NIDO: A Fully Offline Phone AI Assistant That Works in Airplane Mode

NIDO_007 · reddit · 2026-11-08

A Reddit developer unveiled NIDO, an AI assistant that runs entirely on-device via llama.cpp — no account, no cloud, no subscription, fully functional in airplane mode.

Key capabilities

Offline chat + local memory: encrypted database for notes and reminders, cross-language retrieval (ask in Spanish about English-saved notes), optional 8:00 AM daily summary
Acts on requests: reminders, calendar events, conversions — anything with external effects requires explicit user confirmation; pasted text is never treated as commands
On-device document QA: txt/md/csv/json/pdf/photos indexed locally
Offline knowledge packs: 174 verified first aid/disaster/survival guides, an optional 50,000-article Wikipedia pack, emergency numbers for 69 countries; answers distinguish source sentences from model output
Serverless messaging: Bluetooth end-to-end encrypted chat between devices, with encrypted store-and-forward relaying through mutual contacts; ML-KEM-768 post-quantum crypto, Double Ratchet, 3-second panic wipe
CPR training: voice-read guide, 110 compressions/minute metronome, camera-based rate feedback

Quality data: 202/202 retrieval checks passed against 2025 first aid guidelines; 6,286 automated tests all passing; UI in English, Spanish, and Portuguese.
