Leo AI

Leo AI is a web-based engineering design copilot for mechanical engineers and product designers that turns inputs like text, sketches, specifications, and CAD constraints into DFMA-optimized 3D CAD assemblies.

Key capabilities include:

• Text-to-CAD and sketch-to-CAD modeling that interprets mechanical language to generate detailed geometry and full assemblies.
• Engineering Q&A with citations, grounded in PLM data and 1M+ engineering sources, designed to avoid uncited “random internet” answers.
• Part retrieval and recommendations, helping teams select components from internal PLM libraries and 120M+ vendor parts.
• Engineering calculations support (for example stress analysis, unit conversions, and material selection), including formula identification, calculation execution, and source citations.

Pricing: Annual enterprise subscription priced per user ("Leo for teams"), quoted by team size and connected systems; no free trial, tailored demo available.

What makes it notable: it is domain-specific (built on a patented “Large Mechanical Model”), supports company-specific design guidelines and legacy knowledge, and emphasizes enterprise security (SOC 2 certified, GDPR compliant, with zero training on customer data).
