Re prompt by Halim

Re prompt adds a single ✨ button next to the send box on ChatGPT, Claude, and Gemini. Type a rough draft, click the button, and it instantly rewrites your prompt into a clear, structured, expert-quality
version — then places the result back in the input box, ready to send.

How it works
The extension sends your draft to the AI provider of your choice (OpenAI, Anthropic, Groq, or Gemini) using your own API key. The rewritten prompt is streamed back and injected directly into the page — no
copy-pasting, no switching tabs.

Built-in rewrite presets
- Expert prompt — adds role, context, constraints, and output format
- Make it shorter
- Expand with detail
- More formal / More casual
- Translate to English
- Fix grammar

You can also add your own custom presets with any system prompt you like.

Privacy first
Your API keys are stored locally in your browser using storage.local. They are sent only to the provider you choose (OpenAI, Anthropic, Groq, or Gemini) and nowhere else. No data is collected, no account
required.
