How it stays private →
Everything stays on your computer
A real assistant, small enough to live on an ordinary laptop's processor.
-
Private by design
Your chats, images and voice never leave your computer. We couldn't read them if we wanted to.
-
Works offline
Once a model is on your computer, ChatNano doesn't need the internet at all.
-
Talk to it
Voice calls with live captions, heard and spoken on your own machine.
-
Show it a picture
Attach or paste a photo and ask about it. It starts looking while you're still typing.
-
Thinks it through
Replies can reason step by step first. Open the arrow above an answer to read how it got there.
-
Fast on a laptop
Its own engine, written from scratch for ordinary processors. No graphics card needed.

Questions
What do I need to run it?
A Windows laptop or desktop. ChatNano runs on the processor, so you don't need a graphics card. Nano Tokyo needs about 0.5 GB of free memory; the bigger models need more.
Is it as good as ChatGPT?
No. ChatNano's models are tiny next to cloud AI, so they know less and make more mistakes. In return, everything happens on your computer, it works offline, and it's private. Check anything that matters.
Does it work without the internet?
Yes. Once a model is downloaded, chats, voice calls and pictures all work offline.
What happens to my chats?
They're saved on your computer, and nowhere else. You can delete a chat by right-clicking it in the sidebar.
When can I get it?
ChatNano is coming soon to Windows. Write to hello@estience.com if you'd like to hear when it's out.
