PromptEnhance

Select text in any editable field on any web page — a chat box, a form, anything — > click the ✨ Enhance button that appears, and the selection is rewritten in place > into a sharper prompt. > > Runs entirely as a browser extension with no external server of ours involved. You > bring your own API key for whichever provider you want: Anthropic (Claude), OpenAI, > Google (Gemini), OpenRouter, or a fully local, offline setup via Ollama or LM > Studio. Your key and settings are stored only in your browser's local extension > storage and are sent only directly to the provider you choose — never to us. > > Undo works exactly like any other edit (Ctrl+Z) if you don't like the result.
