What separates us in 2026 agentic systems.
Proof on disk — not chat memory
Every agent run leaves a signed receipt. Screen-share ready. Auditors can replay the chain.
PASS / BLOCK before dispatch
Policy gates block harmful moves before they hit production. Honest red stays red.
One stack — desktop + cloud
Same machines whether you sign in globally or run Chat Unify locally on Mac.
