About this extension
Listen to any web page, PDF or e-book with natural-sounding voices — free, with no account. Readwell reads the article (not the menus and ads), highlights each word as it is spoken, and keeps playing while you browse.

Natural voices, free
300+ lifelike neural voices in 140+ languages and accents. No sign-in, no subscription, no monthly limit. A French page gets a French voice automatically, and your choices are remembered per language.

Follow along
The sentence and the word being read light up on the page, and the page scrolls with the voice. Alt+click any paragraph to jump there, or right-click → "Read aloud from here". Select text first to read just that part.

Keeps playing
A small player sits on the page (play, pause, skip, speed). Close the tab and it keeps reading; "Show text" in the toolbar brings the text back where you were.

PDFs, e-books and documents
Reader view opens PDF, EPUB, Kindle (MOBI, AZW3, PRC — DRM-free), Word (.docx, .doc), OpenDocument, PowerPoint, Excel, FB2, RTF, HTML, Markdown and text files, a link to a document, or anything you paste. It has a contents sidebar (chapters, PDF bookmarks, pages), light/sepia/dark themes, an easy-reading font, and a library that remembers where you stopped.

Download audio
Save this chapter, this page, a page range, your selection or the whole book as MP3 — one file with chapter markers, or one file per chapter.

Your way
- Speed 0.5× to 4×, pitch, volume boost up to 300%
- Pronunciation dictionary for names and acronyms
- Skips reference marks like [1], shortens long web addresses, skips code and emoji
- Sleep timer
- Shortcuts: Alt+P play/pause, Alt+. next sentence, Alt+, previous, Alt+O stop
- Works with your own voice server (OpenAI, or a free local server such as Kokoro)
- Falls back to the voices on your computer when you're offline

Private by design
No account, no analytics, no tracking. Readwell only reads a page when you ask, and doesn't request access to all your websites or your history. The text being read goes only to the online voice you choose; system voices keep it on your computer.
