What Arialine does

Arialine turns Slack discussions into living, versioned diagrams. You describe a system or process in normal language and Arialine creates a Mermaid-based diagram in Slack. Each accepted change creates a new version instead of overwriting history.

Every board keeps the diagram, its source, version history, and a decision ledger connected to the Slack messages that caused changes. You can ask why an element exists, rewind to an earlier version, undo a change, branch an alternative, brainstorm approaches, and export the result.

Arialine also renders Markdown into native Slack Canvas documents and exposes an MCP server so Slack's built-in assistant can create and edit diagrams.
