DiagramMatic

DiagramMatic is a ChatGPT-based assistant that converts plain-text descriptions of processes and flows into clear Mermaid diagrams. Describe how a system works, a business process, a user journey, or an algorithm, and it analyzes the text and outputs valid Mermaid code.

How it works

Instead of simply “drawing from text,” DiagramMatic structures your input first and identifies key logic elements:

• Steps and sequence
• Branches and conditions
• Loops
• Relationships between components

If details are missing, it asks clarifying questions so the final diagram matches the intended flow and avoids logical gaps.

Language support and diagram translation

You can write descriptions in Russian, Spanish, English, and other languages. Diagram labels and comments follow the language of your input. If needed, DiagramMatic can translate an existing diagram to another language while keeping the structure and meaning intact.

Who it’s for

DiagramMatic is useful for:

• Analysts and developers documenting systems
• Product managers mapping workflows
• Teachers and students creating visual explanations
• Anyone who needs sequence diagrams, flowcharts, state diagrams, and similar Mermaid-based visuals from text
