See it work in airplane mode
A real, unedited screen recording on an Android phone. Airplane mode is on, Wi-Fi is off, and Zemith Offline translates a Japanese lunch menu from a photo.
Turn on airplane mode and switch Wi-Fi off. The phone has no connection at all.
Pick Zemith Offline in the model picker. It runs on the phone, with no internet, and is free.
Attach a photo of a menu written in Japanese and ask: "translate this menu for me".
The model reads the photo and lists every dish in English with its price, all on the phone.

A capable model needs a recent chip and enough memory. Here is what Zemith Offline needs as of November 2026.

What people use offline AI for
Translate this menu for me and tell me which dishes have pork.
Translate a menu or sign abroad
No roaming data? Take a photo of the menu and ask for a translation. The model reads the photo on the phone.
Turn these bullet points into a short, friendly email to my team.
Get work done on a flight

I'm deciding between two job offers. Ask me questions until it's clear which one fits me.
Talk it through where there is no signal
Start offline Live on a hike, in the car or in a basement and think out loud. You can interrupt it, like a phone call.

Questions, answered
Is there an AI app that works without internet?
Yes. Zemith Offline runs an AI model on your phone, so chat, photo questions and spoken conversations work in airplane mode. You need internet once to download the model; after that, no connection is needed.
Is Zemith Offline free?
Yes. Offline chat and offline Live are free on every plan, use no credits and need no account. A paid plan only matters for the cloud models you use when you're online.
Which phones can run Zemith Offline?
Offline chat needs an iPhone with an A14 chip or newer on iOS 16.4 or later, or a 64-bit Android phone with about 6 GB of RAM or more and a fast processor. Offline Live voice needs an iPhone with an A15 chip or newer, or an Android flagship such as a Pixel 8 or 9 or a Snapdragon 8 Gen 1 phone. The app checks your phone before it offers the download.
How big is the download?
About 1.4 GB on iPhone. On Android the download is about 2.9 GB and the first start unpacks about 4.9 GB more, so keep around 8 GB free. You download it once, over Wi-Fi if you like, and chat and Live share it.
Are my offline chats private?
Yes. Offline chats, photos and your instructions are stored only on your phone and never sent to Zemith's servers. Deleting the app deletes them.
What can't Zemith do offline?
Offline mode has no web search, files, plugins, image generation or model switching, and takes up to 3 photos per chat. A phone-sized model also knows less than the top cloud models. On iPhone, an answer stops if you leave the app. Online, the same app gives you GPT, Claude, Gemini and the other cloud models.
