Readit Fast streams articles one word at a time at up to 1,500 WPM — with AI comprehension quizzes that prove you retained it. No eye movement, no re-reading, no tab backlog.
Words stream through one fixed position on your screen. The Optimal Recognition Point (ORP) — the letter your eye naturally locks onto — is highlighted in focus orange. Your eyes never move, so they can never lose the line.
Pro tier groups related words into 2-4 word chunks based on syntax — "the quick brown fox" becomes one flash instead of four. Your brain processes phrases, not individual words, and chunking honors that.
Auto-generated quizzes prove you retained what you read. Because speed reading without comprehension is just scrolling fast. Pair with your own OpenAI, Anthropic, or OpenRouter API key.
The reader analyzes text difficulty (Flesch-Kincaid + semantic density) and slows down automatically for hard sentences. You set the target WPM; the reader handles the variance.
Extract any article body with one click. Strip the ads, headers, cookie banners, and nav. What remains is the actual content, ready to read at 500 WPM.
Nothing leaves your device except your own API calls. We never log URLs, store content, or track reading. Your reading history is yours.
Speed without comprehension is scrolling. We built Readit Fast around the idea that every article ends with a 3-question quiz — so you never have to guess whether you got it.
Whatever you pick, you're unlocking the full Pro toolkit: semantic chunking, AI comprehension quizzes, adaptive pacing, speed coaching, unlimited queue, and cross-device sync.

Rapid Serial Visual Presentation. Instead of reading a line of text with eye movements, a single word is flashed at a fixed position on the screen in rapid succession. Eliminates the time cost of saccades — your eyes stop, and comprehension speed becomes the bottleneck instead of eye-tracking speed.
Average reader: 200-250 WPM. Most Readit Fast users comfortably hit 400-500 after a week. Pro ceiling is 1,500 WPM. A 30-minute article becomes a 6-minute article at 1,500 WPM. Your mileage depends on content density and how hard you push.
Short answer: yes, up to a point, and the AI quizzes make it measurable. Most users maintain 85%+ comprehension up to 600-700 WPM, and some go higher. The quizzes exist so you don't have to guess.
