Drawcall enables AI agents to develop high-quality 3D applications more efficiently. To this end, we provide open-source libraries and assets based on our years of experience with AI and 3D. This leads to better results faster, while users retain creative control.
The idea combines my AI research at TU Darmstadt with my work on open-source tools for 3D and XR. The challenge was to give AI agents the tools they need to build and test functional 3D applications, while allowing users to determine the design.
Users describe to their preferred AI agent what they want to build. Drawcall provides the agent with tools to find or create suitable assets in the Market, build scenes, and review the results. Users can evaluate the result and improve it step by step with targeted feedback.
All assets in the Drawcall Market are free to use for commercial purposes. Users may therefore also use them in their own commercial projects. Any additional content submitted is subject to its respective rights.
We are already using our tools internally for robotics simulations, VR training applications, and other applications.
Our top goal for 2026 is to increase the number of monthly active users tenfold. In five years, we want to be the go-to solution that every AI agent automatically turns to when building something in 3D.
I’m building Drawcall as a solo founder. My central product question is how much the agent handles automatically and where users need direct control. The interface should be simple while still offering enough creative freedom for ambitious projects.
We cater to 3D design studios, small game studios, and web game developers, as well as companies that develop VR training programs or simulations. Our goal is to enable them to test more ideas with small teams and develop high-quality 3D applications more efficiently.

AI Startup Rising challenges my perspectives and supports me with guidance on my personal development, especially in areas outside my core competencies.
