COMPARISON
Automatic3D vs Sloyd
Sloyd and Automatic3D both help you create 3D models without modelling software, but they work on different principles. Sloyd uses parameterized procedural templates. Automatic3D uses generative AI from a text prompt.
LAST REVIEWED 2026-04
The short version
Sloyd isn't really a text-to-3D tool in the generative-AI sense. It works from a library of procedural templates — chairs, swords, buildings, props — that you customize with sliders. The output is consistently clean low-poly geometry because the underlying algorithm is deterministic. That's great when you want predictable, game-ready results. Automatic3D goes the other way: a prompt in plain English, an AI pipeline, an STL out. More flexible about what you can describe, less predictable about what you get back, targeted at 3D printing rather than game development.
CHOOSE SLOYD IF
- →You're making game assets and need predictable, low-poly topology.
- →You want parametric control — sliders for dimensions, shape variants.
- →Your object is in their template library (furniture, weapons, props, buildings).
- →You need clean UVs or real-time rendering budgets.
CHOOSE AUTOMATIC3D IF
- →You're making something to 3D print, not something to put in a game.
- →Your object isn't in any template library — it's something specific you imagined.
- →You prefer text prompts to sliders.
- →You want geometry density suitable for printing, not game budgets.
What each tool is
SLOYD
Sloyd (sloyd.ai) is a procedural 3D generator focused on game-ready low-poly assets. Instead of generating from a prompt, you pick a template (chair, weapon, character, building) and adjust parameters. Because the pipeline is procedural rather than neural, output topology is predictable and clean — typically triangle-counts and UV layouts suitable for real-time rendering. Sloyd offers a subscription model and integrates with common game engines.
AUTOMATIC3D
Automatic3D is a neural text-to-3D pipeline. You describe an object, the system generates a three-view concept image, and a mesh generator converts that into a 500K-triangle STL. Output is one-shot — you cannot dial a parameter and iterate in real time — but you can generate arbitrary objects that do not exist in any template library. The flow is tuned for 3D printing, not game rendering.

FAQ
Is Sloyd an AI tool?
Sloyd uses parameterized procedural generation, which is a different technique from neural text-to-3D. It produces consistent, predictable output because the algorithm is deterministic. Whether you call that "AI" is largely semantic — it's not a neural model learning from data the way Automatic3D's pipeline is.
Can Sloyd output STL for 3D printing?
Sloyd focuses on real-time game assets, so its output is optimized for low polygon counts and clean UVs. You can often export formats that convert to STL, but the geometry density may be too low for a detailed print. Automatic3D's output is tuned specifically for printing.
Can I get consistent results from Automatic3D like I can from Sloyd?
Not in the same way. Sloyd's procedural approach is deterministic: same parameters, same output. Automatic3D's pipeline includes neural generation, so even the same prompt can produce variations. This is a real trade-off — if predictability matters more than flexibility, a procedural tool will serve you better.
When would I use both tools?
It's a reasonable combination. Sloyd for the game assets in your project, Automatic3D for physical props or one-off printed pieces. They don't overlap much because they solve different problems.
