Catenda — The Open CDE for Efficient Project Communication

 

All the tools. For everyone involved. Smarter with AI.

 


 Open BIM — Open standards for maximum independence

The open ecosystem gives you full control over your data and the freedom to choose your tools—without data silos, closed formats, or vendor lock-in.

Open Standards

IFC and BCF establish open BIM standards for maximum flexibility. Open APIs and flexible interfaces enable the seamless integration of popular tools such as Revit, Archicad, Vectorworks, Tekla, Solibri, Navisworks, etc.—for smooth collaboration and maximum flexibility.

Your AI, Your Choice

No proprietary AI system. Using the open Model Context Protocol (MCP), you can connect the tools you already trust—Claude, ChatGPT, Gemini, or your own models—directly to your project data.

Security & Data Sovereignty

Full control over sensitive project data through a strict, role-based permissions system. The defined security policies apply without exception to all project participants as well as to every externally connected tool.


 Catenda AI — Intelligent AI agents for your project data

Using the open Model Context Protocol (MCP), Catenda AI seamlessly and securely connects your preferred AI tools to your data. Thanks to a precise authorization system, the AI only sees what the respective user is actually permitted to see. The perfect combination of data protection and flexibility.

ai 1 Stay Ahead Image

Identifying Problems Early

Identify potential problems before they affect deadlines and costs. AI-powered agents analyze BCF threads and project documents, provide transparency for decision-making, and help identify planning errors, missing information, and critical assumptions early on.

ai 2 Automate Manual Work Image

Automating Manual Work

Easily manage BCF tickets using voice commands. AI agents automate tasks, reminders, and workflows for more efficient collaboration.

ai 4 Progress Reports (Light, Scaled)

Progress Reports

Create customized progress reports with the click of a button. BCF threads are automatically converted into structured reports that include priorities and next steps.

ai 3 Talk To Your Models Image

Talk to AI

Query IFC data directly, perform quantity takeoffs, and identify missing properties and naming errors. Have AI agents automatically create BCF topics for any inconsistencies found and convert raw data into a structured task list.
