Prompt Playground

Build a better prompt, piece by piece

Use the six-part builder or write freely. The prompt checklist scores your prompt as you type, and you can compare two versions side by side.

Offline learning mode

Live AI isn't connected on this site right now, so prompts can't be run. Everything else works: the builder, templates, the prompt checklist and before/after comparisons. No responses are simulated.

Needs work

Role — Missing
No role found. Without one, the AI guesses what kind of expert to be.
Context — Missing
No background found — the AI doesn't know your situation, audience or goal.
Clear task — Pass
States the job with an action verb (“summarize”).
Constraints — Missing
No rules or limits found, so length, tone and scope are left to chance.
Output format — Missing
No output format found — you may get a wall of text when you wanted a list or table.
Examples — Missing
No examples found. Not always needed, but they're the fastest way to show style and format.
Specific wording — Pass
No vague filler words found.
Length — Partly
9 words — workable, but probably missing useful detail.
Delimiters — Not needed
No pasted material detected, so delimiters aren't needed.

Try next

Add 1–2 sentences of context: your situation, the audience, and what the result is for.
Say how to structure the reply, e.g. “Answer as 5 bullet points” or “Return JSON with keys …”.
Add 1–3 rules, e.g. “Keep it under 150 words”, “Use plain language”, “Don't invent facts.”
Open with a role, e.g. “You are an experienced teacher who explains things simply.”
