A Free, Open Alternative to Spritz
Spritz made one-word speed reading famous with its red-letter focus point. But Spritz is primarily a technology licensed to app developers — there is no simple website where you paste your own text. SpeedRead gives you that experience directly, free, for any text or document.
No signup. No install. Paste text and go.
About Spritz
Spritz Inc. developed the well-known "Spritzing" technique: words shown one at a time with the optimal recognition point (ORP) letter highlighted in red, keeping your eye anchored. The technology ships as an SDK inside partner apps rather than as a standalone consumer web tool.

Why readers switch to SpeedRead
- You want to spritz-read your own articles and documents right now, without hunting for an app.
- You want control over the focus point and highlight color instead of a fixed red letter.
- You want document upload with local, private parsing.
Where Spritz is a better fit
Spritz’s ORP alignment is genuinely good engineering, and apps built on it can be excellent. If an app you already use has Spritz built in, that integration may beat switching tools.
