The Future ofStructural DesignStarts From the Ground.
ConGro AI — the world's first AI tool that automates structural design software. Live on ETABS. Revit and more in pipeline. Days of modelling, compressed into minutes.

Live, Side-By-Side With Your Model
OAPI · ETABSConGro AI is a separate desktop app that connects to your open ETABS session through the CSI OAPI. No file imports. No manual copy-paste.
Type a request: "run the analysis and tell me the results."
ConGro AI sends the command to your already-open ETABS via the CSI OAPI — analysis runs, results stream back.
Hits a real engineering issue (mass source missing) — explains the fix in plain English.
Inside The App
UI · 3 CLOSE-UPSBuilt for engineers — pick your AI tier, choose your tools, configure designs to ASCE 7-22 / AISC 360-22 / ACI 318-19 spec.
Pick your tier per message
Basic (Haiku 4.5, 1 credit) for fast lookups. Advanced (Sonnet 4.6, 5) for design work. Max (Opus 4.7, 8) for the hardest problems. Switch mid-conversation.
Toggle the right tools
ETABS Engine for direct model control. Rule Engine for code-checked research. Web Search, Code Compliance, Thinking, custom Instructions. Each is its own credit line.
Full ASCE 7-22 / AISC depth
Configure optimization with risk category, R / Cd / Ω₀ / Iₑ, drift limits, target D/C ratio, iteration count, convergence. Real engineering parameters, not generic AI knobs.
What ConGro AI Does
F-CARDS · 5AI-driven automation for the entire structural design workflow.
AI-Powered Design
Machine learning algorithms that understand structural engineering principles and automate design decisions.
Design Automation
Tasks that take hours or days manually are significantly accelerated. Model generation, load assignment, and structural setup — automated.
Multi-Software Support
One AI engine that speaks the language of every major structural design platform. Live on ETABS today; Revit next, with the rest of the industry rolling out after.
Code-Compliant Output
Generated designs follow building codes and standards. Every output is meant to be reviewed and verified by the engineer — ConGro AI assists, not replaces.
Iterative Optimization
AI iterates through design options to find optimal member sizes, reinforcement, and configurations.

How It Works
PROCEDURE · 6 STEPSFrom a building description to a fully automated structural model in six steps.
Describe Your Building
01 / 06Tell ConGro AI what you want to build — building type, dimensions, number of stories, materials, location. The AI asks smart follow-up questions to fill in the gaps, just like a senior engineer would during a kickoff meeting.
Automated Code Research
02 / 06ConGro AI searches through structural engineering codes, standards, and design guides to pull the relevant provisions for your specific building — seismic category, wind exposure, material specs, load combinations, member sizing guidelines.
Design Report Generation
03 / 06A comprehensive structural design report is generated with every numerical value needed to build your model — grid coordinates, story heights, material properties, section sizes, load values, and design combinations. This becomes the single source of truth.
Automated Model Creation
04 / 06ConGro AI writes and executes scripts directly in your structural analysis software (ETABS), building the model phase by phase — geometry, properties, loads, analysis, and design checks. Each phase is verified before moving to the next.
Self-Correcting Pipeline
05 / 06If a script encounters an error, the AI reads the log, diagnoses the issue, rewrites the fix, and re-executes — automatically, without your intervention. The same way an engineer would debug their own work.
Real-Time Progress
06 / 06Watch the entire process unfold live — research findings, design decisions, script execution results, and design check outcomes all stream into your screen as they happen. Every artifact is saved and accessible.
