Free and Team plans

Arialine Free includes every feature. Its limits are per workspace: 3 boards, up to 8 versions on each board (v1 to v8), and 10 AI generations per day (UTC). Pasted Mermaid never uses AI, so it renders without limit: once the 3 boards are in use, pasted Mermaid is posted as a one-off render that isn't saved as a board.

When a board reaches v8 on Free, it stays fully readable: history, decisions, source and exports keep working. New edits, proposals, Undo and Rewind on that board need Team. A branch creates a new board and counts toward the 3 boards. Boards that went past v8 on Team keep all their versions if the workspace returns to Free; they only stop accepting new ones.

Arialine Team removes every limit and renders PNGs at high resolution (twice the pixel size), so large diagrams stay sharp. SVG exports and the interactive HTML file are sharp on both plans. Pricing is flat per Slack workspace: $50/month or $600/year, independent of member count.

Billing and entitlement are workspace-scoped, including workspaces inside Enterprise Grid.

Arialine works on every Slack plan, including Slack Free and Pro. You do not need Slack Business+ or Slackbot to create and edit diagrams; the /arialine command, mentions and shortcuts are ordinary Slack app features. Arialine is not priced per seat: the Team price is the same for five or five hundred members.
