Meet Siti AI — your private AI assistant that runs 100% on iPhone. Ask anything, fully offline. No cloud, no account, no tracking. Profoundly personal and private.

Meet Siti — your private AI assistant, running entirely on your device.

Siti is a profoundly capable, profoundly personal assistant that never sends your words to the cloud. Ask questions, draft messages, brainstorm ideas, summarize text, translate languages, or just talk things through — all powered by an on-device AI model that keeps every conversation completely private.

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

100% ON YOUR DEVICE Siti's AI runs entirely on your iPhone and iPad. No data is ever sent to a server — your conversations never leave your device. After a one-time model download (~1–2 GB), Siti works completely offline. No internet connection required.

PRIVATE BY DESIGN • No account, no sign-in • No cloud processing • No tracking, no ads • No data collection Your conversations are yours alone.

WORKS ANYWHERE, ANYTIME On a plane, on the subway, off the grid — Siti is always ready. Because everything happens on your device, you get fast, private answers wherever you are.

FAST AND NATIVE Built as a native app and optimized for Apple silicon, Siti delivers quick, fluid responses that feel right at home on iOS.

WHY SITI? The name is a playful nod to the assistants we all know — but Siti flips the script: instead of the cloud, everything stays with you. Profoundly personal. Entirely private.
