BIT

BIT — Your Private, Offline AI Engine

BIT is a fully offline, privacy-first AI engine built from the ground up for Android. No cloud. No data leaves your device. Every model, every conversation, every document you search stays local — running entirely on your phone's silicon.

ON-DEVICE LLMs

Run quantized Llama, Qwen, Gemma, and Mistral models directly on your device via native C++ inference bindings — no internet connection required, ever.

OFFLINE VOICE PIPELINE

Talk to BIT naturally with fully local speech recognition and neural voice synthesis. Smart voice-activity detection lets you interrupt mid-response, just like a real conversation — all processed on-device.

RELIABLE TOOL CALLING

BIT uses grammar-constrained decoding to guarantee valid, structured tool calls every time — no malformed outputs, no broken function calls, even on small on-device models.

MEMORY VAULT & LOCAL DOCUMENT SEARCH

BIT remembers your preferences across sessions with a decaying memory model that mimics natural recall. Search your own documents instantly with hybrid retrieval that combines semantic vector search with keyword matching — all indexed and queried locally.

BUILT-IN MODEL STORE

Browse, download, and switch between quantized open-source models directly within the app. Try different models and pick what works best for your device and needs.

100% PRIVATE, 100% OFFLINE

BIT is engineered with zero network dependency by design. All inference, speech processing, and document indexing happen entirely on your device. Your data is yours — always.
