Test “Contract Termination Letter” with your own key

Paste an Anthropic, OpenAI, or OpenRouter key. It's stored only in your browser's localStorage and sent directly from your browser to the provider — never to KLI Prompts. We have no backend that can see it.

How this works (honestly)

Your key lives in localStorage on this device only.
The HTTP request to the LLM goes from your browser straight to api.anthropic.com / api.openai.com / openrouter.ai.
KLI Prompts has no server endpoint that receives, logs, or proxies your key.
Clear it any time — there's a button below.
