ADHD Bionic Reader

ADHD Bionic Reader applies the Bionic Reading technique to every webpage you visit - automatically bolding the first letters of each word so your eyes have natural anchor points to follow. This reduces cognitive load and helps you stay focused while reading articles, documentation, social media, or any other text-heavy content. --- HOW IT WORKS Bionic Reading is a scientifically-inspired method that guides the eye by emphasising the most recognisable part of each word. Your brain completes the rest, allowing you to read faster and with less mental effort - particularly helpful for people with ADHD, dyslexia, or anyone who struggles with long-form reading. --- KEY FEATURES • Global one-click toggle - enable once, works on every tab automatically from that moment forward. Persists across browser restarts. • 5 intensity levels - from subtle (level 1) to maximum (level 5). Adjust how many letters are bolded per word to match your reading style. • Live preview - see the effect on sample text before applying it to any page. • Smart word detection - correctly handles punctuation, numbers, and mixed content. Supports Latin and Polish characters (ą, ć, ę, ł, ń, ó, ś, ź, ż). • Fully non-destructive - disable the extension and every page instantly reverts to its original text, no reload needed. • Works on dynamic pages - infinite scroll, single-page apps (Twitter/X, Reddit, Medium, Wikipedia) are handled via MutationObserver. • Respects sensitive areas - code blocks, input fields, editable regions, buttons, and iframes are never modified. • Performance-friendly - processing is batched in the background using requestIdleCallback so page responsiveness is never affected. • Advanced settings page - customise the bolding algorithm per word-length range, change font weight (700/800/900), enable color-highlight mode, manage per-domain exceptions, view total word stats, and import/export your configuration as JSON. --- PRIVACY This extension does not collect, transmit, or store any personal data. All settings are saved locally in your browser via chrome.storage.sync. No analytics, no tracking, no external servers. --- PERMISSIONS EXPLAINED • storage - saves your settings and intensity preferences • activeTab - reads the current tab URL to check for excluded domains • scripting - injects the reading script into pages when enabled • host_permissions: all_urls - required to work on any website you visit --- OPEN SOURCE The full source code is available on GitHub. Contributions and feedback are welcome. --- Works on Chrome 88+ (Manifest V3). Does not work on chrome://, edge://, or browser-internal pages.
