ReadFocus — read faster, stay on the line.

A Chrome extension that makes long pages easier to get through: it bolds the start of each word so your eyes have somewhere to land, gives you a reading ruler that follows the mouse, dims everything but the paragraph you're on, and can switch the page to a dyslexia-friendly font. It runs entirely in your browser — no account, no server, no data collection.

Coming from Reader Mode, the official bolding extension or an ADHD reading extension that stopped working? See the side-by-side comparison: what each one does to the page, what it costs, and what their recent reviews report. Here for a reading ruler? That page compares the ruler extensions and shows the ruler on a PDF.

Free, forever

• Bold word starts — light, medium or heavy
• Wider spacing — the line, letter and word spacing dyslexia style guides recommend
• Reading ruler (Alt+Shift+R; colour, height, opacity, lock in place) and a per-site on/off switch (Alt+Shift+F)
• Works on articles, docs, forums and infinite-scroll feeds; never touches text you're editing
• PDFs on the web: "Read this PDF" opens the file in ReadFocus's own reader as real text, so every feature works on it (first page free; local files not yet)

Google Docs: ReadFocus cannot read the editor itself (Docs draws its text as graphics). For a document you only need to read, File → Share → Publish to web gives a normal page: switch ReadFocus on there.
