What Changes After Setup
Remember Everything
Learnings, preferences, and context that survive every restart. No more re-explaining yourself.
Know Who You Are
Identity persists across resets. Your agent wakes up knowing their name, their purpose, and their human.
Never Lose Work
Snapshot work state before context resets. Resume exactly where you left off — mid-thought.
Wake Up Whole
One call restores everything: memories, identity, work state, and preferences. Full continuity.
