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.
Practising: Zero-shot prompting
Ask the AI to do a task directly, with clear instructions but no worked examples. The simplest technique and the right starting point.
A role sets expertise, vocabulary and perspective. Write it as “an experienced …”.
Who is this for, what's the situation, and what is the result used for?
Start with a clear action verb: write, explain, summarise, compare, list…
One rule per line: length, tone, what to avoid, what must be included.
Bullets, a table, JSON, headings, a specific number of items…
A short sample of the style or format you want. It's placed in a delimited block.
