Spectraless vs SpeedReader

Spectraless is a Safari extension for removing the Spectral font from Substack newsletters in order to improve their readability. It works on newsletters that use the substack.com domain as well as those using custom domains.

## App Description Reading shouldn't be this hard. SpeedReader is a free Safari extension that lets you speed read any web page using RSVP (Rapid Serial Visual Presentation) — showing one word at a time at a controlled pace. For neurodivergent readers — people with ADHD, dyslexia, or other processing differences — traditional reading is exhausting. Eyes jump between lines, focus drifts mid-paragraph, and articles get abandoned halfway through. RSVP removes the cognitive overhead of eye tracking and line scanning, so your brain just processes. **How it works** Tap the SpeedReader icon in Safari's toolbar. The article text is extracted automatically and words appear one at a time with a highlighted focus point. Tap anywhere to pause, tap again to resume. That's it. **Features** • Focus-point highlighting — each word highlights its optimal recognition point, the letter your eye naturally anchors to • Context preview — pause and see the surrounding sentence to re-orient quickly • Punctuation pacing — periods and commas add natural micro-pauses so content flows like speech • Speed control — 100 to 600 words per minute • OpenDyslexic font — toggle the dyslexia-friendly font with one tap • Light and dark mode — follows your system theme or override manually • Keyboard shortcuts — on Mac and iPad: Space to play/pause, arrows to navigate • Text selection fallback — select any text on a page and speed read just that • Works entirely offline — no data leaves your device No accounts. No subscriptions. No tracking. Free and open source.
