The whiteboard alternative that lives in Slack

Miro and Lucidchart Slack apps mostly do one thing: post a link that takes your team out of Slack. Arialine is different — the diagram is created, edited, versioned, and stored inside the Slack thread where the discussion is happening. No new tool to license, learn, or log into.

What link-out whiteboards cost you

Every diagram review starts with 'can everyone access the board?'
The discussion happens in Slack, the artifact lives elsewhere — so the artifact rots.
Per-seat whiteboard licenses for people who touch a diagram twice a quarter.
When the board owner leaves, the board dies with their account.

How Arialine replaces the whiteboard workflow

Diagrams where decisions happen

Describe the system in the channel where you're already discussing it. The diagram posts into the thread; edits are replies. Nobody context-switches.

Team-editable by default

Anyone in the thread can propose or apply changes (gated by per-channel edit modes). There is no single file owner to bottleneck on.

Versioned, not overwritten

Every change is a new version with an author and a reason. Undo, Rewind, Revert, and Branch are built in — like git for diagrams, but usable by anyone.

Nothing leaves Slack

Diagrams are Slack files; the decision ledger is a Slack Canvas. Your security review is 'it's Slack', not a new vendor assessment.

Frequently asked

Can Arialine replace Miro completely?+

For freeform sticky-note workshops, no — Miro is great at that. For system diagrams, flows, and architecture that evolve with discussion, Arialine keeps the artifact where the discussion is, which is what keeps it current.

How is this different from the Lucidchart Slack app?+

Lucidchart's integration shares links to diagrams that live in Lucidchart. Arialine's diagrams are created and stored in Slack itself — no external account required for anyone on the team.

What diagram types can it draw?+

Anything Mermaid supports: flowcharts, sequence diagrams, state machines, ER diagrams, class diagrams, and more — generated from plain language.
