Free desktop app for macOS, Windows and Linux. Select text, press hotkey, get a structured Claude prompt. Works in Notion, Cursor, Figma — anywhere you type.
Fair question for any "AI tool": where do my text and my key actually go? With Prompt Enhancer there's no backend of mine in the loop. You bring your own Claude API key, it lives in your OS keychain, and your selected text goes straight from your machine to Anthropic. I never see either one. I keep going back and forth on whether to also offer a hosted version so I'm curious: is bring-your-own-key a dealbreaker for you, or the whole reason you'd trust it?
Quick feature I'd love feedback on: the preset system.
Right now there are four Default, Concise, Verbose, and Code so the same hotkey restructures your text differently depending on what you're doing. Writing a commit message vs. drafting a spec need very different prompt shapes.
I kept firing off lazy one-liners like "fix the auth bug" and then spending minutes re-explaining what I actually meant. The problem was never the model it was my prompt structure. But manually writing role / context / task / output every time, in every app, is tedious enough that nobody does it.

Hey Product Hunt 👋
I kept writing lazy one-line prompts ("fix the auth bug") and then losing minutes re-explaining what I actually wanted. The fix isn't a smarter model — it's better prompt structure. But doing that by hand every time, in every app, is tedious. So nobody does it.
Prompt Enhancer is a tiny desktop app: select any text, press a hotkey (⌃⌥⌘P / Ctrl+Alt+P), and it's replaced in place with a structured prompt (role / context / task / output format) the way Anthropic's docs recommend. Under 4 seconds, no copy-paste, no second tab.

macOS native Swift, Windows Tauri/Rust
Works anywhere: Claude, ChatGPT, Cursor, Notion, Figma…
Free to try, free forever with your own key
Would love feedback on the preset system (Default / Concise / Verbose / Code) and where the restructuring helps vs. gets in the way. AMA!
