Comparison
SpeakCAD vs Tinkercad: dragging shapes or describing parts
Tinkercad made CAD approachable by turning it into building blocks. It is great for learning and for simple shapes, but precision work means typing coordinates into many small boxes. SpeakCAD takes the accessibility further: the numbers go in a sentence, and the AI handles alignment, booleans and fillets.| Criterion | SpeakCAD | Tinkercad |
|---|---|---|
| Install | None: runs entirely in the browser | None: browser-based |
| Input | Text description, images, STL | Drag-and-drop primitives |
| Precision | Exact millimetres from your text | Manual position/size fields per shape |
| Fillets and chamfers | Yes, on request | Limited |
| Editing | Chat: “make walls 2 mm thicker” | Select and resize shapes |
| Parametric | Yes | No |
| Exports | STL, 3MF | STL, OBJ, GLTF, SVG |
| Account | E-mail signup, 5 free credits | Free Autodesk account |
| Best for | Functional parts with exact dimensions | Learning CAD, quick simple shapes |
Precision without the fiddling
A bracket with two M4 holes 40 mm apart is a two-minute description in SpeakCAD and a ten-minute alignment exercise in Tinkercad. Because SpeakCAD models are parametric, moving a hole later is a sentence rather than a re-drag.
Where Tinkercad shines
Tinkercad is free, excellent for children and classrooms, and its direct manipulation is intuitive for artistic or freeform arrangements of shapes. It also exports to more formats and integrates with Autodesk's ecosystem.
Where SpeakCAD shines
Anything with measurements: replacement parts, enclosures, brackets, organizers. The AI applies printability rules automatically and produces manifold meshes, so you spend less time repairing exports.
