Test “Reference Letter” 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.

Final prompt (sent to anthropic)

Write a professional reference letter for the following context:

Writer: {{writer_name}}{{writer_title}}
Candidate: {{candidate_name}}
Relationship: {{relationship}}{{duration}}{{strengths}}{{specific_examples}}
Purpose: {{resolved_purpose}}

Write a complete, professional reference letter with:
1. A proper salutation (use "Dear [Appropriate Recipient]," if no specific recipient is known)
2. An opening paragraph establishing who the writer is and the nature of the relationship
3. Two or three body paragraphs highlighting the candidate's strengths, skills, and specific accomplishments
4. A closing paragraph with a strong endorsement and offer to provide further information
5. A professional sign-off with the writer's name and title

Make the letter warm, specific, and compelling. Tailor the tone and content for the stated purpose ({{resolved_purpose}}).
