Describe the Interaction
Write a short description of the flow between actors or systems. For example: 'User sends a login request to the auth service, which validates credentials and returns a token.'

Describe Interactions, Get a Sequence Diagram
Turn a plain-text description of system interactions into a clean sequence diagram. No diagramming tool needed, no syntax to learn. Just describe who talks to whom and Mapen draws the lifelines and messages.
From Description to Diagram in Three Steps
Skip the manual drawing. Mapen reads your interaction description and produces a sequence diagram you can export or edit.
Generate the Diagram
Paste your text into Mapen and select the sequence diagram option. The AI creates a UML sequence diagram with lifelines, activation bars, and messages.
Export or Edit
Download the diagram as an image, PDF, or Mermaid code. Or open it in the editor to adjust lifelines, add notes, and refine the flow.
Where Text-to-Sequence Fits
Engineers, architects, and technical writers use Mapen to turn interaction descriptions into clear diagrams without manual drafting.
API Design Reviews
Describe a new endpoint flow and generate a sequence diagram to share during design review. Catch missing steps before code is written.
Try for API DesignSystem Architecture Docs
Document how services communicate by writing out the interaction flow. Mapen produces a diagram that fits directly into your architecture docs.
Try for ArchitectureOnboarding Guides
Create sequence diagrams for new team members to understand request flows. Update the text and regenerate when the system changes.

Describe the exact sequence of calls that leads to a bug. Generate a diagram to share with the team so everyone sees the same flow.
Try for DebuggingWhy Mapen for Sequence Diagrams
Most sequence diagram tools force you to learn a syntax or draw every lifeline by hand. Mapen starts from your description and gives you a diagram you can use immediately.
No Syntax to Learn
Write plain English or technical prose. Mapen handles the translation to UML sequence diagram notation.
Editable Output
The generated diagram is fully editable. Add notes, rearrange lifelines, or change the flow in the Mapen editor.
Multiple Export Formats
Export as image, PDF, or Mermaid code. Use the diagram in docs, slides, or code repositories.
Faster First Drafts
Describe the interaction once and get a complete diagram. No need to draw lifelines and messages from scratch.
Works with Other Diagrams
Mapen also generates flowcharts and architecture diagrams from text. Switch between diagram types without switching tools.
