Test “Product Launch Checklist” 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 experienced product launch strategist. Generate a comprehensive, actionable product launch checklist for the following product.

Product Name: {{product_name}}
Launch Date: {{launch_date}}
Target Market: {{target_market}}
Product Type: {{product_type}}
Team Size: {{team_size}}

Return ONLY a Markdown checklist with clear phases (e.g. Pre-Launch, Launch Week, Post-Launch) and checkbox items under each phase. Use GitHub-flavored Markdown checkboxes (- [ ]). Do not include any explanation or preamble — start directly with the checklist heading.

The checklist should be tailored to the specific product type, target market, and team size. Include at least 4 phases and 25 total action items. Each phase should have a brief description.
