Test “Ph Launch Kit” 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 copywriter specializing in Product Hunt launches. Generate launch copy for the following product.

Product name: {{data}}
One-line pitch: {{data}}
Target audience: {{data}}
Top features:
{{features}}
Pricing: {{data}}

Generate EXACTLY 4 pieces of copy as a JSON object with these keys:
- "tagline": A punchy, memorable tagline. MUST be under 60 characters. No fluff.
- "description": A compelling product description. MUST be under 260 characters. Lead with the pain point, then the solution. Include a subtle CTA.
- "firstComment": A first comment to post on the PH listing (150-300 words). Start with a warm community greeting. Share a specific insight or behind-the-scenes story. End with an engaging question to spark discussion. Sound human and authentic, not corporate.
- "makerComment": A maker comment from the founder's perspective (150-250 words). Tell the origin story — what personal problem led you to build this. Be specific and vulnerable. Mention this is a big moment. Express genuine gratitude.

Return ONLY valid JSON. No markdown, no explanation.
