Changelog

Workflow steps with our Internal Agent can call your own MCP tools, you can run a manual workflow across a whole queue at once, and our Customer Agent now closes completed threads.

Broadcasts now live in Plain, in the left sidebar, with the same login and permissions as everything else.

Grow and improve your knowledge base from what customers actually asked.

Five other updates: a thread sidebar you arrange yourself, alerts when a webhook fails, users managed from your identity directory, and two things Ari now knows.

New Plain workspaces now start with label suggestions, teammate suggestions via Slack, and test threads already in place.

While you could already link a GitHub pull request to a thread, you can now do so by pasting the full link into the search bar.

You can now create more than one business hours schedule in your workspace, each with its own name, timezone, and working hours.

Sidekick discussions now render markdown in full, headings included.

Machine users can now reply as one of your teammates in Slack, email, and the timeline messages.

Three changes to Ari, our Customer Agent: it now asks clarifying questions to vague messages, you control whether it hands off when a customer tags a teammate, and custom instructions can be longer.
