35+ Reading Accessibility Tools
Every feature is free, private, and works instantly. Organized across 5 categories to help readers of all abilities.
Every feature below is grounded in peer-reviewed neuroscience research on dyslexia, ADHD, and cognitive accessibility.
Reading
10 toolsReader Mode
Strip ads, sidebars, and clutter for a clean reading view. Removes extraneous cognitive load that increases distractibility in ADHD readers.
Typography
Font, size, spacing, line height, and alignment controls. Extra-large letter spacing can double reading accuracy in dyslexic readers.
Overlay
Color tints to reduce visual stress. Addresses cortical hyperexcitability in Meares-Irlen Syndrome, affecting up to 46% of dyslexic readers.
Reading Ruler
Focus ruler, screen mask, and reading guide. Digital rulers improve reading speed by an average of 86 words per minute.
Line Tracking
Alternating line colors, borders, or active line highlight. Prevents line-skipping caused by binocular vision difficulties.
Text Size
Quick access to text size adjustment. Research recommends 18pt to 26pt for maximum digital readability.
Bionic Reading
Bold the first part of each word to guide fixation. Creates artificial anchoring points that scaffold focus for ADHD readers.
Line Focus
Highlight 1, 3, or 5 lines at a time. Narrows the visual attention span to reduce interference from surrounding text.
Progress Bar
Show reading progress at the bottom of the page. Combats ADHD time blindness by making remaining effort spatially visible.
Auto Scroll
Automatically scroll the page at a set speed. Leverages the brain's hardwired tracking reflex to maintain forward reading momentum.
Audio
5 toolsText to Speech
Read page aloud with word-by-word highlighting. Meta-analyses show TTS produces significant comprehension gains by offloading the decoding bottleneck.
Voice Typing
Speech-to-text dictation. Bypasses the transcription bottleneck that consumes working memory in dyslexia and dysgraphia.
Speed Read
RSVP speed reading mode. Eliminates saccadic eye movement planning, boosting ADHD comprehension by nearly 13%.
Volume Boost
Boost page audio volume up to 200%. Increases the signal-to-noise ratio for multi-channel learning environments.
Hover to Listen
Hear text aloud by hovering over it. Provides on-demand auditory reinforcement without disrupting visual reading flow.
Annotation
4 toolsHighlight
Multi-color highlighting with export. Warm colors like red and yellow heighten arousal and create dual memory pathways for higher retention.
Sticky Notes
Draggable notes that persist on any page. Functions as cognitive load displacement — an external memory aid for ADHD working memory limits.
Notes
Quick notepad for jotting thoughts. Active notetaking during reading facilitates encoding gains independent of later review.
Reading List
Save articles for later reading. Reduces task-switching drain and supports deep engagement by batching reading tasks.
Language
7 toolsDictionary
Click any word for definition and pronunciation. Reduces intrinsic load from unfamiliar vocabulary that causes decoding failure.
Translate
Hover any word for instant translation. 100+ languages. Lowers the cognitive cost of processing unfamiliar words in a second language.
Text Stats
Word count, reading level, estimated read time. Anticipating effort helps ADHD readers approach dense texts with realistic expectations.
Word Prediction
Predictive text suggestions while typing. Context-aware completions reduce working memory load and help unstick ideas.
Morphemes
Highlight prefixes, roots, and suffixes. By age 10, morphological awareness becomes a stronger predictor of decoding ability than phonology.
Picture Dict
Visual dictionary with images for words. Leverages the picture superiority effect — the brain remembers visuals more efficiently than text alone.
Simplify
AI-powered text simplification. Prototype testing showed reading time reduction of over 82% for complex technical content.
Accessibility
9 toolsFocus Timer
Pomodoro timer for reading sessions. Addresses ADHD time blindness by turning abstract time into visible, manageable intervals.
Parts of Speech
Color-coded nouns, verbs, adjectives, adverbs. Implements Colorful Semantics, a clinical method shown to improve sentence comprehension.
Syllables
Visually split words into syllables. Syllable-based training shows strong effect sizes in word recognition fluency and pronunciation.
Save EPUB
Download current page as EPUB for offline reading.
Dark Mode
Apply dark theme to pages. Reduces luminance and screen glare for readers with photophobia or sensory sensitivity.
High Contrast
High contrast color modes for readability. Filters wavelengths to prevent cortical over-excitation from high-energy striped patterns.
Visual Aids
Grayscale, hide images, link colors, cursor, zoom, and more. Reduces visual clutter and sensory overload in digital environments.
Classroom
Cloze exercises, analytics, vocabulary, paragraph numbers. Cloze exercises build the ability to use semantic and syntactic cues for comprehension.
