## Summary

LangChain says its managed Deep Agents can now operate a browser to take actions on sites without an API, such as booking a reservation. The browser also lets an agent test an application end to end through its UI, and a user can take over to sign in before the agent resumes.

Your agent can:
- Take actions on sites with no API, like booking a reservation
- Test an application end to end through its UI
- Hand you the browser to sign in, then pick up where it left off
