How do I use Prompt Lab?

Write a prompt, run it, change one thing, and compare versions. The lab scores whether you included context, constraints, and an example.

Updated 8/23/2026

Pick a challenge
Prompt Lab ships with guided challenges such as explaining a limit of AI or writing a safer research prompt. Stay inside one challenge so the versions are comparable.
Change one variable
A useful second version changes audience, format, or a constraint — not everything at once. Run both and read the side-by-side output plus the analysis chips.
Without a live model
If AI Gateway is not configured, Prompt Lab still runs against the offline Guide. The analysis of context, constraints, and examples is the lesson even when the model is a mock.
