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.
The pricing question always comes up, so let me be upfront: Prompt Enhancer is free forever if you bring your own Claude API key.
No subscription, no per-prompt markup, no account wall. Your key lives in your OS keychain, and your text goes straight to Anthropic nothing routes through our servers. You pay Anthropic directly for what you actually use (usually fractions of a cent per prompt).
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.
One thing I'm proud of: Prompt Enhancer works anywhere you type Claude, ChatGPT, Cursor, Notion, Figma, your terminal, an email draft. No integrations to set up, no copy-pasting into a separate web app.
It's a native desktop tool (Swift on macOS, Tauri/Rust on Windows), so the hotkey just works system-wide. Highlight, press, done.

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.

Would love feedback on the preset system (Default / Concise / Verbose / Code) and where the restructuring helps vs. gets in the way. AMA!
