MobileAI
For Android · US$9.99, once
An assistant that runs an AI language model on your phone itself — and does things with it. Set a timer, call a contact, check your calendar, pause the music, by voice or by typing. No server, so it keeps working in airplane mode.
Read this before buying. The AI runs on your phone, so the phone needs 4 GB of RAM or more, and the first use downloads a 1–5 GB model (Wi-Fi recommended). On a phone with less memory no model will load. Answers come from a small model: good for everyday help, not a replacement for a large cloud assistant.
It does things, not just chat
Ask for a timer and a timer is set. Ask what is on your calendar and it reads your calendar — on the phone, without sending it anywhere.
Phone actions
Timers and alarms, calls (it opens the dialer for you to confirm), calendar events, music and video controls, navigation, flashlight, settings — and the apps you add yourself.
Ask MobileAI from any app
Select text in a browser or any other app and pick "Ask MobileAI", or share it. Translate, summarize or explain it without copying anything.
Voice in four languages
Speak in Korean, English, Japanese or Chinese, and have answers read aloud. History keeps your chats on the phone so you can continue any of them later.
One purchase, and that is the end of it
Cloud assistants are free because your questions pay for them, or they cost a monthly subscription. This one runs on hardware you already own and is US$9.99, paid once. Google Play converts that into your own currency, so the figure on the store page may not match to the cent.
- No advertising anywhere in the app.
- No subscription and no locked features.
- No account — there is no server to hold one.
Your chats stay on the phone
No analytics and no advertising SDK. Chats, contacts, calendar and notifications are read on the phone and never leave it. The only things that go over the internet are the model you choose to download, from Hugging Face, and a report about a bad answer, if you choose to send one.
Questions
Does it work without an internet connection?
Yes, once a model is downloaded. The first download, 1 to 5 GB depending on the model, needs a connection; after that it works in airplane mode.
Which phones can run it?
Android phones with 4 GB of RAM or more. The app recommends a model for your phone's memory: the smallest needs 4 GB, the recommended one 6 GB, and the largest 12 GB. Larger models write better answers and take longer to reply.
Are my chats sent anywhere?
No. The model runs on the phone and there is no server behind the app. See the privacy policy for exactly what goes over the network and when.
Is there a subscription?
No. One purchase on Google Play, no tiers, no features held back.
How good are the answers?
Good for everyday questions, writing help and translation, but small on-device models make mistakes. Check anything important, and do not rely on answers for medical, legal, financial or safety decisions. Long-press any answer to report it.
What you need
An Android phone with 4 GB of RAM or more, and a Wi-Fi connection for the one-time model download.
