I built LifeContext AI because I wanted an AI that truly knows me — without sending my most private thoughts to someone else's server. The problem: every AI companion (Replika-style) uploads your conversations to the cloud. That felt wrong for something you confide in daily. So I asked: can a genuinely personal AI run 100% on a phone? Turns out, yes — but it was brutal. I spent months fighting: - GPU crashes on Android (Vulkan kept dying on Adreno chips) - 0.24 tokens/sec speeds that made chat unusable - small models that "leaked" their own system prompt The breakthrough was forcing CPU-only with KleidiAI optimizations, which took responses from ~40s to ~15s, and rewriting the system prompt so the model stopped repeating rules and started feeling human. What makes it different: - No account, no server, no telemetry. Airplane mode works. - One-time model download (~1.3 GB free, 2.7 GB Pro) - Persistent memory across sessions, fully on-device - Voice in/out, 9 languages The free tier is genuinely free — no ads, no forced signup. I'd love your honest feedback: what would make an offline AI companion useful to YOU? I'm in the comments all day. 🙌
