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

Legivel converts Markdown into book-style PDF documents for developers, product teams, writers and AI agents. Users can create PDFs in a browser-based editor with a side-by-side preview, or send Markdown to the HTTP API or MCP server. The renderer supports GitHub-style tables, task lists, footnotes and alerts, as well as Mermaid diagrams, LaTeX mathematics, code blocks, SVG graphics, barcodes and QR codes. Output PDFs can include a contents page with page numbers, bookmarks, embedded fonts, selectable and searchable text, clickable links, repeated table headers, and vector-rendered diagrams and equations. Common uses include producing reports, technical documentation, invoices, handbooks, papers and correspondence. A free plan includes up to 100 documents per month; paid plans increase the monthly document allowance.
