About Plain
Plain turns Sidekick from a drafting assistant into an agent that acts
Plain is a customer-support platform building an agentic layer — 'Sidekick' — into the core thread workflow. Recent releases moved Sidekick from suggesting to acting: it can take actions across connected tools, start working proactively the moment a thread matches a workflow, and it now answers in Slack. The surrounding plumbing (scheduled workflows, thread fields via the chat widget, machine-user API links to Linear) is all in service of more automation.
