3 decisions
How to choose AI Study Assistants tools
Some cover every subject; others focus on one area. The main difference to look for is whether a tool explains its reasoning or just hands you an answer.
EduSolver, Math AI, and EduBrain.ai all walk you through each step rather than stopping at the result. AskTutor is free with no account required and covers STEM alongside other subjects. Crackr AI is the only tool here with no free plan; it sells one-time credit packs starting at $19 and focuses entirely on coding interview practice. Tutor AI lets you build a custom tutor for any subject, while RemNote pairs note-taking with flashcards and a built-in review schedule.
Which subjects does the tool cover
Most tools here handle a broad range of subjects. EduBrain.ai covers maths, physics, biology, statistics and more, and accepts photos, PDFs, screenshots and long notes. AskTutor reports that 86% of its users come for maths and science, but it supports all classes. Math AI stays within maths, from basic arithmetic to calculus and differential equations, and reads photos of handwritten problems. Crackr AI covers only coding interview topics, with study plans and a live coding environment. If your subject is anything outside maths or coding, EduBrain.ai, AskTutor, EduSolver or Tutor AI are the broader choices.
Does the tool explain its reasoning or just answer
Step-by-step reasoning is what separates a study tool from a shortcut. EduSolver, Math AI, and EduBrain.ai all break problems into steps modelled on how a tutor would explain them. Tutor AI does the same and lets you build a subject-specific tutor that can handle images of equations or diagrams. AskTutor adapts its explanations to your pace. Crackr AI goes further for coding: it switches between teaching mode and interview simulation so you can practise explaining your own reasoning out loud. Tools that only return a final answer are not represented here; every tool in this group shows its working to some degree.
What does the free plan actually let you do
Seven tools here have a free plan, but the limits vary. AskTutor is free with no account needed, and its PDF chat is also free. EduSolver has a free tier; advanced features move to a PRO plan priced on request. Math AI's free plan limits the number of problems you can solve each day through a credit system; paid plans start at $3.90 a month billed annually. EduBrain.ai gives free attempts before asking you to register, then charges $3.99 a week on its paid plan. Tutor AI is free to start and charges $4.99 a month for its premium plan. Crackr AI has no free plan at all; the cheapest option is a one-time $19 starter pack.
