Dyslexia
Dyslexia is a learning disability that involves difficulty reading due to problems identifying speech sounds and learning how they relate to letters and words.
Every tool a dyslexic reader needs
Practical controls you can combine and test against your own reading preferences.
OpenDyslexic Font
Replace page fonts with OpenDyslexic, or compare Lexend, Atkinson Hyperlegible, Andika and the original system font.
Read the guide →Spacing Controls
Adjust letter spacing, word spacing, line height, and column width independently. Every dyslexic reader is different.
Colour Overlay
Test yellow, blue, green, pink or a custom page tint and keep it only when it feels more comfortable for you.
Read the guide →Line Focus
Dim the text outside a movable reading band to make it easier to follow one part of a page at a time.
Word-by-Word TTS
Highlight any text — Dyslexly reads it aloud and highlights each word as it speaks. Press Alt+Shift+R to start, Escape to stop.
Syllable Colours
Alternates two colours across detected syllables so longer words can be viewed in smaller chunks.

FAQ
What is Dyslexly?⌄
Dyslexly is a free Chrome dyslexia reading toolkit for most websites. It includes four specialist fonts plus the original system font, spacing, overlays, line focus, text-to-speech and PDF tools. Optional Pro is £24.99 per year (about £2 a month) or £4.99 per month.
How does Dyslexly help with dyslexia?⌄
Dyslexia primarily affects accurate and fluent word reading and spelling. Dyslexly provides adjustable fonts and spacing, line-tracking tools and text-to-speech so readers can choose a layout and reading method they prefer. It is assistive software, not a diagnosis or treatment.
Is Dyslexly free?⌄
Yes. Core reading features — OpenDyslexic, Lexend, Atkinson Hyperlegible and Andika fonts, the original system font, bionic reading, spacing, colour overlay, line focus, reading ruler, syllable highlighting, per-site settings and selection read-aloud — are free with no account required. Dyslexly Pro adds optional advanced reading and writing tools at £24.99 per year (about £2 a month) or £4.99 per month.
What is OpenDyslexic font and how does it help?⌄
OpenDyslexic is a free typeface with weighted bottoms and distinctive letter shapes. Research has not found a consistent or reliable improvement in reading speed or accuracy from dyslexia-specific fonts, but some readers prefer the design. Dyslexly lets you compare it with three other font choices on most compatible pages.
How do colour overlays help dyslexic readers?⌄
Some readers report visual discomfort on bright white backgrounds and prefer a tinted page. Evidence for coloured overlays is limited and inconsistent, and they do not treat dyslexia or help everyone. Dyslexly lets you compare a preset or custom tint with the original page and adjust its intensity.
What is line focus and how does it work?⌄
Line focus dims everything on the page except the line your cursor is on, so your eyes stay on one row of text at a time. Dyslexly also offers a reading ruler — a horizontal band that follows the mouse. Both tools reduce skipping lines or losing your place in long paragraphs.
Does Dyslexly work on all websites?⌄
Dyslexly works on most public web pages — news sites, email, Wikipedia, Google Docs, shopping sites, and school portals. Browser-internal pages (such as chrome:// settings), some heavily locked-down iframes, and PDFs opened outside Dyslexly’s PDF viewer may have limited support.
How is Dyslexly different from Helperbird?⌄
Both are accessibility extensions. Dyslexly focuses on a smaller dyslexia reading toolkit for Chromium browsers, with core reading controls free and no signup. Helperbird offers a broader free accessibility toolkit across more browsers and mobile platforms, with additional advanced tools in Pro. Choose based on the platforms and repeated tasks you actually use.
