Meet Siti — your private AI assistant for Mac, running entirely on your device.
Siti is a profoundly capable, profoundly personal assistant that never sends your words to the cloud.

ASK SITI ANYTHING - Get clear answers to everyday questions - Draft emails, documents, and posts - Brainstorm ideas and make plans - Summarize long text in seconds - Translate between languages - Get help with writing, editing, and code - Explain difficult topics simply - Learn something new, one question at a time

PRIVATE BY DESIGN Unlike assistants that send your data to cloud servers, Siti runs entirely on your Mac. No account, no sign-in, no cloud processing, no tracking, no data collection. Your conversations never leave your computer.
