The Prompt Playground is a side-by-side workspace for writing and refining AI prompts before you send one to a model.
Open as many prompt panels as you need, load a ready-made template — summarize, extract, translate, rewrite, explain — and apply variants such as a chain-of-thought nudge, an expert persona, or a conciseness instruction. Each panel shows a live word count so you can see how a rewording changes length (and cost).
When a version looks right, copy it to your clipboard and paste it into ChatGPT, Claude, Gemini, or your own API call. Nothing you write here is transmitted — the playground is a private drafting surface.
Frequently Asked Questions
Does the playground call an AI model?
No. It is a drafting and comparison workspace: you write prompts here, then copy them into whichever AI tool you use. That also means no API key is required.
Can I compare more than two prompts?
Yes. Add or remove panels freely and compare as many prompt versions side by side as your experiment needs.
Are my prompts stored anywhere?
No. Prompts stay in your browser for the session and never leave your device.
