Structural analysis for every engineer worldwide
Paste JSON or upload an IFC file for instant 3D structural analysis — detect soft storey, floating columns, collapse risk, wind loads, and glass stress. Chat with the AI Copilot. Export IS 456 / ASCE 7 reports in one click.
How it works
Three steps to safety
Paste JSON
Describe your building in JSON — columns, beams, storey heights, loads. Use our example as a starting point.
AI Instant Score
The engine returns your structural safety score and core check results in under 2 seconds. No sign-up needed.
