Digen
Digen — an AI-powered diagram generator.
The idea came from a problem I faced in my Software Engineering subject. Creating diagrams such as Data Flow Diagrams, Class Diagrams, and Sequence Diagrams often meant spending a lot of time searching for examples or trying to generate reference images with AI tools.
Image-based outputs were often inconsistent and not suitable for actual project work—so I built something more practical.
Instead of generating images, Digen generates real diagrams from simple prompts using Mermaid.js.
For example, you can ask:
- Create a Class Diagram for a Library Management System
- Generate a Sequence Diagram for User Authentication
- Create a Data Flow Diagram for an E-commerce Website
- Create a Diagram for Food chain
- Make a mind map for AI
Digen generates the diagram instantly (about 2–3 seconds).
Tech stack
How Digen works
I designed Digen around a simple principle: diagrams should be built from system thinking—not from random drawing. You describe, Digen structures the result.
Describe your system
Write in plain English: actors, components, steps, and rules.
Get Mermaid code
Digen outputs copy-ready Mermaid with consistent formatting.
Iterate fast
Refine by prompting again—without starting from scratch.
Supported diagram styles
If you want something specific, describe relationships and steps—the prompt is the source of truth.
What you’ll get
Flowcharts & process maps
Turn workflows into clean Mermaid diagrams with readable structure.
UML class + system views
Generate UML class diagrams and architecture-style snapshots.
Sequences & states
Model interactions and state transitions for real-world systems.

Tip for best results
Include entities (“User”, “Order Service”), actions (“creates”, “verifies”), and order (“first”, “then”). Digen turns that structure into consistent Mermaid output.
