Frequently Asked Questions
How does diagram recognition work?
Our system analyzes diagrams in multiple steps: It first identifies the diagram type and structure, then analyzes the relationships between elements, and finally generates Mermaid code that preserves the visual layout and connections.
What types of diagrams are supported?
Currently, the tool is optimized for Flowcharts, Sequence Diagrams, UML Class Diagrams, and State Diagrams. While it may work on other types like Entity Relationship (ER) diagrams, accuracy is highest on standard flowcharts and process maps. It specifically handles actors, lifelines, and activation bars in sequence diagrams.
Can I edit the diagram after conversion?
Yes, easily. Since the output is text code, you can modify labels, add steps, or change logic instantly. You can also paste the code into the Mermaid Live Editor for visual editing.
Can I use the output in Notion or GitHub?
Absolutely. Mermaid is natively supported by GitHub, Notion, Obsidian, and GitLab. Simply wrap the generated code in a code block marked as mermaid, and these platforms will automatically render it as a diagram.
Why convert images to code instead of other formats?
Code is lighter and version-controllable. By converting diagrams to Mermaid, you can treat your documentation like code—track changes with Git and update text without redrawing the image.
What are common uses of diagram recognition?
Common use cases include:
- System design: Convert architecture diagrams to Mermaid
- Documentation: Transform diagrams from PDFs to code
- Team collaboration: Share and edit project diagrams
