Why use our Chart/Diagram to Mermaid Converter?

Revitalize Old Diagrams

Have an old PNG architecture diagram but lost the source file? Don't redraw it from scratch. Upload the image, and our AI will reconstruct the logic into editable Mermaid code, bringing your legacy documentation back to life.

Understands Logic & Text

It's not just text recognition. Our AI analyzes shapes (diamonds, rectangles) and connections (arrows, lines) to understand the flow. It accurately translates Decision nodes and Process steps into the correct Mermaid graph syntax.

Whiteboard to Code

Turn your brainstorming sessions into documentation instantly. Snap a photo of your whiteboard flowcharts or napkin sketches, and let the AI digitize your rough ideas into clean, professional diagrams.

Edit & Version Control

Stop managing binary image files. By converting diagrams to Mermaid code, you can treat your documentation like code—track changes with Git, update text easily, and render it dynamically in Markdown or Notion.

Multi-Diagram Support

Whether it's a simple Flowchart, a complex Sequence Diagram, or a UML Class Diagram, our model is trained to recognize various diagram standards and convert them into the corresponding Mermaid graph types.

Secure Diagram Processing

We respect your intellectual property. Your diagrams and charts are processed securely and are permanently deleted from our servers shortly after conversion. No technical designs are stored or used for training.

Frequently Asked Questions

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.

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.

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.

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.

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.

Common use cases include:

  • System design: Convert architecture diagrams to Mermaid
