Project-Based Agents
Last week, we highlighted that we would soon release project-based agents. You will be able to set this up when creating a new project by selecting the Agent Coordinator option, giving you a dedicated AI teammate that knows the content, takes on work and keeps things moving, even when you are offline. Your AI teammate can analyze project data, build internal dashboards or prepare documents, using data from the project.
