About

Arialine is an AI diagram generator and Mermaid diagram editor built for engineering and product teams working in Slack. Create flowcharts, architecture diagrams, sequence diagrams, UML, ERD, C4, swimlanes and other technical diagrams from plain language, Slack discussions, or Mermaid code. Paste valid Mermaid with /arialine and it renders without AI or usage limits. Diagrams stay editable in their Slack thread: reply to make changes, with every accepted edit saved as a version linked to the source message. Arialine includes history, undo, rewind, branching, decision context, PNG/SVG/PDF/.mmd exports, interactive HTML diagrams, Markdown-to-Slack-Canvas rendering, Mermaid 12 + ZenUML support, and an MCP server for Slack AI. It works on every Slack plan, including Free.

About

The most powerful development environment, now adapted for writing documentation. Use a single authoring environment, eliminating the need for a wide array of tools. With the built-in Git UI, an integrated build tool, automated tests, and a ready-to-use and customizable layout, you can focus on what matters most, your content. You can now combine the advantages of Markdown with those of semantic markup. Stick to one format, or enrich markdown with semantic attributes and elements, Mermaid diagrams, and LaTeX math formulas. Ensure documentation quality and integrity with 100+ on-the-fly inspections in the editor as well as tests in live preview and during build. The preview shows the docs exactly as your readers will see them. Preview a single page in the IDE, or open the entire help website in your browser without running the build. Reuse anything, from smaller content chunks to entire topics or sections of your TOC.
