Leo AI

Leo AI is a design copilot built for mechanical engineers, built by researchers and engineers with backgrounds at Microsoft, MIT, and the Technion. At its core is what the company calls a Large Mechanical Model, an AI system trained on more than a million engineering sources and CAD files that can turn text descriptions, sketches, specs, and CAD constraints into 3D CAD models, including full assemblies generated from a text prompt. Beyond model generation, Leo answers technical engineering questions with citations drawn from its training sources and from a user's own PLM data, performs calculations such as stress analysis and material selection, and searches a catalog of more than 120 million vendor parts to help engineers find suitable components. The company reports the tool is used by over 50,000 engineers and claims it can cut engineering time and cost by up to 70% and save individual engineers several hours per week, though these figures come from the vendor and are not independently verified. Leo is positioned for engineering teams at established firms rather than hobbyists, and the company states it is SOC 2 certified and GDPR compliant with no training on customer data. Integration with the Onshape CAD platform is described as planned rather than currently available, so how well Leo fits into an existing CAD toolchain today is unclear.
