Engineering AI platform for CAD and simulation

gNucleus is an engineering AI platform focused on CAD generation, simulation workflows, data labeling, model training, and AI serving for industrial teams. The product page describes it as an end-to-end platform that combines engineering data services, a generative engineering model family, and AI agents for design, simulation, and optimization.

The site also positions gNucleus for enterprise deployment, with managed or private cloud options and custom model training on proprietary engineering data. A separate pricing page shows both individual plans with monthly credits and an enterprise offering that covers data services, training, serving, and support.

Core capabilities

Design Spec Agent

Generate specifications with key parameters, engineering constraints, and validation support before moving into design work.

CAD generation

Create feature-based CAD parts and assemblies from text, images, or DXF, with exports that include native formats such as Solidworks and Catia plus universal formats like STEP and STL.

Image-to-CAD conversion

Turn PDFs, DXFs, PNGs, and JPGs into editable 2D sketches and 3D solid models for digitizing legacy drawings and other source files.

Simulation automation

Run multi-physics simulation workflows and connect with major CAE tools including Ansys and Altair.

Optimization support

Interpret simulation results and suggest design changes using an optimization agent that summarizes expert-level insights from the workflow.

Enterprise deployment and services

Offer managed or private cloud deployment, with enterprise APIs and training/serving services for proprietary engineering data.

Common use cases

Create CAD from source material
Use the CAD agent to create feature-based parts or assemblies from text, images, or DXF when starting a design from a rough concept or legacy file.
Run engineering simulation workflows
Use the simulation agent to execute multi-physics workflows and connect the output to tools such as Ansys or Altair when validating a design before manufacturing.
Refine designs after analysis
Use the optimization agent to review simulation outcomes and suggest design changes when a team needs iterative improvement rather than a one-off model output.
Build custom industrial AI workflows
Use the enterprise training and serving stack to train proprietary models on in-house engineering data when an organization needs custom behavior and controlled deployment.
Label and evaluate engineering datasets
Use the platform’s data labeling and evaluation services for CAD and simulation datasets when preparing engineering data for model training or validation.

Pros and Cons

Pros

Covers multiple stages of the engineering workflow, from specification and CAD creation to simulation and optimization.
Supports several input types, including text, images, PDFs, DXFs, and common CAD exports.
Includes both self-serve plans and enterprise services, which gives it room to fit individual engineers and larger teams.
Provides support for common CAD ecosystems and exports to native and neutral formats.
Offers deployment flexibility through managed or private cloud options.

Cons

The pricing page says payment options are still being set up for non-free plans, so subscription management may not yet be fully self-serve.
Public documentation on integrations, APIs, and supported workflows is limited on the marketing pages provided.

FAQ

What CAD systems does gNucleus support?

gNucleus AI supports B-rep-based CAD systems, including Solidworks, Catia, Creo, NX, and more. Its web tools currently support Solidworks, Catia, FreeCAD, and Tiangong CAD in the China region.

How do credits work?

The pricing page says monthly credits cover generation and downloads. Successful CAD generation via chat costs 5 credits, part downloads cost 10 to 20 credits depending on whether parameters are included, and assembly downloads cost 50 to 100 credits depending on whether parameters are included.

Does gNucleus offer a free plan or enterprise plan?

Yes. The pricing page includes Basic, Professional, and Premium individual plans, and a separate enterprise offering for teams that need industrial AI data services, training, and serving.

Can I upgrade or cancel my plan myself?

For non-free plans, the pricing page says users should contact `contact@gnucleus.ai` to upgrade or cancel. It also notes that payment options are still being set up.

How do I get support?

Enterprise customers get a dedicated 24x5 customer support team. For other users, the contact page and pricing page both direct support requests to `contact@gnucleus.ai`.
