Who It's For
Built for engineers at every level
Whether you're a student learning mechanical design or a company trying to cut design hours - MecAI is built for you.
Mechanical Engineers
Skip the repetitive CAD work for standard components. Generate, iterate, and move on to the design problems that actually need your expertise.
Startups & Small Teams
Early-stage hardware startups can't always afford full engineering teams. MecAI helps small teams punch above their weight on mechanical design.
Engineering Companies
Reduce the hours your engineers spend on standard component design. Let MecAI handle the routine parts so your team focuses on innovation.
Our Vision
Why we're
building this
Mechanical design hasn't changed much in decades. Engineers still spend hours manually creating standard components that could be generated in seconds. We think that's a problem worth solving.
MecAI starts with individual components - gears, bolts, shafts - and over time will handle full assemblies, simulations, and more. We're starting focused and expanding deliberately.
Every component is generated parametrically - exact, standards-driven geometry computed from your dimensions. Not AI-approximated meshes.
MecAI is purpose-built to generate engineering components - grounded in real mathematics, physics, and material science. Not just shapes - real engineering.
How It Works
Prompt to part.
“Flanged coupling hub, 40mm bore, stainless steel”
-
Describe
Just describe the part in plain language - no CAD experience needed. MecAI understands standard callouts, materials, and dimensions.
-
Generate
Parametric, standards-driven geometry is computed from your description - exact dimensions, not an AI-approximated mesh.
-
Export
Drop the file straight into any CAD package, 3D printer, or laser cutter. STEP, STL, and DXF all supported.

What MecAI Does
Six capabilities.
Component Generation
Generate standard mechanical components like gears, bolts, brackets, and shafts instantly - just describe what you need.
Engineering Mathematics
MecAI solves real engineering equations - gear ratios, load calculations, tolerances, thread specifications - so every component is mathematically sound.
Physics-Based Design
Components are designed with physical constraints in mind - stress, force distribution, fatigue limits, and mechanical behaviour under real-world conditions.
Material Science
MecAI recommends the right material for every component - considering tensile strength, corrosion resistance, weight, and application environment.
Built for Students
Learn by doing. MecAI explains the engineering decisions behind every component it generates - building real understanding, not just output.
Save Time & Money
Skip hours of manual CAD work for standard parts. Generate, iterate, and move on - so engineers focus on what needs their expertise.
