Math answers that are actually correct.

No AI guessing. Every answer is computed by a symbolic engine and verified by substitution. If it says verified, it's right.

How it works

MathProof doesn't use a large language model. It parses your question, routes it to a symbolic math engine, computes the exact answer, then verifies it.

1

You ask in plain English

Type any math question — algebra, calculus, number theory, combinatorics. No special formatting needed.

2

The engine computes

Your question is parsed and routed to a SymPy-based solver. It finds the exact answer — no approximations, no guessing.

3

The answer is verified

Every answer is checked by substitution. If x = 3 is a solution, the engine plugs it back in and confirms. That's why we can guarantee it.

Our guarantee

We're so confident in our math engine that we put something on the line.

Wrong verified answer? 20 free solves on us.

If MathProof gives you a verified math answer that's wrong, submit a challenge. If you're right, you get 20 solve credits — no questions asked.

We can make this guarantee because we don't guess. The engine computes answers symbolically and verifies every one by substitution. There's no statistical model that might be wrong 3% of the time.

Beyond math.

The same approach — deterministic engines instead of statistical guessing — extends far beyond solving equations.

Causal reasoning

Ask "what if?" and get a real answer.

MathProof is built on Judea Pearl's causal inference framework. That means it doesn't just find correlations — it can reason about cause and effect, interventions, and counterfactuals. "What would have happened if X?" is a question LLMs can't answer. We can.

"If the braking distance were 10% shorter, would the collision have been avoided?" — a question with a deterministic answer, not a guess.

Way beyond math class

Physics, chemistry, statistics, economics, logic, engineering, CS, finance, nursing, and unit conversions — all verified.

Industries where wrong answers cost lives

Autonomous vehicles, medical diagnosis, aerospace, insurance — anywhere you need to know what actually caused something, not what correlated with it.
