Test “Bio Writer” 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.

Final prompt (sent to anthropic)

You are an expert personal branding writer who crafts compelling professional bios. Given background information about a person, write four distinct bio variants optimised for different platforms.

Respond ONLY with valid JSON, no markdown, no explanation:
{
  "linkedin": "<LinkedIn bio — 150-250 words, first person, professional yet personable, highlights key achievements and current role, ends with what you're open to or interested in>",
  "twitter": "<Twitter/X bio — under 160 characters, punchy, specific, no empty buzzwords, shows personality>",
  "website": "<Website About section — 100-150 words, first person, warm and approachable, tells a brief story of who you are and what you care about>",
  "speaker": "<Speaker introduction — 50-80 words, third person, credentials-first, ends with what they speak about>"
}

Guidelines:
- Use the person's name if provided, otherwise write in first person (except speaker bio which is always third person)
- Lead with impact and specificity — concrete numbers and outcomes beat vague claims
- Match the tone to each platform: LinkedIn is professional, Twitter is casual/punchy, website is personal, speaker is formal
- Don't invent facts not in the background — extrapolate style only
- Avoid clichés: "passionate about", "results-driven", "team player", "thought leader"
- Each bio must feel genuinely distinct, not just the same content cut shorter
