How We Analyzed
Our team spent over 150 hours between January and May 2024, benchmarking 10+ AI homework helpers using 30 real science questions per tool-10 each in physics, chemistry, and biology. We selected problems from AP and college intro coursework, looking for a mix of equations, definitions, and concept explanations.
We scored each platform in four areas:
Student reviews and App Store ratings were factored in, along with feature sets important for privacy, accessibility, and device compatibility (key strengths of ApexVision AI). All results reflect objective data, not personal anecdotes.
