the SEO tools can do is fix the mechanical part — is the title a sensible length, are the headings in order, is the sitemap valid, is robots.txt blocking anything it should not, is the keyword actually used in the copy. Those are the checks worth doing first.

As a working guide, keep titles roughly within 50 to 60 characters and descriptions within about 150 to 160. Search results cut off anything longer, so the end of your message is lost rather than shown.
The Meta Title Generator and Meta Description Generator both give you editable drafts with a live character count, so you can judge the cut-off instead of guessing. Neither one predicts ranking — the length is about being read.
Related: Meta Title Generator · Meta Description Generator
Yes. The SERP Snippet Preview shows a title, URL and description as a search listing and estimates the pixel width at desktop and mobile sizes.
Pixel width is the useful part: a title can fit in 55 characters of narrow letters and overflow in wide ones. If the preview truncates, shorten the title rather than adding keywords.
Related: SERP Snippet Preview
The Open Graph Preview shows the title, description, image and URL as a social card, then gives you the matching Open Graph and Twitter Card meta tags to copy into your page.
The tags are what other sites read, so checking them here before publishing is faster than posting the link somewhere and deleting it afterwards.
Related: Open Graph Preview
The Search Intent Classifier labels each keyword as informational, navigational, commercial or transactional, using the wording of the phrase itself — question words, comparison terms, buying words and brand names.
Each label shows the signal that produced it, so you can disagree with the tool. Intent decides what kind of page would satisfy the search, which matters more than the exact phrase.
Related: Search Intent Classifier
The SEO Content Brief Generator turns a topic, an audience and your keywords into a structured brief: an intent hypothesis, suggested headings, subtopics, the questions the page should answer and an outline you can write against.
It organises your own input rather than researching the topic for you, so the brief is a scaffold — fill it with substance before publishing.
Related: SEO Content Brief Generator
Yes — the Word Counter updates as you type and shows words, characters, sentences and paragraphs, plus estimates for reading time and speaking time.
Separate tools go deeper when you need them: the Sentence Counter and Paragraph Counter list each sentence or paragraph with its length, and the Word Frequency Counter totals how often every word appears.

Yes. Every writing and text tool runs on rules and formulas inside your browser. Nothing you paste is sent anywhere, which is why the tools can be used on drafts and internal documents.
The trade-off is that the checks are the ones written into the code. Each tool page says what its rules look for, so you always know why something was flagged.
Related: Grammar Checker
No. It runs a fixed set of checks: repeated words, spacing and punctuation mistakes, missing capital letters and a list of common misspellings. Anything it flags has a specific rule behind it, and you can copy a corrected version.
That also means it will not restyle a sentence or catch an error that needs context to notice. It complements careful reading; it does not replace it.
Related: Grammar Checker
You paste a passage and choose one of three strength levels. The tool substitutes words from a built-in list while keeping your sentence structure and meaning intact, so you can see exactly what changed.
Because the substitutions come from a fixed list, an unusual word may be left alone and a common one may be swapped for something slightly less apt. Read the result before you use it — the tool is a fast first pass, not a finished rewrite.
Related: Paraphrasing Tool · Text Rewriter
No. The Text Summarizer is extractive: it scores your own sentences and keeps the most representative ones, either as a short summary or a longer one.
Nothing is invented and no wording is generated, so a summary reads like your text, shortened. If a key idea only exists implicitly, it will not appear in the summary.
Related: Text Summarizer
The Readability Checker scores a passage with the Flesch Reading Ease formula, then shows average sentence and word length and lists the hardest sentences so you can fix the worst ones first.
The formulas are calibrated for English, so treat the score as a guide rather than a verdict — and remember it describes how easy the text is to read, not how good it is.
Related: Readability Checker
Use the Duplicate Sentence Checker: it finds sentences that appear more than once and shows exactly where each repeat sits, so you can decide which copy to keep.
That is different from the Text Cleaner, which removes extra spaces, blank lines and duplicate lines, and from the Text Formatting Helper, which fixes pasted text in stackable steps such as collapsing spaces, unwrapping line breaks or stripping HTML tags.

Yes. The Text to Speech tool uses the voices already installed on your device through your browser, with speed and pitch controls and play, pause and stop buttons.
Two honest limits: there is no audio file to download, because the speech is generated by your device rather than recorded, and the available voices depend on your operating system and browser. A device with no voices installed will stay silent.
Related: Text to Speech
Yes. The Text Comparison tool shows what was added and what was removed between two versions, either line by line or word by word.
It is the quickest way to check what actually changed after an edit, and it works on pasted text rather than on files.
Related: Text Comparison
No, and the tool says so itself. The Paragraph Generator produces template-based sample paragraphs for layouts, mockups and drafts — not researched copy and not AI output.
Use it as placeholder text where the shape of a paragraph matters. The Lorem Ipsum Generator does the same job in the traditional dummy-text style.

The Case Converter switches pasted text between UPPERCASE, lowercase, Title Case and sentence case in one click, and you copy the result.
It is the quick fix for a heading pasted in capitals or a paragraph that arrived in title case from a word processor. It changes case only — it does not fix grammar or wording.
Related: Case Converter
Yes. The Sentence Rewriter tidies one sentence and shows alternative wordings built from your own words, so you can compare options before copying the one that reads best.
Use it when only one line is clumsy. For a whole passage, the paraphrasing tool keeps the structure and works across the full text.
Related: Sentence Rewriter
Yes. The Word Frequency Counter counts how often every word appears, can hide common words such as “the” and “and”, and exports the full list as a CSV file you can open in any spreadsheet.
That is the practical way to audit a long document for overused words, or to start a glossary from your own copy.

PNG, JPEG and WebP — both as input and as output — up to 20 MB per image.
Formats such as GIF, SVG and HEIC are not handled by the image tools. If you have a photo from an iPhone in HEIC, convert it on the device first, then use the tools.
Related: Image Converter
Making an image smaller always discards pixels, and they cannot be recovered — but for screen use the result usually looks identical. The Image Resizer lets you set the width and height and keeps the proportions when you change one side.
Making an image larger cannot add detail that was never there; it will look soft. PNG output stays lossless, while JPEG and WebP are compressed, so keep the original if you may need it again.
Related: Image Resizer
Open the Image Converter, drop in a PNG, JPEG or WebP file, choose the output format and download the result.
Transparency survives a conversion between PNG and WebP because both support an alpha channel. JPEG has no transparency at all, so transparent areas cannot survive that direction — pick PNG or WebP if you need them.
Related: Image Converter
The Image Compressor gives you two controls: a quality slider and an optional maximum width. Lower quality means a smaller file, and reducing the width removes pixels as well.
If your file is a PNG, the quality slider does nothing — PNG is lossless, so the tool says so. For a big PNG the usual answer is to resize it, or to convert it to WebP or JPEG, which compress much better.
Related: Image Compressor
No. Images are opened and re-encoded inside your browser using the canvas API, so the file never leaves your device. Nothing is stored by Toolvoy and nothing has to be cleaned up afterwards.
That also explains the practical limit: a very large image needs enough memory on your device, so an older phone may struggle where a desktop does not.
Related: Image Compressor · Image Resizer
Yes. The QR Code Generator turns a link or any piece of text into a QR code and lets you download it as a PNG image or as an SVG, which stays sharp at any printed size.
The code is generated in your browser, so the address you encode is not sent anywhere. Test it with a phone before you print it at scale.
Related: QR Code Generator
Yes. Choose two or more PDF files, set the order you want them in, and the Merge PDF tool writes one combined document you can download.
Files are processed on your device, so there is no upload step and no queue. Each file has to be within the tool’s limits: up to 25 MB and up to 500 pages.
Related: Merge PDF
Yes. The Split PDF tool takes ranges such as 1-3, 4, 5-8 and produces a separate file for each part, which you then download individually.
Splitting by explicit ranges is more predictable than splitting by page count, because you decide exactly where each new document starts and ends.
Related: Split PDF
No. Merging, splitting, rotating, image-to-PDF conversion and editing all happen inside your browser, so the document stays on your device.
This is the reason the PDF tools can be used on contracts and invoices at all. The limits you meet — 25 MB and 500 pages — come from what a browser can hold in memory, not from a server quota.
Related: Merge PDF
No, and no browser tool can do it reliably. The PDF Editor works as a layer on top of your pages: the text you type, highlights, shapes, drawings, images and signatures are stored as new content, while the original page content is copied through untouched.
That makes it the right tool for filling in a form, annotating, signing, adding a watermark or page numbers, and rearranging pages — and the wrong tool for rewriting a sentence that is already printed in the file.
Related: PDF Editor
The editor’s built-in fonts cover Latin characters. Text in other scripts may not render correctly, so check the exported file before you rely on it.
This is a real limitation rather than a setting you have missed. For scripts outside that range, add the text in a full desktop editor that embeds the required font.
Related: PDF Editor
Yes. The Images to PDF tool takes JPEG and PNG images, keeps the order you arrange them in, and builds one PDF — either sized to each image or centred on A4 pages with a margin.
Choose “sized to each image” for a photo set, and A4 for anything that needs to print or attach cleanly to other documents.
Related: Images to PDF
The most common reasons are a password or permission setting that stops the file being read, a download that was cut short, and a file that is larger than 25 MB or longer than 500 pages.
Try opening the file in a PDF viewer first: if it prompts for a password there, the tool cannot open it either. Re-downloading a truncated file is often all that is needed.
Related: Merge PDF
Yes. The Rotate PDF tool turns all pages, or only the page numbers you list, by 90, 180 or 270 degrees and saves the corrected file.
Listing specific pages is the useful part: a scanned batch often has only a few sideways pages, and rotating the whole document would leave you with a different problem.

JSON (format, minify and validate), plain text for Base64, URLs and URL components, and UUID version 4 values.
There is no JavaScript, CSS, HTML or SQL formatter here, and nothing in the collection runs, executes or parses code. The developer tools are deliberately narrow, which is why each one can explain its own output.
Related: JSON Formatter
Yes. Paste your JSON into the JSON Formatter: valid input is formatted with indentation, and invalid input is rejected with the line and column of the problem.
Pointing at the position rather than just saying “invalid” is the whole point — a trailing comma or an unquoted key is easy to find once you know where to look.
Related: JSON Formatter
The JSON Formatter does both for JSON: format adds indentation so the structure is readable, minify strips the optional whitespace so the payload is as small as possible.
Nothing is sent to a server, so it is safe for configuration files and API responses you would rather not paste into an online service you do not know.
Related: JSON Formatter
Yes. The Base64 Encoder and Decoder works on UTF-8 text, so accented letters, Cyrillic, Arabic, Chinese and emoji survive a round trip.
One thing worth remembering: Base64 is an encoding, not encryption. Anyone can decode it, so never use it to hide a password or a key.
Related: Base64 Encoder / Decoder
They are UUID version 4 values built from your browser’s cryptographic random generator, so they are suitable as identifiers in databases, APIs and test data. You can generate one at a time or a whole batch.
Treat them as identifiers, not as secrets: a UUID is unique, but knowing one tells you nothing about the next. It will not work as a password or an access token.
Related: UUID Generator
The URL Encoder and Decoder converts spaces, ampersands, slashes and non-English characters into the percent-encoded form a URL needs, and turns that form back into readable text.
You can encode a single parameter value or a complete URL, and invalid input is reported with a clear error instead of a half-decoded result.
Related: URL Encoder / Decoder
Fill in your name, role, company and contact details, pick one of the built-in styles, and the tool builds a plain, table-based signature with inline styling — the kind that survives being pasted into a mail client.
You then copy it as rich text straight into the signature settings of Gmail, Outlook or Apple Mail, or download it as an HTML file and use that. Test it by sending yourself one message before you roll it out to a team.
Related: Email Signature Generator
The Mailto Link Builder takes recipients, CC and BCC addresses, a subject and a body, then produces one correctly encoded mailto link plus an HTML snippet you can drop into a page or a button.
Encoding is the fiddly part it handles for you: spaces, ampersands, question marks and line breaks in a subject or body all have to be escaped or the link breaks. Keep in mind that a mailto link opens the visitor’s own mail app, and some apps limit how long a single link can be.
Related: Mailto Link Builder
Paste a block of text and the Email Extractor pulls out every address it recognises, merges duplicates and shows how many domains were found. You can copy the cleaned list or download it as a text file.
It does not check whether an address is real, deliverable or still active — that needs sending mail. And it is still your responsibility to have a lawful basis for mailing the people on that list.
Related: Email Extractor
No. The email tools build markup and links; they never send anything on your behalf, and there is no mail server behind them. Delivery still happens in your own mail client or platform.
The one place you can send something to Toolvoy is the contact form, which stores the message you write for review.
Three common questions: what a percentage of a number is, the percentage increase or decrease from one number to another, and the percentage difference between two values.
It shows the working as well as the answer, so you can see which formula produced the result rather than trusting a black box.
Related: Percentage Calculator
Length, weight, temperature, area, volume, speed and time. You pick a unit and a value and it converts to the others in that family as you type.
Temperature is the one family that is not a simple multiplication, which is why it needs its own offset — the tool handles that rather than scaling the number.
Related: Unit Converter
The Age Calculator gives an exact age in years, months and days between two dates, plus the total number of days lived and the date of the next birthday.
It counts calendar days rather than approximating with 365-day years, so leap years and different month lengths are handled correctly.
Related: Age Calculator
Yes. Set the starting amount, the interest rate, the term and any regular contribution, and it projects the balance with a year-by-year table and a growth chart.
The projection assumes the rate stays exactly constant for the whole term, which no real account does. Treat the result as a model of what compounding does over time, not as financial advice.

Open the Share page, choose how long the room should live, and you get a link plus an eight-character code. Open that link on the other device, or enter the code, and you see the same room.
Inside the room you can add text, links and files, and everything you add appears for anyone who has the link while the room is still alive.
You choose the lifetime when you create it: 15 minutes, 30 minutes, 1 hour, 6 hours, 12 hours, 24 hours or 48 hours. 48 hours is the maximum.
The room page shows a live countdown, so it is clear how much time is left before anything in it disappears.
Yes. No account is needed, for you or for the person receiving the code.
The limits are: up to 40 items per room, text up to 20,000 characters, and files up to 5 MB each in these formats — pdf, png, jpg, jpeg, webp, gif, txt, csv, md, json, zip, docx and xlsx.
The room and everything in it — text, links and files — is deleted. The link stops working and file downloads stop working with it, because downloads are served through short-lived links that expire on their own.
Expired rooms are cleared the next time the feature is used, so a room is never kept around as an archive. There is no way to recover one afterwards.
Yes. From the open room you can remove a single item or delete the whole room, which takes every item in it with it.
Anyone holding the room link can do the same, because there are no accounts to attach permissions to. That is the trade-off for not asking anyone to sign up.
Treat it as a hand-off, not a vault. The code or link is the only key: anyone who has it can open the room while it exists, and there is no password on top of it.
Content lives on the server for the lifetime you chose and is then deleted. Because the code is the only protection, avoid putting passwords, keys or confidential documents in a room; use a password manager or an encrypted archive instead.
For the browser tools, no. The text you count, the PDFs you merge or edit, the images you resize and the JSON you format are all handled by your own device, and nothing is sent to Toolvoy.
The exceptions are explicit and few: the contact form stores what you submit, share rooms store what you deliberately put in them, and the website-reading SEO tools fetch the address you give them because the pages have to be read from the web.
Four things, and nothing else: the details you type into the contact form; the content you add to a share room; the website address you give a sitemap tool; and anonymous usage counts — which tool was opened, whether a run finished, how long it took, and a random per-session id.
The usage counts never include the text, numbers, file names or files you put into a tool. There is no account, so no profile is built from them.
There are no advertising or tracking scripts on the site, and no advertising is active — the reserved ad spaces stay empty until a publisher account is configured.
Your browser does hold two kinds of local data: your favourites and recently used tools, stored on your device only, and a random session id used to group the anonymous usage counts. Clearing site data removes both.
Everything the site serves is delivered over HTTPS, so the address you visit and any form you submit travel encrypted.
Beyond that, the honest answer is that you should judge each feature by what it stores: the browser tools store nothing, share rooms store their content only for the lifetime you chose and then delete it, and the contact form keeps the message so it can be answered.
For the tools that work locally — PDF merging and editing, image resizing, text and JSON processing — yes, in the sense that the file never leaves your device. That is what makes them usable on contracts and internal notes.
Do not put confidential material into a share room, since the code is the only thing protecting it. For sensitive files, an encrypted archive plus your own transport is the safer route.

For the browser tools, nothing is transmitted, so the usual concern about pasting into an unknown website does not apply in the same way. The data still exists in the page while it is open, so close the tab when you are done with something sensitive.
For the site-reading SEO tools, the address you enter is fetched by the server — never paste internal or staging addresses unless you are happy for them to be requested from the internet.
Check that the input is something the tool can actually use: the field filled, the file in a supported format, the value inside the allowed range. Each tool shows a specific message when it rejects something rather than failing silently.
If the message does not explain it, reload the page and try again in a second browser. A stale cached bundle is the most common cause of a tool that suddenly stops responding after an update.
Almost always a size or format limit. Images are accepted up to 20 MB as PNG, JPEG or WebP; PDFs up to 25 MB and 500 pages; share-room files up to 5 MB each and only in the listed formats.
The rejection message states the actual size and the limit, so you can see which one you hit. Splitting a large PDF, or resizing an image before uploading it to a share room, usually solves it.
Browsers block or queue multiple downloads from one page, so tools that produce several files — split ranges, for example — are the usual place this shows up. Allow downloads for this site and take the files one at a time.
On iOS, a download may land in the Files app rather than in a visible folder. Check there before assuming nothing happened.
Copying to the clipboard needs a permission that some browsers only grant on a secure connection or after an explicit click. Try the button again directly, and make sure the page is loaded over HTTPS.
If it still refuses, select the result by hand and copy it — every tool also shows its output as plain, selectable text for exactly this reason.
It can only list pages it can reach from the address you gave it. If your robots.txt blocks automated requests, if the server is slow or offline, or if the navigation is built by JavaScript after the first load, some pages will be missed.
Check that your sitemap.xml is reachable and lists what you expect, and that robots.txt does not block the crawler. Where discovery still falls short, the pasted-HTML checks can cover the individual pages you care about.

The tool uses the voices installed on your device, so silence usually means the device has none, or the browser has not been allowed to start audio yet. Press play again after interacting with the page, and check your system volume and output device.
Voice lists differ a lot between macOS, Windows, Android and iOS. If the list is empty, install a system voice in your operating system settings — and remember there is no audio file to download, because the speech is generated live.

Rooms are deleted the moment their lifetime runs out, and that is not reversible — create a new room and share the fresh link instead.
Codes are eight characters and use capital letters and digits. If a code is being rejected, it was probably mistyped or came from a room that has already expired rather than from a bug.
A hard reload fixes most of these: press Ctrl+F5 on Windows, or Cmd+Shift+R on a Mac, to fetch the current version instead of the cached one.
If it survives a reload in a second browser too, it is worth reporting — include the page address and what you see, and it can be fixed for everyone rather than worked around.
None of the 54 tools sends your text or files to an AI model. The writing tools run rules, substitutions and formulas; the SEO tools build keyword variants from language patterns; the summariser picks your own sentences; the paragraph generator fills a template.
Where a result is an estimate or a template, the tool page says so. If a tool that relies on an external service is ever added, its page will name that service before you use it.
The output of the tools is yours to use. There is no licence fee, no attribution requirement and no watermark to remove.
The material you put in is another matter: make sure you have the right to reuse the text, images and PDFs that you run through a tool, and treat placeholder copy from the lorem ipsum or paragraph generators as filler to be replaced before publication.
Yes. Every tool has a permanent address of the form /tools/tool-name, so you can bookmark it or link to it from a page without worrying that it will change.
You can also save a tool with the favourite button on its card, which keeps it in your browser and adds it to the favourites page — no account needed. Results themselves are not stored, so a link to a tool never exposes what you typed into it.
