No keystrokes leave your machine
Raw text never reaches disk, logs, network, bridge payloads, or AI prompts.
A typing coach for developers and writers
Type better by fixing what actually slows you down.
Try a short browser practice session. The Mac app uses local pattern data to find the patterns that cost you accuracy, rhythm, or corrections.
No account needed. Three minutes to try.
Measured practice is for desktop physical keyboards. Phones are best for reading the product story.
Preparing browser demo
Ready
This browser demo starts with a session-local calibration baseline.
- Baseline
- Drill
- Retest
- Fresh Text
Type when the first prompt appears. Press Escape to stop.
How it works
Four steps to measurable improvement.
-
1
Baseline
Type a short passage so Typing Lens can measure your starting point.
-
2
Drill
Practice a pattern-dense passage targeting the friction.
-
3
Retest
Type new text with the same pattern to check whether it stuck.
-
4
Fresh text
Try different text before the session calls it progress.
The Mac app
The demo shows the loop. The Mac app makes it yours.
Install the app and Typing Lens watches everyday typing friction locally. It stores only saved pattern stats, never raw text, and recommends practice from your local profile.
Your profile learns with you
Saved pattern data builds over time. Practice adapts as your typing changes.
One download, no account
No sign-up, no login, no cloud sync, no cookies, and no analytics.
The approach
Built around how learning actually works.
Speed without accuracy isn't progress. Every session starts with getting it right.
Corrections count
Backspaces and error bursts are not hidden. They are measured and trained.
Honest measurement
Small sessions give useful data without pretending to know your whole profile.
