How it works
Get a readiness score
Prototype Tester scores how complete your test protocol is against what makes usability sessions produce usable results.
Close the gaps and re-check
Define missing tasks, metrics, or screener criteria, then re-run the score before recruiting participants.

Frequently asked questions
Does this run live usability tests with real participants?
No — Prototype Tester plans and scores your test protocol on paper. It does not recruit, moderate, or execute sessions with real participants.
How many participants do I actually need?
Usability research broadly suggests around 5 participants catches most major issues in a single round — more helps but sees diminishing returns quickly.
Why does a think-aloud protocol matter?
Having participants narrate their thinking as they work surfaces why they struggle, not just where — this context is often more valuable than the completion rate alone.

Dedicated research platforms recruit and run live sessions, which this tool does not do. Prototype Tester scores and structures your test plan so those sessions, wherever they happen, are more likely to produce usable results.
