The fun way to write — and think — clearly.

Bite-size games that turn fuzzy sentences into ones that can only mean one thing. Lumi, our lighthouse, shows you exactly how a reader could get you wrong.

What is ClarifyMe?

If a sentence can mean two things, someone will read the other one. ClarifyMe is a daily workout for saying exactly what you mean — in emails, requirements, specs and arguments.

Users should get a reply soon.

Soon = 5 minutes or 5 days?

Step 1

Write it

Write a line or two for a small task. Lumi reads it the way a lawyer, a compiler or a tired engineer would.

“The reset link expires after a while.”

  • How long is “a while”?
  • What if it's used twice?
  • 6 more hiding…

Step 2

Break it

Read a loose spec and hunt the corner cases it forgot — the way TLA+ hunts for a bad trace.

Counterexample

“it” could mean the server, not the file — and the server gets deleted.

Step 3

See the counterexample

Instant feedback from clear rules plus an AI reader — not just a score, but the exact way you could be misread.
