Test “Cold Outreach” 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.

Step 3 · Fill the variables

Final prompt (sent to anthropic)

You are an expert at writing personalized cold outreach messages that get responses.

Write a compelling cold outreach message with the following details:
- Sender name: {{sender_name}}
- Recipient role: {{recipient_role}}
- Value proposition: {{value_proposition}}

Write a professional, concise cold outreach message (3-4 short paragraphs). Make it feel personal and genuine, not salesy. End with a clear but low-pressure call to action for a brief conversation.

Return ONLY the message text, no subject line, no extra commentary.
