Use cases

One app, many jobs.

Arialine handles the whole diagram lifecycle inside Slack. Pick the job you're hiring it for.

Render Mermaid diagrams directly in Slack

Paste Mermaid code or a .mmd file into Slack and get a rendered diagram back in the thread — as an interactive HTML file plus a PNG. No external tools.

Turn Markdown files into native Slack Canvases

Share a .md file in Slack and get a native Slack Canvas — headings, lists, tables, and every mermaid code block rendered as an embedded diagram.

Generate diagrams from plain language, inside Slack

Describe a system in plain language and get a rendered diagram in the Slack thread. Talk to @arialine to edit it. Every change is versioned with full history.

Interactive, zoomable diagrams as Slack files

Arialine posts diagrams as interactive HTML files in Slack — pan, zoom, and inspect on desktop, with a PNG fallback everywhere else.

The whiteboard alternative that lives in Slack

Skip the external whiteboard. Arialine creates and evolves diagrams inside Slack threads — no separate app, no logins, no stale boards.

Decision records that write themselves

Arialine keeps a decision ledger for every diagram — each change quoted, dated, and linked to the Slack message that caused it. ADRs without the ceremony.

Git-style version control for diagrams, no git required

Version history, undo, rewind, and branching for diagrams — inside Slack. Every change tracked with author and reason, nothing ever overwritten.
