Social Media Agent is an open-source project from the LangChain team, published on GitHub. It is built to source material worth sharing, curate it into social media posts and then queue those posts for publishing.
A key idea is keeping a person in the loop: the agent prepares drafts, but a human reviews and approves them before anything goes live. Because it is a code repository rather than a hosted app, it suits developers who are comfortable setting up and running agent projects themselves.
