Listen to anything.
Articles, PDFs, books, messages, or any text you paste. ReadVoice reads it out loud in a natural voice and highlights every word as it goes, so it's easy to follow along.
Flip between the extension and the web app. Press play and it reads out loud, highlighting every word.
Ready
One for the web. One for everything else.
The browser extension
Reads the page you're already on.
News, blogs, documentation, email, an AI chat. Hover a paragraph and press play. Nothing to copy, nothing to upload.
See how it works →The web app
Reads anything you hand it.
Paste a message, a recipe, an essay. Drop in a PDF, an EPUB, a Word file. Or open one of the 10,000+ books already waiting there.
See how it works →More than a play button.
Follow the words as they're spoken, and take it at whatever pace suits the day. The rest, what you can bring it and what each product does with it, is below.
Follow along as you listen
An AI voice reads every word out loud while it lights up on the page, so you're seeing it and hearing it at the same moment. Two channels into your brain instead of one, so you catch more, lose your place less, and reading stops feeling like a fight.
The harbour had been quiet since the ferries stopped running, and the town had learned to live at the pace of the tide. Ólafur walked the length of the pier every morning, counting the boats that were left. There were nine, then seven, then five. He never said the number out loud, but he kept it the way other people keep a prayer.
Listen at your own pace
For a fast brain, reading is just too slow, so your attention wanders off. Speed it up and it matches your brain's tempo; suddenly reading moves as fast as you think, and there's nothing to drift from.
Listen to the web without leaving it.
It reads the page you already have open. No copying, no uploading, no second tab. Words light up as they're spoken, the page follows along, and a player you can put anywhere stays with you while you scroll.
-
1
A button in the margin
Hover any paragraph and it slides in beside it. Nothing to copy, nothing to upload. You start from the line you're looking at.
-
2
The word lights as it's spoken
The sentence is tinted and the single word being said is picked out inside it, on the page itself, not in a copy of it somewhere else.
-
3
The page keeps up with you
It scrolls itself so the spoken word stays on screen, including inside a chat's own scrolling column. Start scrolling yourself and it stops fighting you.
-
4
A player you can put anywhere
Drag it to whichever corner suits the page, or collapse it to a single orb. It remembers where you left it.
Six kinds of page, one play button
Four ways to start it
One click starts it: an article from the top, a chat from the model's latest reply. Click again to pause.
Hover any paragraph and it slides in beside it. On a chat, every reply keeps one permanently.
A Listen pill appears next to the selection. Or right-click and pick Listen to selection.
K plays and pauses, J and L jump ten seconds, < and > change speed. Ignored while you're typing.
One bar that belongs to you, not to the page.
It lives in its own shadow root, so no site's stylesheet can touch it, and it stays out of the way of a chat's composer instead of sitting on top of it.
- Drag it anywhere, or collapse it to a single orb. It remembers where you put it and how you left it.
- 67 voices, searchable by language. Change voice mid-article and it picks up from the sentence you were on, not the top.
- 0.5× to 4.5×, applied live, pitch intact. Ten seconds back and forward on either side of play.
- Light or dark, following the page it's sitting on.
It knows a chat when it sees one
ChatGPT, Claude, Gemini, Grok, DeepSeek and Kimi are matched by hand. When
those selectors break (and they do, since DeepSeek's message rows are
named _9663006 this week), a detector finds the conversation
from its layout alone, so a chat product we've never seen still gets a
button on every reply.
And what not to read
Reasoning panes, code listings, citation markers and the Copy/Retry chrome are all skipped. If a reply is still streaming it waits for it, rather than reading your own prompt back to you.
The page keeps up with you
It scrolls itself as it reads, so the word being spoken stays on screen, including inside a chat's own scrolling column, which isn't the window. Start scrolling yourself and it stops fighting you.
It tells you what went wrong
Server unreachable, signed out, nothing left to play: each one is a sentence in the player with the action that fixes it, not a silent button that does nothing when you press it.
Hand it anything. It opens as itself.
A file, a link, a photo of a page, a lecture recording, or text you pasted: six ways in, one library, and a reader that draws each one the way that kind of thing is meant to look.
- A file PDF, EPUB, Word, and four more
- A photo of a page Words lifted off the picture
- A link Fetched, stripped of clutter
- A video or recording Transcribed into timestamped chunks
- Pasted text No file, no length limit
- Your own voice Dictated, written out as you talk
One reader. Each thing still itself.
A photographed page keeps the photograph, with the words boxed where they sit on it. A document keeps the page it was printed on. A recording keeps its timestamps, and a link or something you pasted opens as a document like any other. Six ways in, three shapes on the page, one set of controls under all of them.
Six ways in
Everything under + New. If it has words in it, one of these takes it.
A file you've got
PDF, EPUB, Word, Markdown, HTML, RTF or plain text. Drop it straight onto the page.
A photo of a page
Snap the page of a real book and the words are lifted off the picture, then highlighted where they sit on the photo as it reads.
A link you can't face
Paste the address and ReadVoice fetches the page, strips the clutter and reads the article.
A video or a recording
A YouTube link, a lecture, a voice note. It's written out in short timestamped chunks you can search through instead of scrubbing back and forth.
Your own voice
Talk and watch it appear as you go. Useful when writing it down is the part that's hard.
Anything you paste
A message, an email, the small print. No length limit, and nothing to save first.
Everything lands in My Files
Whatever route it came in by, it's saved the moment it arrives and sorted by what it is, so the lecture you transcribed in March isn't lost among the PDFs.
- Five filters, one per kind. Documents, transcripts, scans, links and recordings.
- Folders you can rearrange. Make one, drag things into it, rename or move them later.
- Tidy up in one go. Select several at once and delete them together.
- It reopens where you left off, down to the sentence, and the next one starts playing on its own if you want it to.
Six kinds of thing, six ways of showing them
A document stays a document, with the words lit on the page where they are printed. A photo stays a photo. A transcript keeps its timestamps. One highlight, one set of controls, six surfaces.
- EPUB
- DOCX
- TXT
- MD
- HTML
- RTF
Seven formats, one category. A PDF is rendered as the real page with each word lit in place by its own rectangle. Click a word on the page and the audio jumps there. An EPUB keeps its running head and its chapters, a Word file its headings, a letter its date.
Straight into the reader, no file and no character cap. A whole chapter is as fine as a line.
The article as fetched, with the navigation, the pop-ups and the related-stories rail gone.
Paginated, in timestamped chunks with the time range on every one, so you can find the bit you needed.
Your photograph, with the words found on it boxed where they sit. The highlight tracks across the picture.
What you dictated, written out and read back, with the clip's own length on the bar.
Books are their own shelf: 10,000+ classics, chapters and all, see the library.
10,000+ classic books, free, ready to play.
Sherlock Holmes, Dracula, Pride and Prejudice, The Great Gatsby, sorted into 13 shelves. Tap a cover and chapter one starts. It remembers the chapter you were on, so you can pick it back up tomorrow.
Shakespeare · Detective & Mystery · Science Fiction · Horror & Gothic · Philosophy · Essential Novels · Adventure · Poetry · Biography · and four more
Not only in English.
Sixty-seven voices, spread across twenty-three languages. Whichever one you pick, everything else stays as it is: the words light up as they're spoken, at whatever speed suits you. Below is the word listen, in each of them.

Most languages come with both a male and a female voice, and three of them come in more than one accent: English in British and American, Spanish in European and Mexican, Dutch in Netherlandic and Flemish. The picker searches by language, and changing voice halfway through carries on from the same word.
Set it up the way your eyes want it.
There's no single colour or typeface that helps everyone read more easily, so all of it is yours to change. The swatches and typefaces on the demo above are the real ones; try them and see what feels better.
Typefaces that help
Five to choose from, including OpenDyslexic and Atkinson Hyperlegible, the latter drawn for low vision, and used for every word on this page.
Pick your highlight colour
Soft green, soft blue, rose or warm orange. Whichever you choose, the word being read stays sharply legible against it.
Any speed, still human
Slow it to 0.5× to follow closely, or push to 4.5× to get through a chapter. The voice keeps its pitch. No chipmunk.
23 languages, 67 voices
English, Spanish, French, Italian, Portuguese, Hindi, Japanese, Mandarin, German, Dutch, Polish, Swedish, Icelandic and a dozen more.
Voices you can swap
Change voice in the middle of a sentence and it carries on from the same word in the new one.
A gentle nudge
Set a daily listening goal and ReadVoice keeps a quiet count of how much you got through this week.
Anything else?
What is ReadVoice?
ReadVoice is a read-aloud app and browser extension that turns anything you read into speech and lights up every word as it is spoken, so it is easy to follow along. It reads articles, PDFs, ebooks, Word files, photos of printed pages, recordings and anything you paste, in 67 voices across 23 languages.
What is text to speech (TTS)?
Text to speech, also called TTS or read aloud, is turning written text into spoken audio with an AI voice. ReadVoice is a text to speech reader: give it text in any form and it speaks it back to you, highlighting each word as it goes.
What is an AI voice?
An AI voice is speech generated by a model rather than recorded by a person, which is what lets any text be read out loud on demand. ReadVoice's 67 AI voices keep their pitch at every speed, so nothing sounds sped up or robotic.
Who is ReadVoice for?
Anyone who takes information in more easily by listening: students, professionals, and readers with dyslexia or ADHD. It was built by someone with both.
How can I use ReadVoice?
Open the web app in your browser and start listening straight away, with nothing to install. Add the Chrome extension as well and you can press play on any page you are already reading.
Is ReadVoice free?
Yes. Every voice, every language, the whole book library and every way of getting text in are free with an account. There is no card to enter and no monthly limit on how much you listen to.
Do I need an account?
To listen to your own documents, yes: an email address and a password. Every demo on this page plays without one, so you can hear the engine before you decide.
What devices does ReadVoice work on?
ReadVoice runs in the browser on Windows, Mac, Linux and ChromeOS, and the extension works on any site you open in Chrome. Desktop and mobile apps are in the works.
How do I add content to ReadVoice?
Drop in a file, paste a link, paste text straight in, photograph a printed page, record yourself talking, or open one of the built-in books. Six ways in, and everything lands in the same library.
What file formats does ReadVoice support?
PDF, EPUB, DOCX, RTF, HTML, TXT and Markdown files up to 50 MB each, plus web links, photos of pages, audio and video files, and text you paste.
Can ReadVoice read PDFs?
Yes. A PDF opens as the real page, with headings, figures and page furniture where they belong, and each word lit in place by its own rectangle. Click a word on the page and the audio jumps straight to it.
Can ReadVoice scan text from a photo?
Yes. Photograph or upload a page of a real book and ReadVoice lifts the words off the picture with OCR, then highlights each one where it sits on the photo as it reads.
Can ReadVoice read YouTube videos?
Yes. Paste a link and ReadVoice writes out what is said, split into short timestamped sections you can read along with or skim. The same works for an audio or video file off your own computer.
Does ReadVoice work on AI chats?
Yes. The extension puts a play button on every reply in ChatGPT, Claude, Gemini, Grok, DeepSeek and Kimi, and recognises a conversation from its layout alone, so chat products it has never seen still get a button.
Does ReadVoice include books?
Yes. 10,000+ public domain classics are already in the library, chapters and all, sorted into 13 shelves. Tap a cover and chapter one starts, and it remembers the chapter you were on.
Can ReadVoice read something really long?
Yes, there is no character cap, so paste a whole book if you like. Long documents start playing within a few seconds and keep preparing the rest while you listen, so you are never sat waiting for a progress bar.
Do ReadVoice voices sound natural?
Yes. Press play on any demo on this page: that is the engine itself, unedited, including the way the highlight lands on each word. Every voice keeps its pitch when you speed it up.
How many voices does ReadVoice offer?
67 voices across 23 languages, most of them with both a male and a female voice, and you can change voice halfway through a document without losing your place.
What languages does ReadVoice support?
Twenty-three: English, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Swedish, Ukrainian, Greek, Icelandic, Hindi, Japanese, Mandarin, Persian, Kazakh, Latvian, Nepali, Slovenian, Telugu, Urdu and Vietnamese.
What accents does ReadVoice offer?
English comes in British and American, Spanish in European and Mexican, and Dutch in Netherlandic and Flemish. The picker searches by language, so the accent you want is one tap away.
Does ReadVoice highlight words as it reads?
Yes. The sentence being read is tinted and the single word being spoken is picked out inside it, on the page itself rather than in a copy of it somewhere else.
Can I change the reading speed?
Yes, anywhere from 0.5x to 4.5x, and the voice keeps its pitch the whole way up. Speed changes apply as it plays, so you can find your pace without restarting.
Can I change how the page looks?
Yes. Five typefaces including OpenDyslexic and Atkinson Hyperlegible, four highlight colours, and text size and line spacing of your own choosing.
Does ReadVoice help with dyslexia and ADHD?
Plenty of people find that hearing text while watching the words light up makes it far easier to stay with, and that is who this was built for. It isn't a medical device and we won't pretend it's a treatment, but the fonts, colours, speeds and highlighting are all here to be adjusted until reading stops being a fight.
Where do my documents go?
They stay in your browser, on your own machine, rather than in a library on our side. Text is sent to the server for the one job only it can do, turning it into speech, and it isn't kept afterwards.
