Claims & capabilities
Imagine your agent never asks the same question twice. Until now, most agents have been stateless . Each conversation resets to zero, forgetting what users said just minutes ago or weeks ago. Developers tried to bridge this gap with homegrown solutions — storing embeddings in databases, manually retrieving prior messages, or stuffing entire chat histories into prompts. These workarounds add latency, cost, and complexity, and still fall short of delivering truly personal, context-aware interactions.
