Description (10,000 characters)
Meet Siti — your private AI assistant for Windows, running entirely on your device.
Siti is a profoundly capable, profoundly personal assistant that never sends your words to the cloud. Ask questions, draft documents, brainstorm ideas, summarize text, translate languages, write code, or just talk things through. Every conversation is powered by an on-device AI model that keeps your words completely private.
The name is a playful nod to the voice assistants we all know — but Siti flips the script. Instead of sending your requests to the cloud, everything happens on your own PC. Profoundly personal. Entirely private.
ASK SITI ANYTHING
Siti is a general-purpose assistant that adapts to whatever you need:
- Get clear answers to everyday questions
- Draft emails, documents, messages, and posts
- Brainstorm ideas, names, and plans
- Summarize long articles or notes in seconds
- Translate between languages
- Explain difficult or technical topics in simple terms
- Get help with writing, editing, and proofreading
- Work through code and programming questions
- Learn something new, one question at a time
Whatever you would ask a cloud assistant, you can ask Siti — without your words ever leaving your computer.
100% ON YOUR DEVICE
Siti's AI runs entirely on your Windows PC using an on-device language model. No conversation data is transmitted to external servers. No cloud processing is involved. After a one-time model download (approximately 1-2 GB), Siti works without an internet connection. This means you can use Siti on your laptop during flights, commutes, or anywhere without Wi-Fi — and your conversations stay on your machine.
PRIVATE BY DESIGN
Your privacy is not an afterthought — it is the entire point. Unlike assistants that send everything you type to remote servers, Siti keeps your conversations on your device:
- No account and no sign-in required
- No cloud processing
- No tracking and no ads
- No data collection
- Your conversations never leave your PC
What you say to Siti is yours alone.
WORKS ANYWHERE, ANYTIME
Because everything happens on your device, Siti is always ready — online or offline. On a plane, in a remote cabin, or behind a restrictive firewall, you get fast, private answers wherever you are. No connection, no problem.
