I’ve been experimenting with a different direction for personal AI:
not cloud chatbots,
not another wrapper,
but a local-first cognitive operating system.
So I built EIDOLON OS.
An experimental AI system that combines memory, vision, semantic retrieval, CCTV intelligence, workflow replay, and local agent actions into one modular platform.
A local-first AI cognitive operating system designed to transform raw desktop activity into structured, searchable memory.

EIDOLON can analyze uploaded videos and camera feeds using local computer vision pipelines.
Features include:

The system also includes a local action/agent layer capable of:

Built with:
Everything runs locally.
No cloud dependency.
No telemetry.
No external memory APIs.
Most AI systems today are stateless chat interfaces.
I wanted to explore something different:
an AI system that continuously remembers, observes, structures, and retrieves contextual information like a cognitive layer for the machine itself.
Still early.
But the foundation is becoming real.
