Description
Arialine serves as an AI-driven diagram generator and Mermaid diagram editor specifically designed for engineering and product teams utilizing Slack. It allows users to create a variety of technical diagrams, including flowcharts, architecture diagrams, sequence diagrams, UML, ERD, C4, and swimlanes, using plain language, discussions from Slack, or Mermaid code. By simply pasting valid Mermaid code with the command /arialine, users can render diagrams without any AI limitations or usage restrictions. These diagrams remain editable within their original Slack threads, enabling team members to respond and make adjustments, with every approved modification recorded as a version linked to the originating message. Additionally, Arialine boasts features such as history tracking, undo options, rewind functionality, branching capabilities, decision context, as well as various export formats like PNG, SVG, PDF, and .mmd. It also supports interactive HTML diagrams, Markdown-to-Slack-Canvas rendering, and is compatible with Mermaid 12 and ZenUML, alongside providing an MCP server for Slack AI integration. Notably, Arialine is accessible across all Slack plans, including the Free tier, ensuring that everyone can leverage its capabilities. This inclusive approach allows teams of any size to enhance their collaborative efforts in diagram creation.
Description
Notula is a complimentary WYSIWYG Markdown editor designed for documentation as code, seamlessly integrating with your existing git repository. It presents the repository as a structured tree of documents, allowing users to edit without any visible syntax—no hashes, asterisks, or table pipes distracting them, even on the line where the cursor is located. Beyond basic editing, it introduces a review feature that traditional code editors lack, enabling users to comment on text passages, reply to comments, mention collaborators, suggest modifications, and mark discussions as resolved, with each mention generating a notification that appears in an inbox.
In this system, threads are maintained alongside the documents as plain files, ensuring that nothing is directly altered within the Markdown itself, which preserves the integrity of minor edits, such as a single-word change, as simple diffs. Tables can be manipulated directly as tables, while Mermaid diagrams are rendered as visual representations. The application utilizes the existing git on the user's machine, maintaining a non-intrusive approach by never rewriting history, staging the entire worktree, or changing branches.
It is entirely free, requires no user account, and operates independently of any server, supporting both macOS and Windows, though a version for Linux is still in development. While the source code remains proprietary and the builds are not yet code-signed, users should be prepared for an additional step during the initial launch to ensure a smooth experience.
