Diagram Generator

The Diagram Generator is an AI-powered tool that allows users to instantly build brand-compliant Mermaid.js sequence diagrams. By analyzing natural language descriptions or visual reference images, the tool generates raw Mermaid code, renders a live preview, and offers automatic syntax repair.

Key Capabilities

  • Generates valid Mermaid.js sequence diagrams based on text descriptions.
  • Analyzes uploaded reference images (.jpg, .jpeg, .png, .webp) to map out corresponding architectural sequences.
  • Enforces company-specific terminology by applying custom Neural Style Overrides during generation.
  • Sanitizes generated code automatically by fixing literal newlines, converting self-loops to standard notes, and neutralizing angle brackets.
  • Detects Mermaid syntax errors during rendering and automatically sends the broken code and error message back to the AI for immediate repair.

Use the Global Diagrammer​

  1. Navigate to the Diagram Generator from the Workspace dashboard under Global Tools.
  2. Describe your architecture or workflow in the text area provided.
  3. Optionally, upload a reference image to guide the AI generation.
  4. Click Generate Code to instruct the AI to build the sequence.
  5. Click Render to view the live preview of your diagram.

Export and Download Options​

Once a diagram is successfully generated and rendered, users can export it in multiple formats:

  • Copy Code: Copies the raw, sanitized Mermaid syntax directly to your clipboard.
  • Download .mmd: Saves the raw Mermaid code as a .mmd file.
  • Download SVG: Downloads the rendered diagram as a scalable .svg image file.

Feature Draft Integration​

The same generation logic is also built into Author a Feature, reused rather than duplicated:

  • Automatic: The Information Architect decides on its own whether the feature is significant enough to warrant a diagram, and generates one if so - no action needed from you.
  • Manual override: Check Generate Architecture Diagram when creating the draft to force one regardless of the Information Architect's own judgment.
  • Update, not just create: If the target file already contains a diagram, SudoDocs updates it in place - preserving what's still accurate and incorporating the new feature - instead of always starting from scratch. You can also upload a reference image of an existing diagram; the AI redraws its logic as Mermaid, incorporating the new feature.

Docflows Integration​

Docflows uses this same generation logic too, fully automatically - there's no checkbox, since Docflows has no manual initiation step at all. If the Information Architect judges a suggestion significant enough, it generates or updates a diagram for the most relevant file as part of the same automated review that produces the rest of the suggestion.

AI Credit Costs​

  • Using the standalone Diagram Generator (this page): 1 AI Credit for a text-only description, 2 AI Credits with an attached reference image.
  • A diagram generated as part of an Author a Feature draft is included in that draft's overall credit cost - not charged separately.
  • A diagram generated as part of a Docflows suggestion adds a small additional charge on top of that suggestion's base cost, only when one is actually generated.
