RAI Assistant is a voice-first AI assistant for Android. Flip the Private Memory toggle to switch between blazing ~150 ms cloud voice and full on-device privacy. Built by Aerendir.
Conversational AI built for phones. Voice-first, low-latency, with real privacy controls.
Sub-200 ms round trip in cloud mode via WebRTC + LiveKit. Talk naturally, get answers naturally — no walkie-talkie delays.
Flip Private Memory on and a local LLM takes over with RAG memory. Your conversations never leave your phone.
Hardware-backed proofs that a real human held the device when a message was sent. Anti-replay, anti-spoofing built in.
Wake-word free. Tap to talk, release to send. No "Hey assistant" awkwardness — designed for how people actually talk to phones.
Sign in on any device — your conversation history and memory follow. (Cloud mode only; on-device stays on-device.)
Clear data anytime. Export memory. Toggle voice off. Cancel any time. No dark patterns.
One toggle switches between two completely different modes. Both ship in the same app.
When you want immediate answers from the latest frontier models.
Flip the toggle. Everything runs locally — no audio leaves your phone.
Real privacy comes from infrastructure, not promises.
Liveness proofs are signed by the Android Keystore using StrongBox or TEE — meaning a real human held the device when the proof was generated. Verifiable by recipients without trusting our backend.
The app pins to Amazon's ACM certificate hierarchy. Even with an attacker-installed root certificate, traffic to our backend can't be intercepted.
OAuth scopes for Gmail integration are reviewed under Google's Cloud Application Security Assessment (CASA) Tier 2 — the highest tier for apps requesting restricted user data.
Backend runs in AWS Frankfurt (eu-central-1). Aurora Postgres with encryption at rest. ElastiCache with TLS. Voice via LiveKit on a hardened VPC.
