Everything it can do
Nine tools in three groups. Everything is off until you switch it on, and nothing is held back behind a payment.
📚 Reading — how the text itself looks
Readable
What it does. Rebuilds the text of the page: font, size, line spacing, letter spacing, word spacing, line width and background theme.
Who it helps. Almost everyone. It is the first thing to turn on and often the only thing you need.
Settings. Four fonts — Default, Simple, Classic and Dyslexia. Four themes — Off, Light, Dark and Sepia. Size, three separate spacings and line width are sliders you move until it feels right.
Bionic reading
What it does. Makes the first letters of every word bold, so the eye anchors on the beginning and completes the rest without stopping.
Who it helps. People who skim a lot, read in a second language, or find their attention sliding off long paragraphs.
Settings. Three strengths — Light, Medium, Strong. Start with Light; Strong is a lot on a long article.
Short phrase-lines
What it does. Breaks paragraphs into short lines, a few words each, instead of one full-width block.
Who it helps. Anyone who loses the line on the way back — a very common experience with dyslexia and with ADHD.
Settings. You choose how many words go on a line.
Reading time
What it does. Puts a small “≈ 9 min read” badge at the top of the article.
Who it helps. Anyone who needs to know what they are committing to before they start.
Settings. Pick your own pace — Slow (140 words per minute), Normal (200) or Fast (280) — and the estimate matches you rather than an average stranger.
🔢 How the number is worked out. It counts the words of the article itself, skipping menus, sidebars, footers, forms and code blocks, then divides by your pace. The badge appears only when a page has at least 200 words — roughly a minute of reading — so short pages stay clean.
🎯 Focus — where your eyes are
Reading ruler
What it does. A lit horizontal band follows your line, and the page around it dims.
Who it helps. The single most-loved tool for people who reread the same sentence without meaning to.
Settings. Band height and how strongly the rest of the page dims.
Guided reading
What it does. Shows the text one word — or a few words — at a time in the centre of the screen, so your eyes stop travelling altogether.
Who it helps. When focus is gone completely and even a clean page will not hold you.
Settings. Speed from 100 to 700 words per minute — 300 to begin with — and whether one, two or three words appear at a time. A small panel at the bottom has ▶ start, ⏸ pause and ⟲ restart.
💡 Worth knowing: select the passage you want first, then press ▶ — it will read exactly that. Without a selection it takes the main text of the page.
🌿 Calm & comfort — everything around the text
Calm
What it does. Stops animations, pauses autoplay video and freezes moving images.
Who it helps. Anyone distracted or made uncomfortable by movement at the edge of vision.
Honest limit. It does not catch everything — movement inside a video player or inside an advertising frame from another site stays. It makes the web calmer, and it is not a medical device.
Colour overlay
What it does. Lays a soft colour film over the whole page, in the spirit of the coloured sheets used on paper.
Who it helps. Some people find it reduces visual fatigue and the sense that letters are moving. Which colour works is personal — that is why there are six.
Settings. Yellow, peach, green, blue, rose or grey, and how strong the film is.
Declutter
What it does. Hides advertising blocks and cookie banners so the text has room.
Who it helps. Anyone reading on a page that is mostly not the article.
Honest limit. Sites are built differently, so occasionally it hides something you wanted. If that happens, switch it off — nothing breaks. A stronger mode also removes pop-ups and sign-up boxes.
