Most people who read fluently never stop to think about what the page actually looks like to someone with dyslexia. Letters hold still, words stay in order, and sentences arrive in a straight line. For roughly 1 in 10 people, that experience is different — letters may appear to swap, blur, jump, or crowd together, and the effort of decoding turns reading into a workout instead of a reflex. The websites and tools below exist to close that empathy gap. Some simulate the visual distortions, some let you feel the decoding fatigue, and some are simply built by dyslexic designers so the reading experience is easier from the start. Start with the one that sparked this list, then explore the rest.

Why Reading Simulations Change How You See Dyslexia
Dyslexia is invisible. A child who reads slowly can look unmotivated; an adult who avoids long emails can seem disorganized. But when a fluent reader spends sixty seconds inside a simulation — watching letters jitter, words reverse, or a paragraph dissolve into a blur — the misunderstanding evaporates. Teachers start designing worksheets differently. Parents stop saying “just try harder.” Managers rethink that wall of text in the team update. The tools below fall into three rough families: visual simulators that distort text on purpose, accessibility tools that remove the distortion in real life, and typefaces designed to reduce it. Together they form a kind of empathy toolkit — one that lets you feel the problem and then see the fix.
15 Websites That Show What Reading Feels Like as a Dyslexic
1. Dyslexia Simulation (Nessy) : The original “feel it yourself” text distortion
What it is: A free browser-based simulation from Nessy, the literacy company, that scrambles and distorts a short passage so you can attempt to read it the way a dyslexic reader might experience it.
Category: Visual simulation
Why it stands out: It is the tool that started this whole list. The passage is deliberately short — about a paragraph — but most fluent readers need far longer than expected and still miss words. Letters wobble, spacing shifts, and the effort is immediate.
Best for: Teachers, parents, and anyone who has ever thought a struggling reader just needed to focus harder.
2. OpenDyslexic : A free typeface that anchors letters in place
What it is: An open-source font designed so each letter has a heavier bottom, giving the eye a visual anchor and reducing the flipping effect some readers describe.
Category: Accessible typeface
Why it stands out: It is completely free and installs in seconds on Mac, Windows, and in most browsers. Because it is open source, it also powers a huge number of reading apps and browser extensions behind the scenes.
Best for: Dyslexic readers who want a simple, no-cost font swap on their own devices.
3. Dyslexia Fonts by Daniel Britton : Type that removes letters to show the struggle
What it is: A designer’s project that strips away parts of each letter so words become nearly unreadable — a deliberately extreme demonstration of decoding difficulty.
Category: Empathy design project
Why it stands out: Rather than wobbling letters, it removes information. The result is a visceral “I can’t do this” moment that visual simulations sometimes miss, because it mimics the exhaustion of guessing at words.
Best for: Workshop facilitators and anyone presenting dyslexia awareness training.
4. WebAIM Dyslexia Simulation : A research-backed look at reading barriers
What it is: WebAIM’s cognitive accessibility resources include simulations and explanations of how text layout, contrast, and spacing affect dyslexic readers.
Category: Accessibility education
Why it stands out: It pairs the simulation with concrete design fixes — line spacing, shorter lines, left-aligned text — so you leave with solutions, not just discomfort.
Best for: Web designers and content creators who want practical, citable guidance.
5. Understood.org Simulations : Interactive experiences for parents and classrooms
What it is: A nonprofit resource hub with interactive simulations and explainers that walk you through what reading, writing, and focus challenges can feel like.
Category: Family and classroom resource
Why it stands out: The language is written for non-specialists, and each simulation is paired with a plain-English explanation of what is happening and what helps.
Best for: Parents who are newly navigating a diagnosis and want to understand their child’s day.
6. Microsoft Immersive Reader : The fix, built into everyday software
What it is: A free reading tool built into Microsoft Edge, Word, and Teams that can change spacing, split words into syllables, read text aloud, and highlight lines.
Category: Accessibility tool
Why it stands out: After you have felt the simulation, this is the antidote. Line focus and syllable splitting are genuinely transformative for many readers, and it works on real web pages in Edge.
Best for: Students and office workers who read long documents daily.
7. Helperbird : A browser toolkit for customizing any page
What it is: A browser extension that adds dyslexia-friendly fonts, text-to-speech, reading rulers, color overlays, and spacing controls to almost any website.
Category: Browser extension
Why it stands out: The reading ruler — a colored bar that follows your cursor — is a small feature that makes a big difference for line-tracking. A free tier covers the basics.
Best for: Adults who read a lot online and want one extension to fix every site.
8. BeeLine Reader : Color gradients that guide the eye
What it is: A tool that applies a subtle color gradient across lines of text so the eye is pulled from the end of one line to the start of the next.
Category: Reading aid
Why it stands out: It targets a specific, common struggle — losing your place between lines — with a visual trick rather than a font change. The effect is surprisingly easy to get used to.
Best for: Readers who constantly re-read the same line.
9. Dyslexia the Gift (Davis) : First-person accounts of what it feels like
What it is: The Davis method’s long-running site collects descriptions and exercises that explain how dyslexic perception differs, including orientation and picture-thinking.
Category: Perspective and method
Why it stands out: Simulations show the visual side; this site explains the cognitive side — why some readers think in pictures and how that affects reading. It is a useful companion to any simulator.
Best for: Anyone who wants the “why” behind the distortion.
10. Lexend Font : A typeface tuned for reading fluency
What it is: A free font family designed with reading-proficiency research in mind, with generous spacing and simplified letterforms.
Category: Accessible typeface
Why it stands out: It is available free through Google Fonts, so you can test it on a real document in minutes. Many readers report it feels calmer than standard fonts without looking unusual.
Best for: Designers and teachers choosing a default font for handouts.
11. Read&Write by Texthelp : A full reading and writing companion
What it is: A toolbar that adds text-to-speech, word prediction, dictionary lookup, and screen masking to documents and web pages.
Category: Assistive software
Why it stands out: The screen mask dims everything except the line you are on, which is a direct answer to the “letters swimming on the page” feeling. A free 30-day trial lets you test it properly.
Best for: Students with formal accommodations and their teachers.
12. Voice Dream Reader : Listening instead of decoding
What it is: A text-to-speech app for iOS and Android that reads documents, ebooks, and web articles aloud with synchronized highlighting.
Category: Text-to-speech app
Why it stands out: Hearing a word while seeing it highlighted builds the sound-symbol link that struggling readers often miss. The voice quality is among the best in its class.
Best for: Readers who absorb content far better by ear.
13. Dyslexia Advantage Simulation : A quick distortion demo with context
What it is: A short interactive demo that shows how text can appear to shift and blur, framed with explanations of common classroom signs.
Category: Visual simulation
Why it stands out: It is short enough to run in a staff meeting and specific enough to spark real conversation about accommodations like extra time and oral instructions.
Best for: Quick awareness sessions and team training.
14. Atbar Accessibility Toolbar : A free, no-install page fixer
What it is: A bookmarklet-style toolbar from the University of Southampton that changes font size, spacing, contrast, and reads text aloud on any page.
Category: Accessibility toolbar
Why it stands out: It runs without installing an extension, which makes it handy on shared or school computers where you cannot add software.
Best for: Library and lab computers where installs are locked down.
15. Dyslexie Font : A commercial typeface with a clear purpose
What it is: A paid font family designed to make letters more distinguishable by varying shapes and adding subtle weight differences.
Category: Accessible typeface
Why it stands out: It is one of the most widely adopted dyslexia-focused fonts in publishing and education, and the site explains the design rationale letter by letter. It is a paid product, so test the free samples first.
Best for: Schools and publishers standardizing on an accessible font.

The Empathy Shortcut Worth Sharing
None of these tools can fully reproduce another person’s experience — dyslexia varies enormously from reader to reader, and a sixty-second simulation is only a glimpse. But a glimpse is often enough to change a habit: to shorten a paragraph, add extra time, or stop assuming that slow reading means low effort. Start with the Nessy simulation if you want the feeling, then try Immersive Reader or Lexend if you want the fix. Share one of them with a teacher, a manager, or a friend who has never quite understood the struggle. Which one surprised you most — and do you have a favorite accessibility tool that did not make this list?
