Is it free?
Yes. Eigenform has a free tier with launch limits. See pricing and limits.
Early Access
Describe the problem.
Get a result you can trust.
Ask in plain English. Eigenform runs a real, validated simulation — reproducible, and yours to inspect.
No CAD license. No specialist. Nothing to install.
Not a Copilot
The whole job happens in the conversation.
Describe, run, inspect, and iterate in one place — whether you're chasing a curiosity or prototyping a real part. If you've used ChatGPT or Claude, you already know how to use it; there's nothing new to learn. The difference is what you can do.
Describe the problem…
One simple input. No complex simulation interface to learn.
Trustworthy and Reproducible
Physics, not LLM guesswork.
You can change the words. The physics doesn’t change. However you phrase the same problem, Eigenform returns the same numerical solution. If it can’t solve it, it tells you. No invented numbers.
Explore More. Reason With It.
Every question becomes an experiment.
Add a hole and solve again. Change the material. Vary the thickness. Try different boundary conditions. Ask what changed—and why. Each what-if becomes a validated simulation—not another workflow to manage.

What You Can Ask
Heat. Stress. Vibration. Fields across a shape.
"Create an interesting 2D deformation problem — you decide the dimensions, material, and loads."
"How does heat spread through a 100 mm aluminum plate during the first 30 seconds if one edge is suddenly held at 100 °C?"
"What are the first five vibration modes of this bracket?"
"Fix the plate's two bolt holes and press the top edge down 2 mm."
"Stretch a rubber block by 30% using a neo-Hookean model with E = 1 MPa."
"Solve a Poisson problem on the unit square. Use a 48×48 triangular mesh, zero value on the boundary, and source term 10*sin(pi*x)*sin(pi*y)."
Don't have a CAD file? Describe the part in words — Eigenform builds clean geometry to run on.
Inspect It, Don't Just Look at It
Every result expands into a full inspector.
Results arrive as live 3D views right in the chat. Expand one and the inspector opens — colormaps, mesh, contours, probes, cameras. That's the deal throughout: describe the problem in words, then inspect the result with your hands.

Consulting
Need physics Eigenform doesn't have yet?
We build custom workflows and physics into Eigenform under contract — your simulation process, your material models, your outputs, in the same conversational interface. Engagements are scoped and priced per project. Tell us what you need:
Common Questions
The practical things to know.
Does it replace simulation experts?
No. Eigenform is meant to make early modeling faster and assumptions more visible. It helps you explore supported workflows, not skip expert judgment when the stakes are high.
What physics does it support today?
The first supported paths focus on finite-element workflows like heat transfer, field simulations, and early structural or modal behavior. If a request is outside the supported path, Eigenform should say so.
What happens after I sign up?
You can start using the free tier right away, subject to daily limits. Paid plans are coming soon, and as Eigenform grows, we may increase limits across all tiers.
Who benefits the most at this stage?
At this stage, Eigenform is most useful for research and prototyping—especially for academic researchers, R&D engineers exploring early designs, and small engineering teams running analysis.
Bring a question you'd
normally just guess at.
The free tier is open — real solves, real results, today. Join early and help decide what Eigenform learns next: the physics it supports and the features it builds.
