Your AI Regulatory & Chemical Safety Expert
Rex knows your Safety Data Sheets inside and out. Ask it anything about the chemicals your company works with, in plain language, and get an expert answer in seconds — grounded in your own SDS library.
The Work That Used to Take Hours, Done in Seconds.
Rex does the work that used to take your team hours. It writes Safe Work Procedures and other compliance documents for any product, ready to review and use. It finds safer alternatives — matching on how a product is used, not just its name — so you can reduce hazards in your workplace with confidence. It analyzes your entire library at once: show me everything flammable in a Building, tell me which products are corrosive, flag what shouldn't be stored together. And when you need it on paper, Rex exports the whole thing to Excel, Word, or PDF — audit-ready.
Everyday Questions, Answered Instantly.
It's just as sharp on the everyday questions.
- What do I do in a spill?

- How should this be stored and handled?
