How it works

Three steps to clearer reading

Install once, then ReadEase works invisibly on every webpage you visit.

01
Add ReadEase to Chrome
One click install from the Chrome Web Store. No sign-up, no account, no setup. Completely free.
02
Visit any webpage
ReadEase works automatically on educational content — articles, revision sites, online textbooks, any webpage with text.
03
Important words stand out
AI scores every word for importance and subtly emphasises the key terms across five tiers — so your brain processes them faster.
Who it helps

Built for every kind of reader

Reading difficulties affect one in five students. ReadEase levels the playing field without singling anyone out.

🧠
Students with dyslexia
Visual emphasis reduces cognitive effort, helping dyslexic readers process content more efficiently.
⚡
Students with ADHD
Important words act as visual anchors, making it easier to follow dense paragraphs to the end.
📚
Struggling readers
Clear visual hierarchy helps extract meaning even when reading fluency is limited.
🌍
EAL learners
Students in a second language can identify which unfamiliar words are worth looking up.
The five tiers

Not all words are created equal

Every word lands in one of five importance tiers. Subtle enough to read naturally — clear enough for the brain to notice.

Research-backed

Built on proven science

ReadEase is grounded in peer-reviewed research on visual attention and reading. Our formatting is calibrated to established findings about how the eye processes emphasised text.

👁️
Eye Movement Research
Eye movement research shows that typographic emphasis creates visual anchors that guide where readers fixate. Emphasised words receive longer fixation duration, which can improve information retention during reading.
Rayner, K. (1998). Eye movements in reading and information processing. Psychological Bulletin, 124(3), 372–422.
🔤
Font Type for Dyslexic Readers
Sans serif, monospaced and roman font styles significantly improve reading performance for dyslexic readers compared to serif, proportional and italic fonts. This finding comes from eye-tracking studies with 48 participants with dyslexia.
Rello, L. & Baeza-Yates, R. (2013). Good fonts for dyslexia. Proceedings of ASSETS 2013, ACM.
⚖️
Preattentive Processing
Subtle typographic differences can be processed preattentively — meaning the brain registers visual differences before conscious awareness. ReadEase uses minimal weight and size changes designed to operate below the threshold of conscious detection.
Laarni, J. (2002). Effects of font format and text complexity on reading efficiency. Proceedings of NordiCHI.
🧠
Cognitive Load Theory
Visual cues in text can reduce working memory demands during reading by making semantic structure more apparent. This allows readers to allocate cognitive resources to comprehension rather than scanning for meaning.
Pammer, K. (2014). Visual factors in reading. Current Directions in Psychological Science, 23(1), 42–48.
Why AI emphasis matters
ReadEase uses Claude AI to score words for semantic importance rather than applying emphasis arbitrarily. Research shows that visual emphasis only helps comprehension when it aligns with genuine meaning — random emphasis can actually impair understanding. Our AI ensures that emphasised words genuinely matter to the text.
