Clear answers about Dyslexly — reading tools, privacy, schools, and installation.
Dyslexly is a free Chrome dyslexia reading toolkit for most websites. It includes four font choices, 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.
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.
Yes. Core reading features — OpenDyslexic, Lexend and Atkinson fonts, 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 is optional: make selected text easier to read, plus writing tools, at £24.99 per year (about £2 a month).
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.
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.
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.
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.
Both are Chrome accessibility extensions. Dyslexly focuses specifically on dyslexia reading comfort — OpenDyslexic, overlays, line focus, and read-aloud are free without signup. HelperBird covers a broader accessibility feature set, often with subscription tiers for advanced tools. Choose based on which reading adjustments you use daily.
Yes. Schools and colleges can deploy Dyslexly via managed Chrome browsers or ask students to install it from the Chrome Web Store. Annual site licences cover unlimited students at one location — contact [email protected] for setup guidance, invoices, and licence keys.
Yes, with adult supervision for younger children. The reading tools are the same ones many students use for homework and research. Parents and teachers can enable only the features a child needs. Dyslexly does not require a child to create an account, and browsing activity is not sent to our servers.
Irlen Syndrome is one name used for a proposed explanation of visual discomfort while reading, but its definition and evidence remain debated. Some people prefer a coloured overlay, although results are inconsistent and it does not treat dyslexia. Dyslexly offers a free, reversible screen tint; persistent symptoms should be discussed with an eye-care professional.

Dyslexly keeps reading settings in Chrome storage and does not send page content to its servers. It records limited anonymous product events, and the optional uninstall survey can include the last active hostname, as explained at dyslexly.com/privacy. Email signup, checkout and support data are processed only when those services are used. Contact [email protected] for data requests.
