Small models. Right where your data is.
The AI inside Orbit's apps doesn't need your data on our servers to be useful. Each feature is a small model trained for one job. Most run on your device, shipped inside the app, so your encrypted mail and passwords stay encrypted and the answer arrives before you notice it was asked; the one that decides how loudly new mail should notify you runs on our server, from the sender and subject only. Chatting with Orbit AI is different: big models answer in the cloud, and we say exactly where.
Built for one job
Not a chatbot that tries everything. A model that sorts mail only sorts mail, and is very good at it.
On your device first
Shipped inside the app, run where your data already is. No download, no waiting, no upload.
Marked with a sparkle
Anything Orbit AI decided carries a small violet sparkle beside it, so you always know.
Yours to switch off
Show the whole inbox, hear about every email, or turn the field model off in Settings.
What it does
Quiet help in the apps you already use.

The numbers
Measured on real data the models never saw.
Each model is trained on synthetic examples from invented companies, then tested on hand-written ones from the real world that it never trained on. These are those results, as published with each model.

How they work
A few dozen features, one table, an answer.
The inbox model turns a message's subject and sender into features: each word of the subject and each pair of words, the sender's name, the sender's domain and the shape of the address. It looks each one up among the 16,384 it learned, with weights stored as 8-bit numbers, and adds them up into a score for every kind of mail.
Orbit Pass's field model does the same with a form field: its label, placeholder, attributes, nearby text and the shape of its form, against 8,192 features and 23 kinds of field.

How we build them
No customer data, and the same answer everywhere.
- 1
Synthetic training data
Tens of thousands of examples from invented companies, in many languages. No customer's mail or form ever trains a model.
- 2
A real-world exam
A hand-written test set from real companies and real sites, kept out of training, so the score means something.
- 3
One model, every platform
The web and the desktop apps run the same weights, and tests check they reach the same answer.
- 4
A published report
Every model ships with its size, speed, accuracy and mistakes written down, like the numbers on this page.
When AI runs in the cloud
Where a hosted model is used, and what it sees.
Some jobs need a large model or have to happen before your device has the data. In each case it sees as little as the job allows.
- Orbit AI conversations
- What you ask, with the conversation so far, goes through OpenRouter to the one provider the model you pick is pinned to, and is never passed to another. We never train on it; what the provider logs is set by its own terms. Where your AI chats go
- @Orbit AI in Chat
- Only the one message that mentions it, which its sender chose to send. Not the conversation, its files or its members, and neither question nor answer is stored.
- Mail notifications
- The sender and subject of new mail, which our server can already see. The sealed body never takes part, and the category isn't stored.
- Computer use, in Auto
- A small model reviews each step against your latest request, and nothing else: not the pages read or the output of commands, where instructions planted for an AI would hide.
AI that knows its place.
