Offline chat

Offline AI chat on Android.

Chat with a local language model even when the network is off. LlamaBox keeps every conversation on your phone.

What is offline AI chat?

Offline AI chat means having a conversation with a language model without an internet connection. The model file lives on your phone, and every token is generated locally by the CPU. Once the model is downloaded, you can chat in airplane mode, underground, abroad, or anywhere the network does not reach.

Why offline AI chat matters

Most chatbots stop working the moment you lose signal. Offline AI chat keeps working. That matters for:

Travel and flights — useful AI in airplane mode
Remote and field work — no dependency on mobile data
Low-connectivity regions — reliable access where networks are weak
Privacy-sensitive situations — the local chat path does not use a LlamaBox server
Battery and cost — no continuous cloud round-trips

How LlamaBox runs offline AI chat

Download a GGUF model over Wi-Fi, then disconnect
LlamaBox loads the model into app memory
Inference runs via llama.cpp on the phone CPU
Prompts and answers are generated locally with no network call
Chat history is stored in a local SQLite database

Offline AI chat vs cloud chat

Proving it works offline

The easiest test: download a small model, enable airplane mode, and start a chat. LlamaBox will keep answering because the model is on the phone. No trick, no cached response — live local inference.
