LifeContext AI
An AI companion that works in airplane mode
LifeContext AI is an AI companion for Android — chat, voice, and memory — that runs entirely on your phone. No account, no server, no telemetry. Download a model once (~1.3-3 GB), then use it anywhere, even in airplane mode. Your conversations never leave your device.
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. 🙌
