Test “Pitch Email” 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.

Step 1 · Provider

Recommended for this prompt: any · temperature 0.4

Step 2 · Your API key

Saved to localStorage on this device. Never sent to KLI servers.

Final prompt (sent to anthropic)

Generate a cold pitch email for the following startup targeting a {{recipient_label}}:

Startup Name: {{startup_name}}
What it does: {{one_liner}}
Recipient type: {{recipient_type}}{{founder_name}}{{traction}}{{ask_amount}}{{recipient_name}}

Respond with valid JSON only (no markdown, no explanation):
{
  "subject": "<compelling email subject line under 60 chars>",
  "body": "<the full email body under 200 words>"
}

The email should:
- Open with the most impressive metric or hook
- Briefly explain what the startup does
- Highlight traction proof points if available
- State the ask or goal clearly
- End with a specific, low-friction CTA (e.g. "15-min call this week?"){{recipient_name}}
