Do I need to learn Mermaid?

No. Arialine writes Mermaid from plain-language descriptions. You can still paste Mermaid, attach a .mmd file, or export the source whenever you want.

Do we need a paid Slack plan?

No. Arialine works on every Slack plan, including Free and Pro. Its /arialine command, mentions and shortcuts are ordinary Slack app features. Only asking Slackbot to use Arialine needs a Slack plan that includes Slackbot (Business+ or Enterprise+).

Where does my data live, and do you train on our conversations?

Diagram renders and canvases live in Slack. Arialine stores the diagram source, versions, decisions, and service/account state needed to keep boards working. Arialine does not use your Slack content to train AI models.

Can I actually undo changes and keep history?

Yes. Every accepted change creates a new version instead of overwriting history. Undo removes a change, Rewind restores an earlier state as a new latest version, and Branch lets you explore an alternative separately.

Does Arialine work on mobile?

Yes. Each diagram version includes a mobile-friendly PNG in Slack, while the interactive HTML version is available when you want the richer view. Versions, decisions, Undo, and Rewind remain available from Slack.

A Slack app that turns plain language or pasted Mermaid into editable, versioned diagrams with full decision history.

Overview

A look at arialine.app

Arialine is a Slack app for creating and evolving diagrams from conversations. Users mention @arialine with a plain-language description or paste Mermaid code to generate interactive diagrams. Teams can edit diagrams in threads by talking to @arialine, with every change creating a new version instead of overwriting previous work. The app maintains a complete decision ledger linking each version to the message that caused it, supports undoing individual changes or rewinding to earlier states, and allows branching into alternative versions. Diagrams can be exported as PNG, SVG, Mermaid source, or PDF, rendered in Slack Canvases, or accessed as interactive HTML files.
