Leo AI

What is Leo AI?

Leo AI is an engineering assistant built for mechanical design teams. Engineers ask technical questions and get answers grounded in their own PLM data plus more than a million engineering sources, with references to the sources used. Leo can find formulas and run calculations, search a company's existing parts and 120M+ vendor parts so designers reuse what exists, and generate conceptual images, 3D meshes and editable CAD assemblies from a plain-language description. It runs inside the CAD editor through an installed add-in or in the browser, and connects to systems such as SOLIDWORKS, Onshape, Autodesk Inventor and Teamcenter. The vendor states that it is SOC 2 certified and GDPR compliant, with no training on customer data. You subscribe through the Leo sign-up page; prices are not published, so confirm package costs with the vendor.

Use cases

• Answer mechanical engineering questions with sources
• Search existing parts before designing new ones

Why use Leo AI

• Finding and reusing existing parts reduces repeated design work.
• Answers draw on your own PLM data and cite trusted engineering sources.
• Output is meant to be editable CAD, not only a mesh or an image.
• It works inside the CAD editor, so engineers do not switch tools to ask questions.
