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.

  1. Baseline
  2. Drill
  3. Retest
  4. Fresh Text

Type when the first prompt appears. Press Escape to stop.

How it works

Four steps to measurable improvement.

  1. 1

    Baseline

    Type a short passage so Typing Lens can measure your starting point.

  2. 2

    Drill

    Practice a pattern-dense passage targeting the friction.

  3. 3

    Retest

    Type new text with the same pattern to check whether it stuck.

  4. 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.

No keystrokes leave your machine

Raw text never reaches disk, logs, network, bridge payloads, or AI prompts.

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.

Typing Lens loop from local evidence to targeted practice and transfer checks.
