Agent Builder is now LangSmith Fleet. All existing agents, configurations, and integrations continue to work. No action is required.
LangSmith Fleet is a no-code platform for creating and managing AI agents. It allows you to create agents from templates, connect your accounts, and let the agent handle routine work while you stay in control. Use Fleet to:
  • Automate everyday tasks like drafting emails, summarizing updates, and organizing information.
  • Connect your favorite apps to bring context into your agent’s work.
  • Use in chat or where you work (e.g., Slack) to get help in the flow.
  • Stay in control with simple approvals for important actions.
