What you can do with it
The on-phone AI understands text and images, so it's useful for everyday work you'd rather keep to yourself.
- Ask questions and get answers, with no network at all.
- Describe a photo, or read the text inside one.
- Explain a chart in plain words.
- Ask about a document: text, code, or a PDF with a text layer.
Privacy enforced by a test, not a promise
Plenty of apps say your data stays private. MOZGII checks it every time the app is built: the build fails if the AI's code makes any network call other than downloading the model itself.
The only thing the server ever hears about it is a daily count of messages, photos and documents, so you can see your own usage. The server rejects any other field.
How it gets onto your phone
The model is about 1.6 GB and downloads once, after you install the app. The download can pause and resume, and it's checked against a fingerprint, so a damaged file is deleted rather than loaded. You choose whether to download over mobile data or wait for Wi-Fi.
It needs a phone with at least 6 GB of memory, such as iPhone 12 Pro or iPhone 14 and later. The app checks your phone first and tells you plainly if it can't run the model.
Why it matters for your work
Contracts, invoices, medical letters, client photos: a lot of business material shouldn't be pasted into an online chatbot. With an AI that never leaves the phone, you can still get help with it.
It also works where the network doesn't: on a plane, in a basement workshop, abroad without roaming. And because it runs on your device, it costs nothing per question.
When you do want the online AI
MOZGII also has an online AI helper for summaries, reply drafts, plain explanations, ideas and a scam check. Before anything you type reaches a cloud AI, the app asks. Say no and nothing is sent, and you can keep using the private one instead.
An everyday example
Maya is on a flight and photographs a supplier's contract. She asks the on-phone AI what clause 7 means in plain words. The answer appears in seconds, and neither the photo nor the question ever left her phone.
