prefillprompt.com

Type in a prompt and get a link that auto-starts the conversation.

prefillprompt.com lets you save and share prompts across ChatGPT, Claude, and Perplexity. Generate a link, share it, and the chat opens with the first message already typed — no copy-paste, no retyping instructions.

Highlights

  • One link, prefilled — whoever opens it lands in a chat with your prompt already entered.
  • Works across providers — ChatGPT, Claude, and Perplexity URL formats.
  • Tiny surface area — no accounts, no storage, just link generation.
  • Open source — examples and a contribution flow in the README.

How It’s Built

  • Frontend — Nuxt, Vue, Vue Router, and TypeScript, with server routes that build and redirect the prefilled prompt URLs.
  • UI — Nuxt UI and VueUse over a simple responsive generator.
  • Link generation — query-string construction with qs, provider-specific URL formats, and an /api/prompt route for shareable links.
  • Runtime & tooling — a Node engine, Nuxt build/generate scripts, pnpm, ESLint, and vue-tsc type checking.
