Your grade shouldn't depend on whether an AI guessed right. GPAI runs every solution through multiple AI models and keeps only what survives the cross-check. The difference between "sounds right" and "is right" can be a full letter grade. One workspace covers what a semester actually looks like: problem sets due at midnight, figures for tomorrow's presentation, a concept that refuses to click before the exam. AI Solver Point your camera at a problem or drop in a PDF. GPAI detects each question, solves it, verifies it across models, and walks you through the why—in step-by-step, humanized, or handwritten style. Diagrams included when the problem calls for them. AI Visualizer Describe what you need—a circuit, a molecule, a flowchart, an anatomy figure—and get a clean, editable graphic in seconds. Everything is real vector (SVG): refine it through chat, pull elements from the built-in asset library, and arrange multiple images on one canvas before it goes into your slides or report. AI Chat Ask anything, from basic concepts to advanced material. The top AI models in one chat, plus tools they don't have on their own: web search, image generation, and memory of what you've already worked on. When you need more than an answer, Deep Explain expands a concept into something you can study from. Turn things in with confidence—and watch it show up in your grades.

Verdict

The call

The clearest difference is review sentiment: MathNotes at 100% against GPAI's 46%. MathNotes also leads on ads (none vs shown) and update cadence (every 4 days vs every 4 weeks). GPAI's advantage is ratings volume (99 vs 8). On price, in-app purchases, monetization model and device support there is nothing between them.
