Test “Rebrand Announcement” 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 a professional communications writer. Generate a rebrand announcement for the following scenario:

- Old company/product name: {{old_name}}
- New company/product name: {{new_name}}
{{launch_date}}
- Reason for rebrand: {{reason_for_rebrand}}
{{what_changes}}
{{what_stays_the_same}}
- Target audience: {{resolved_audience}}
- Tone: {{resolved_tone}}

Write a professional rebrand announcement. Return ONLY a JSON object with two fields:
1. "subject" - an email subject line for the announcement (concise, compelling)
2. "announcement" - the full announcement body text (use \\n for line breaks, no markdown formatting)

Return only the raw JSON object, no code fences.
