Curve Fit BenchMade by physicists who fit data every day.
Curve Fit Bench began as a question in a lab: why does every fit start with a guess? It grew into a tool that lets the data choose — and, when no known model is right, builds one.

If it helped, cite it.
Citations are what let two early-career researchers justify the hours that go into new models and verification. A line in your methods section makes a real difference.
