Tomorrow's innovations won't start with a drawing. They will start with a prompt.
Bldrs.ai is the world's fastest browser-based CAD viewer and collaboration platform, powered by AI. We're building the future where Digital Twins and artificial intelligence transform how imagination becomes reality.
Think AI + GitHub for CAD. We enable teams to collaborate on Digital Twin engineering data with unprecedented speed, open standards, and intelligent assistance.
Modern Collaboration Platform
Current CAD tooling is stuck in the dark ages. Google Docs, GitHub, and Figma have shown what users want. We're bringing that same level of collaboration to Digital Twins.
AI-Powered Interface
AI Coding and Assistants replace thousands of buttons with a flexible, task-oriented natural language interface. Build anything with a prompt.
Built for the Future
Frontier models will soon use sophisticated computational engineering tools and physics models to create truly advanced technologies.
