Zephr is a macOS menu bar app that rewrites and fixes your text instantly — in any app, any language. Select text, press ⌃R to rewrite or ⌃E for a custom prompt. Text is replaced in-place with formatting preserved.








Hey everyone! 👋 I'm Derek, the maker of Zephr.
I built this because I work across multiple languages daily and got tired of constantly switching between apps just to fix, translate, or polish text. I wanted something that works right where I'm already typing — no copy-pasting into ChatGPT or Claude, etc..
With Zephr, you just select text in any app, hit ⌃R to rewrite or ⌃E to give a custom prompt (like "translate to English" or "make it more formal"), and it replaces your text in-place.
What makes it different:
Works system-wide in any macOS app
Preserves rich text formatting (bold, italic, etc.)
BYOK — supports 12+ providers (OpenAI, Claude, Gemini, etc.)
You can even use CLI with your existing subscription — free AI rewrites if you already pay for an API plan
I'd love to hear your feedback. What features would you want to see next?
