LifeOS
Daniel Miessler's open-source personal AI harness: goal/context storage, intent engineering and verification loops.
Verified against: ourlifeos.ai as of 2026-09-28
Quick verdict: LifeOS is an open-source personal AI harness for goal and context storage, intent engineering and verification loops. It is the right shape if you want a controllable, model-agnostic assistant you run on your own keys and are comfortable maintaining your own stack. It is not a turnkey product: you carry the inference cost and the setup work. It earns a slot in your toolset only if you already have a personal-agent use case large enough to justify the maintenance; for one-off tasks, a hosted assistant is less friction.
