Alter puts AI inside your clipboard. Press ⌥ Space in any macOS app, type a command in plain English, and the transformed text pastes back — before you'd have even found the ChatGPT tab.
psst — ⌥ + Space works on this page too. Try it.

Chrome extensionAlter
The clipboard you're reading about. AI lives one keystroke away from any app — and it's free.
alter ↑Questions you might have.
Is my clipboard sent to a server? +
Only when you press Enter. The text goes from your machine to api.groq.com (the Groq inference API) and the result comes back. Nothing else is logged, stored, or sent anywhere.
How is my API key stored? +
Encrypted via safeStorage, which uses the macOS Keychain. Even other apps on your Mac can't read it.
Does it work offline? +
The UI does, but the AI transform doesn't — it needs Groq's API. (A local-LLM mode via Ollama is on the v2 roadmap.)
Why Groq instead of OpenAI? +
Latency. Groq returns a 70B-parameter response in ~1.5 s. GPT-4o takes 4–8 s. For a clipboard utility, the difference between "instant" and "I'm waiting" defines whether you build the habit.
Is it really free? +
Yes. The app is free and open source (MIT). You bring your own Groq API key — Groq has a generous free tier that covers thousands of transforms per day.
Will there be a Windows / Linux version? +
v1 is macOS-only. Cross-platform is on the roadmap if there's demand. Star the repo to vote.
Why does it ask for Accessibility permission? +
So it can auto-paste the result into the app you came from. If you decline, Alter still copies the result to your clipboard — you just press ⌘V yourself.
