Train your reading speed in the browser. Two modes, zero runtime dependencies, all data stays on your machine.
Most adults read at 200-300 wpm. Reading faster is mostly a pacing problem: the eyes wander, re-read out of habit, and linger longer than recognition requires. This trainer gives your eyes a metronome (a moving highlight or a flashing word) so you read at a deliberate, gradually increasing pace instead of an accidental one.
It is grounded in reading research rather than speed-reading hype: the speed slider stops at 600 wpm, because beyond that comprehension measurably drops (see The science below).
A warm paper page. A moving highlight over a chunk of 1-5 words paces your eyes down the text; the page autoscrolls to keep the chunk in view. Click any word to rewind to it: re-reading is part of comprehension, not a failure. A progress bar shows position and estimated time remaining.
A dark stage showing one word at a time, centered, with the optimal recognition point (ORP) letter accented so your eyes never have to move. Pauses automatically: ×2 at sentence-ending punctuation, ×1.3 at commas, ×1.5 at long words.
- Open the live demo. A demo text ("How fast can you read?") is preloaded when the library is empty.
- Load your own text: the Paste button or
Ctrl+V, the file picker (Ctrl+O), or drag & drop a file onto the page. Shortcuts show as⌘V/⌘Oon macOS. - Pick a mode, press
Space, read. - Adjust speed with the slider or
←/→(±25 wpm). Optional auto-progression adds +10 wpm every 2 minutes. - Come back anytime. Per-text progress, the text library, and session stats (with a wpm chart) live in localStorage.

Built on reading research (Rayner et al., 2016, So Much to Read, So Little Time):
- Chunk highlighting works as a pacer, not as "reading word groups". The benefit is rhythm, not magic.
- Regressions (re-reading) matter for comprehension, hence click-to-rewind instead of forced forward-only flow.
- Speeds above ~600 wpm trade away comprehension, so the slider deliberately stops there.
