Questions

What does the free plan show?

Every property value with source citations is public. Sign in and interactive curves, the Material Selector, and regulatory screening across 22 regulations also unlock. Pro adds natural-language search, side-by-side comparison, and CAE exports.

What CAE formats are supported?

Abaqus (.inp), LS-DYNA (.k), ANSYS APDL (.mac), Ansys Workbench Engineering Data (.xml — MatML, imports across Mechanical, Fluent, CFX & LS-DYNA), Nastran (.bdf) — including Simcenter Nastran NX and OptiStruct dialects — Radioss (.rad), SolidWorks (.sldmat), CSV, and JSON: 11 formats total. All include automatic unit conversion to format-native unit profiles like Abaqus mm-N-s, LS-DYNA g-mm-ms, and ANSYS SI.

Where does the data come from?

57 open sources: peer-reviewed papers with DOI links, 9 public-domain government handbooks including MIL-HDBK-5J (metals) and MIL-HDBK-17 (composites), and 20 open databases (JARVIS-DFT, matminer, OpenPoly). Every value carries its source citation and a confidence score; every MIL-HDBK curve carries its figure number.

What about regulatory screening?

Pro unlocks pass/fail outcomes for all 22 regulations — RoHS, REACH SVHC, Prop 65, TSCA, Conflict Minerals, ITAR, EAR, and more — plus the underlying substance lists, threshold values, CAS numbers, and source citations. RoHS, REACH SVHC, and Prop 65 are validated against the official ECHA and OEHHA substance lists.

Can I try before I buy?

Yes. The free tier shows every property value with source citations, and any signed-in user gets interactive curves, the Material Selector, and regulatory screening across 22 regulations. Upgrade to Pro anytime for natural-language search, comparison, and CAE exports.

What's the Team plan?

A flat-fee bundle for 3, 4, or 5 engineers under shared billing — same Pro features, one owner manages the seat list. We're still building it; email matworldai@gmail.com if you want to be notified when it launches.

Can I cancel anytime?

Yes. Open Settings → Billing & usage → Manage subscription to cancel via the Stripe customer portal. You keep Pro access until the end of your current billing period.

Do you offer enterprise plans?

Yes. Contact us at matworldai@gmail.com for SSO/SAML, bulk data access, custom integrations, and on-premise deployment.
