SpeedReader: Juice turns long text into focused one-word reading sessions. Paste text, import a public URL, open an article in the built-in browser, scan a screenshot with on-device OCR, or bring in a PDF, then read at your chosen pace with a fixed visual anchor. The reader is built for quick, repeatable reading sprints: - One-word-at-a-time display with adjustable words per minute - Fixed eye anchor and optional bold/color focus - Adaptive pauses for punctuation and longer words - Built-in browser and favorite sources - Local library, reading stats, and saved profiles - Image OCR and PDF text import Daily reading allowances are clear and visible in Settings. Everyone gets 1,000 words per day free, with optional paid tiers for higher daily limits. SpeedReader processes imported text locally where possible. URL import fetches the public page you choose; the app does not bypass paywalls or send article text to a SpeedReader backend.
