TextPolisher.app
Instant text polish on your Mac. Any app. Zero internet.
TextPolisher lives in your menu bar and rewrites any selected text - Slack, Teams, Mail, Notes, your browser - in one keystroke. Fix grammar or shift tone (professional, friendly, concise) using Apple's on-device AI model. No account, no API key, no cloud. Free.
Hey Product Hunt 👋
I built TextPolisher because I kept pasting messages into ChatGPT/Gemini just to fix grammar or soften my tone before hitting send - and I hated that my half-formed Slack messages were leaving my machine.
TextPolisher fixes that. It sits in your menu bar and polishes whatever text you've selected, in any app:
Select text anywhere → press a shortcut → it's rewritten in place
Choose a style: Fix Grammar, Professional, Friendly, or Concise
Two modes: a quick preview (⌥⌘P) or instant replace with no clicks (⌥⇧⌘P)
Fully customizable shortcuts
The part I care about most: it runs entirely on-device using Apple's built-in Foundation Models. 0 bytes ever leave your Mac. No account, no API key, no subscription. (If you don't have Apple Intelligence, it falls back to a local Ollama model - still 100% local.)
It's free, notarized, and works system-wide. Requirements: macOS 26+.
I'd love your feedback - especially on which writing styles you'd want next. Happy to answer anything in the comments!
