Built to answer fast

Aha times every model on your Mac and sends your request to the quickest healthy one. Reasoning is switched off and the reply streams straight in.

It knows where you are…

Reads the room

Chat, email, search, issue trackers, AI prompts, even the terminal. Aha sees which app and page you’re in, so a commit message stays short and an email stays warm.

Paste, but smarter
⌃⌘V

Smart Paste

Pastes your clipboard shaped for the field: bullets in chat, a short query in search, links without tracking junk.

Your details stay yours

Field Assist sends placeholders, not your name or address, and Aha fills in the real values locally. Nothing leaves until you press the shortcut.
