Automations & dashboards
From answering questions to doing the work
A person no longer has to ask. A trigger starts the work, inside the same permissions and the same audit log as everything else. Automations and live dashboards ship on the Black plan.
Automations
Schedules trigger real LangChain work end to end.
A schedule fires, fetches LangChain sessions, drafts a digest, and waits for approval before posting.
