Compare Notula vs. SysMLv2 Editor

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.

The SysMLv2 Editor is an extension for Visual Studio Code that allows users to create SysML v2 models using a textual format, developed by Change Vision, Inc. These models are saved as standard .sysml files, enabling them to be managed in Git repositories, compared in pull requests, and evaluated alongside other source code components. Among its features are syntax highlighting, real-time validation according to the SysML v2 grammar, the ability to navigate to definitions, an outline view, and the capability to generate diagrams for analyzing both structure and behavior. While diagrams are provided in a read-only format, allowing for text-based editing, Change Vision also offers an early access version of the SysMLv2 Modeler for direct diagram manipulation. The SysMLv2 Editor is compatible with Windows, macOS, and Linux operating systems. Users can access it through an Astah SysML, Astah System Safety, or Astah Faculty Site License without any additional purchases, and a 20-day free trial is also offered. However, it should be noted that the editor does not support the importation of SysML v1 models from Astah SysML, ensuring a clear distinction between different SysML versions. This focus on SysML v2 could enhance users' experience by providing improved functionalities and a more modern approach to modeling.
