The architecture model your AI can read, write, and reason about

Revelation turns Excel or JSON into rich, interactive architecture diagrams — instantly, for free, with no account required.

Define your systems and interactions in a simple flat JSON model or a familiar Excel workbook. Revelation generates C4, ArchiMate, BPMN, sequence, flowchart, and entity relationship diagrams automatically — and because the model is plain JSON, your AI tools can generate and analyse it too.

Our Structured Approach - From Discovery to Delivery

1. Capture consistent architecture with Excel templates.

2. Automatically generate diagrams directly from your workbooks.

3. Extend the model to include roadmaps and solution options.

4. Use reference models to accelerate discovery and ensure consistency.

5. Add flowcharts describing business processes ...

6. ...and entity relationships to understand data structure and context

7. Leverage structured data formats for AI-driven insights

8. Version control changes with Git-compatible, text-based models

From data to diagram in seconds

Load a JSON model, import an Excel workbook, or open one of 40+ reference models — and Revelation automatically applies a layout and renders your diagram. Multiple layout algorithms are available to suit different diagram styles.

IF automated layouts don't meet your needs, switch to Dynamic layout and drag systems to refine the layout — interactions re-route automatically. Resize elements to suit the composition. Add new systems or interactions directly from the toolbar and edit their properties through a guided dialog that ensures your model stays consistent. Save your layout back to the model when you are happy with it.

The model, systems, interactions, and raw JSON are always visible as tabs alongside the diagram, so the data and the picture are never out of sync.
