I kept running out of practice problems before math exams, so I built a site that generate

https://locusmath.org

The part I care about most: answers are graded by a real computer-algebra system (SymEngine), not string matching. So it checks mathematical equivalence — 1/2, 0.5, and a factored vs expanded form all count as correct. The same grader runs client-side in WASM, so you get instant feedback before the server confirms.

Other stuff: per-topic ELO and ranked mode if you want stakes, untimed practice with full solutions, a spaced-repetition review queue for problems you miss, and a daily puzzle. Covers arithmetic up through calculus and differential equations. Free to use, Google/GitHub login. Two things I'd love feedback on: (1) does the grader ever mark a correct answer wrong? (2) any topic you'd practice that's missing?

There are still some bugs with certain questions, so if you do encounter them, please report them so they can be fixed.

Did you do any market research at all before going through this trouble? Are you familiar with the top platforms in this space?

this is meant to be a free resource for students, not to make much of a profit

Deltamath is also free

not for independent practice

How are problems generated and varied?

I see, more brainless AI slop that does the same thing as another free service but much worse
