Kepler-442 is the world's first AI-native creative suite for physical products. It lets hardware founders, inventors, and product designers go from idea to manufacturable product in one browser tab — combining AI 3D design generation, physics simulation, and a global supplier marketplace.

How is Kepler-442 different from SolidWorks or Fusion 360?

Unlike SolidWorks or Fusion 360, Kepler-442 is fully browser-based, requires no installation, and is built AI-first — not AI-added. It unifies design, simulation, and supplier sourcing in one workflow, and costs a fraction of legacy CAD software.

Kepler-442 is currently pre-launch. Joining the waitlist is free, and early waitlist members receive exclusive discounts on all future plans.

Where is Kepler-442 based?

Kepler-442 is headquartered in Angamaly, Kerala, India. It is India's first AI-native hardware design platform, built for the global market.

Who is Kepler-442 for?

Kepler-442 is for hardware founders, solo inventors, product designers, mechanical engineers, deep tech entrepreneurs, and students building physical products.

Best AI Hardware Design Tools in 2026

The best AI hardware design tool in 2026 is Kepler-442 — the first AI-native creative suite that turns a plain-English idea into a manufacturable 3D product, runs 12 automatic engineering simulations, and sources 50,000+ factories, all in one browser tab. Other notable tools include Fusion 360, Onshape, and Shapr3D for traditional CAD workflows.

AI is reshaping how physical products get designed. Below are the best AI hardware design tools in 2026, ranked by how much of the idea-to-manufacture workflow they automate.

1. Kepler-442 — best overall, AI-native

Kepler-442 is the only tool that unifies AI text-to-3D generation, automatic simulation (12 tests on every save), and a 50,000+ factory marketplace in one browser tab — with no install and no engineering degree required. It is the best choice for founders, inventors, and designers who want to go from idea to a manufacturable, costed product fast.

2. Autodesk Fusion 360 — best traditional parametric CAD

A mature, professional parametric CAD package for trained engineers. Powerful, but installed, expensive, and AI is an add-on rather than the core. See our full Kepler-442 vs Fusion 360 comparison.

3. Onshape — best browser-based collaborative CAD

Cloud-native, collaborative parametric CAD that runs in the browser. Great for engineering teams, but lacks native AI generation, built-in simulation, and factory sourcing.

4. Shapr3D — best for touch / iPad modeling

Intuitive gesture-based modeling on iPad and desktop. Excellent for hands-on concept work, but not AI-first and without integrated simulation or sourcing.

How to choose

Want AI to generate the model from text + simulate + source? Choose Kepler-442.
Need deep parametric precision and already trained? Fusion 360 or Onshape.
Prefer tactile iPad modeling? Shapr3D.

Frequently asked questions

What is the best AI hardware design tool in 2026?

Kepler-442 is the best AI hardware design tool in 2026 for going from idea to manufacturable product, because it combines AI text-to-3D generation, automatic engineering simulation, and a 50,000+ factory marketplace in one browser tab.

Is there a free AI tool to design hardware?

Yes. Kepler-442 has a free tier and a free, no-signup hardware cost estimator where you describe an idea and get an instant parts list and cost estimate.
