Agent Inbox is a user interface created by LangChain. It gives people an inbox-style view where agents can surface tasks, drafts and questions that need a human decision.
Listed here as an AI email assistant, it fits workflows where an agent handles messages and you step in to approve or adjust its work. The public page offers little detail beyond that, so it is mainly useful for developers already building with LangChain who want a simple way to supervise their agents.
