The ClearFive method

Your launch, seen without context.

Familiarity hides friction. We give five people the same narrow mission and preserve what they actually did—not what they say they usually do.

See the complete evidence loop
01

First impression · five seconds

Can they explain what you made?

The first screen disappears before three memory-based questions. Your copy gets no second chance to explain itself.

02

One observable task

Can they complete the moment that matters?

A participant opens your live product and shares one browser window. You see hesitation, false starts, and the point of failure.

Critical taskCreate a workspace and invite one teammate.

Evidence → decision

What should change before launch?

Review recordings and answers, mark observations, then publish one verdict with three ranked fixes—each tied to evidence.

Feel the constraint

Five seconds removes the pitch.

Try the same memory test participants take. This is an interactive method demo, not a customer result.

Interactive method demo · 5 seconds

What does a stranger see before they scroll?

The screen disappears automatically. Answer only from memory.

The evidence workspace

A short path from “hmm” to “fix this.”

Every conclusion stays attached to a participant, response, or recording timestamp. ClearFive organizes judgment; it does not manufacture it.

“Start planning — choose a plan next” sets the correct expectation before the click.

  • Silent recording of the selected screen window
  • Founder evidence and observation workspace

A careful boundary

Observe the task.
Not private life.

Participants choose one browser window and approve silent screen recording explicitly. ClearFive never requests microphone or camera access.
