A lightweight AI overlay for Mac that screen sharing can't see. Hit a hotkey to screenshot anything on your screen and get the answer back. Feed it your CV and a job posting and the answers match your background, not a textbook. Ask follow-ups in the chat layer. Set sticky notes only you can read. Transcribe an audio call as it happens. Zoom, Meet and Teams can't see any of it. Hidini also supports BYOK and local AI. Fast, built with Native Swift, under 4 MB. Free to try, no subscription!
