Test “Letter Of Recommendation” 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)

Write a professional letter of recommendation with the following details:

Candidate name: {{candidate_name}}
Recommender name: {{recommender_name}}
Relationship between recommender and candidate: {{relationship}}
{{purpose_line}}
{{strengths_line}}
{{achievements_line}}

Write a compelling, professional letter of recommendation that:
1. Opens with how the recommender knows the candidate and for how long
2. Highlights the candidate's key strengths with specific examples
3. Mentions any notable achievements or contributions
4. Makes a strong case for why the candidate is recommended
5. Closes with an enthusiastic endorsement and offer to provide further information
6. Is appropriately formal and 3-4 paragraphs long

Return only the letter text, nothing else.
