MathGPT popularized the "photo your homework, get AI steps" flow and built a strong AP-exam hub on top. It's a polished product — but the most useful pieces (video explanations beyond the free quota, full AP mock exams, the mobile PocketMath app's advanced features) sit behind MathGPT Unlimited at 6.99/month annual. AI-Math is a web-first, free alternative built around the same workflow.
What MathGPT does well
The standout is AI-generated video explanations with animated diagrams — students who learn visually get a lot from it. The AP exam hub (Calculus AB/BC, Statistics, Precalculus, Physics 1) bundles units, mock exams, and printable study sheets in one place. And the camera-first mobile app (PocketMath) is fast at OCR.
Where MathGPT falls short
After the free daily question budget, the deeper steps and unlimited video explanations require Unlimited. The AP hub's full mock exams are similarly gated. For students who want unlimited free step-by-step solutions to learn the method — not just one answer per day — the paywall is in exactly the wrong place.
It's also product-led-by-mobile: the web experience is good, but the company pushes you toward the app for the best features.
What AI-Math does differently
AI-Math is free, web-first, with a generous daily quota for step-by-step solutions — and step-by-step explanations are never paywalled. You can paste an equation, type it, or upload a photo and get the AI to walk you through the reasoning in plain English ("we factor here because the discriminant is a perfect square") instead of just listing symbolic transitions.
Companion content — a glossary, cheat sheets, worked example library, and an in-depth blog — is fully free and indexed for browsing, not locked behind a chat session.
Side-by-side
We're transparent: MathGPT's video explanations and AP hub UX are still ahead of where AI-Math is on day one of those features. If your only goal is "watch animated AP Calculus walkthroughs," MathGPT Unlimited is a solid product. For everything else — instant solving, unlimited step explanations, web workflow, no install — AI-Math wins.
Verdict
Pick AI-Math if you study on a laptop, want unlimited free step-by-step explanations, and prefer browsing a free reference library. Pick MathGPT Unlimited if you specifically value AI-generated video walkthroughs and full AP mock exams enough to pay monthly.
Try AI-Math's free solver — no install, no signup, no paywall on the steps that actually teach you math.
