FocusFlow shows your reading one word at a time, at the pace you choose, with the focus letter highlighted. Your eyes don't move — your brain just reads.
Live demo. Try changing the speed.
Your brain processes language faster than your eyes can move. The eye movement is the bottleneck — and that bottleneck is exhausting. It's not a willpower problem. It's mechanical.
You read a paragraph and realize you absorbed nothing. So you read it again. And again.
The visual labor of tracking position drains attention before comprehension can happen.
"Read later" becomes "read never." Long-form content stops being something you finish.
Rapid Serial Visual Presentation (RSVP) is reading research that's been around for 50+ years. We just made it actually pleasant — with smart pacing, beautiful themes, and a focus letter that does the heavy lifting.
Your eyes stay still
No more saccades, no more line-finding.
The focus letter is highlighted
Your brain locks onto the word in milliseconds.
Smart pauses at sentences and headings
Comprehension stays high — this isn't 'speed reading bro' content.
Pick your pace
200 wpm or 500 wpm. You're in control.
Try a paragraph from an article you've been putting off. Pick a theme. Hit play.
Theme
Natural pauses at sentence ends, paragraph breaks, headings, and long words. Comprehension stays high.
Each word's optimal recognition point is highlighted in your theme color. Word recognition becomes instant.
Warm, Sepia, Dark, and Midnight. For mornings, evenings, and whatever your eyes need.
Paste text, upload PDF / EPUB / DOCX, fetch any URL, or read the page you're on with the Chrome extension.
See the whole document at once. Click any sentence to jump there. Never lose your place.
Titles and headings are visually emphasized as you pass through them — structure stays intact.
Close the tab mid-read. FocusFlow remembers exactly where you stopped.
Space to play/pause, ←/→ to skip, Esc to close. Built for flow, not menu-hunting.
Reading happens in your browser. No analytics, no tracking, no selling your data. Ever.
ADHD brains
Built around how your brain actually works. External pacing, no self-regulation tax, and articles you'll actually finish. Not a productivity hack — a different way to read.
Dyslexic & visually-sensitive readers
Reduced visual crowding, no lateral eye movement, and a clean focal point. Not a cure — a different way to read that strips out visual load.
Students & avid readers
Read at 250–500 wpm with comprehension preserved. We cite Rayner (2016). We don't promise magic. We just remove the bottleneck.
Every other reading tool overpromises. We won't. Here's the honest version.
✓ Genuinely better for
✗ Not the right tool for
For those, traditional reading is still better. Use FocusFlow for the rest — which is most of it.
FocusFlow isn't built on hype. RSVP is real psycholinguistic research and we cite the studies. We're also careful not to overclaim — that's the difference.
Rayner, K. et al. (2016) — "So Much to Read, So Little Time"
The gold-standard meta-analysis. RSVP preserves comprehension up to ~500–600 WPM for most readers.
Optimal Recognition Point
A real psycholinguistic concept. Word recognition is fastest when fixation lands slightly left of the word's midpoint — exactly where we highlight it.
What we don't claim
No clinical claims for ADHD or dyslexia. No 1000+ WPM promises (comprehension drops above ~600 WPM for almost everyone). Honest tools beat magical ones.
