BobBrain - On-device AI

BobBrain runs Google's latest Gemma 4 language model entirely on your phone. No cloud round-trips, no data leaves the device for inference, and replies start streaming in milliseconds.

WHY ON-DEVICE
• Privacy: your conversations, voice notes, and images stay on your phone — never uploaded for inference
• Speed: token streaming starts almost instantly, no network latency
• Works offline: full AI assistant in airplane mode, on the metro, or on a flight
• One model, every BOB app: download Gemma 4 once and let other BOB apps share it (saves storage)

WHAT YOU CAN DO
• Chat with Gemma 4 by text, voice, or image — fully multimodal
• Send long voice notes — BobBrain transcribes and replies on-device
• Ask about photos you share — the model genuinely sees them
• Keep multiple conversations going; history is stored privately on your phone
