OpenHuman just hit #1 on GitHub Trending with 1,595 stars in one day. It is an open-source personal AI agent written in Rust — think Limitless or Friend, but local-first, self-hosted, and built on a stranger memory architecture.
What OpenHuman actually does
Every 20 minutes it pulls your inbox, calendar, repos, docs and messages, compresses them, and feeds them into a memory holding up to 1 billion tokens. It connects to 118+ services out of the box. On your desktop it ships as a mascot that can join Google Meet as a real participant. Workflow data stays encrypted on your machine and never leaves.
TokenJuice and why it matters
The trick is TokenJuice, a compression layer between tool calls and the LLM. Every tool result gets compressed before it hits the model — the project claims an 80% cut in cost and latency. That is the moat. Limitless and Friend are cloud-bound; OpenHuman runs on your laptop and still keeps a 1B-token context usable.
Self-hosting and developer use
It is a Rust crate you clone and run, exposing audio, video and desktop interaction. Plug new connectors into the 118+ list or wire your own agent on top. No API key — your machine is the API.
