Private AI

Private AI for Android.

A private AI chatbot that runs on your phone, not in someone else's cloud. LlamaBox keeps prompts, answers, and history on-device.

What is private AI on Android?

Private AI on Android means the large language model runs inference directly on your phone. Your prompts, generated answers, and chat history never leave the device. There is no cloud API call, no vendor retention policy, and no account graph to trust.

Why local beats cloud "private mode"

Many chatbots offer a "private mode," but that usually means the vendor promises not to train on your data. The prompts still travel to a server, are subject to subpoenas and breaches, and rely on a privacy policy you cannot verify. LlamaBox removes the server from the path entirely.

Cloud private mode: data is encrypted in transit and stored under a vendor policy.
LlamaBox local AI: the local chat path does not use a LlamaBox server. Network features are separate.

FAQ

What is private AI on Android?

Private AI on Android means the language model runs inference directly on your phone instead of sending prompts to a vendor server. Local chat inference does not send prompts or responses to a LlamaBox server.

Is LlamaBox a private AI chatbot for Android?

Yes. LlamaBox loads a quantized GGUF model into app memory and runs it on the phone CPU. There is no cloud inference endpoint, account, or telemetry.

How is local AI more private than cloud 'private mode'?

Cloud 'private mode' still sends tokens to a server with retention policies and subprocessors. Local AI removes the server from the chat path entirely.

Can private AI work offline?

Yes. Once a model is downloaded, LlamaBox works in airplane mode. For the local chat path, both follow from on-device inference; network features are separate.

What models can I use with LlamaBox?

any compatible GGUF model that fits your phone's RAM. Start with small Q4_K_M quantizations (0.5B–3B class) and scale up on devices with more memory.

Is LlamaBox open source?

The app source is not yet public; an AGPL-3.0 source release is planned. A separate commercial license is available for proprietary use.
