Developer u/Roy3838 demonstrates "Observer," an open-source, fully local AI agent for iOS and Android that uses on-device models to monitor real-world events via phone cameras. The system triggers custom alerts — such as images via Telegram or phone calls — for specific detected scenarios including unauthorized car approaches, bird nest activity, washing machine cycles, pet feeding, and gym equipment availability. This showcases practical edge inference for personalized, privacy-preserving automation without cloud dependency.
