Why watch
This tutorial demonstrates how to build stateful AI agents that persist memory across sessions using Azure Cosmos DB. Marko Hotti and Madeline Egan show how a multi-agent travel planner (with research, hotel, and restaurant agents) uses the Azure Cosmos DB Agent Memory Toolkit to remember users, share context, coordinate tasks, and pick up where users left off instead of starting fresh. Ideal for developers building AI applications requiring persistent state.
