FLOW runs entirely client-side — no server, no account, no uploads. It parses 13 file formats natively in the browser, including MOBI/AZW via a hand-rolled PalmDOC decompressor, EPUB, PDF, DOCX, and Markdown. No competitor does that without a backend. The speed ramp engine uses a cubic ease-in curve (120→650 WPM) that mirrors how reading cognition actually works, paired with optical pivot highlighting on each word's focal letter. Zero config, drag-and-drop, light/dark themes, fully private.

Hey PH! I built FLOW because every speed reader I tried either wanted me to paste plain text or sign up for an account just to read my own files. FLOW runs 100% in your browser. Drop an EPUB, PDF, MOBI, Markdown, DOCX (13 formats total) and it starts flashing words using RSVP. No server ever sees your books. The part I'm proudest of: the speed ramp. Instead of a fixed WPM, it eases you from 120 to 650 using a cubic curve so your brain locks in before it speeds up. Tiny detail, huge difference. Would love to hear what formats or features you'd want next 👇

Great experience overall!

It would be great if you could add speed settings and support for additional languages and scripts—for example, Cyrillic for Russian.
