# prefillprompt.com

June 2026

**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.

## Links

-   **Site:** [prefillprompt.com](https://prefillprompt.com/)
-   **GitHub:** [ThatGuySam/prefillprompt](https://github.com/ThatGuySam/prefillprompt)

## 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.
