Tutor AI builds a full custom course (lessons, quizzes, flashcards) on any topic you pick, while StudyX works from your own homework, PDFs, slides and lectures to give step-by-step solutions, notes and quizzes. Choose Tutor AI to learn something new from scratch, and StudyX to get through the coursework you already have.
Tutor AI is a "start from a topic" tool. You pick a subject, level and goal, and it generates a course with lessons, quizzes, flashcards and study materials, then lets you ask questions and get explanations and examples at your own pace. It covers academic subjects like math, science and languages as well as work skills and hobbies, and also has an AI homework helper and a progress dashboard. The company also sells versions for educators and corporate or white-label training.
StudyX is a "start from your material" tool. You upload or paste a homework question, photo, PDF, slide deck, video or live lecture, and it returns step-by-step solutions across 50+ subjects, or turns the material into organized notes, flashcards with spaced repetition, and practice quizzes. It also includes a writing set with an AI detector, plagiarism checker, paraphraser and humanizer.

Pros: generates a custom course with lessons, quizzes and flashcards on almost any topic in seconds; includes an AI homework helper; has a free plan and low-cost yearly billing; offers educator and corporate versions.
Cons: the free plan is limited with limited support; spaced repetition and the flashcard dashboard are reserved for the Genius plan; AI-generated courses can contain mistakes, so check important material such as exam content against a trusted source.
Pricing: Free plan to try; Mentor $13.33/mo billed yearly; Genius $17.50/mo billed yearly; yearly billing saves up to 30%.
Best for: self-learners, professionals and students who want a structured course on a subject they have not studied yet.
Pros: turns your own homework, PDFs, slides, videos and lectures into solutions, notes, flashcards and quizzes in one place; free to start with no sign-up; step-by-step solutions aim to explain the method; writing checks sit alongside the study tools.
Cons: credit-based plans mean heavy users can run out (Plus includes 3,000 credits a month); the money-back guarantee is only 3 days; tools like the humanizer and homework answer generator can conflict with school rules on AI use, and AI solutions can be wrong.
Pricing: Free to start; Plus $9.99/mo ($5.83/mo billed annually); Pro $19.99/mo ($8.92/mo billed annually); Max $99.99/mo ($59.92/mo billed annually).
Best for: high school and college students who want homework help, notes, flashcards and practice quizzes built from their own course material.
Pick Tutor AI if you are learning a topic from zero, such as machine learning fundamentals or intermediate French, and want a structured path. Pick StudyX if you already have assignments, slides and recordings and need help getting through them. The two overlap on homework help and flashcards, so you rarely need both; if you are unsure, start with the free option of each and see which matches how you study.
Skip both if your school or course bans AI assistance, since submitting AI-generated answers can count as academic misconduct. Skip StudyX's humanizer and answer-generation features if your goal is real understanding rather than finished homework. And skip either one for exam-critical material unless you verify the answers against your textbook or teacher, because AI explanations can be wrong.

Is Tutor AI or StudyX cheaper? On annual billing StudyX Plus ($5.83/mo) is cheaper than Tutor AI Mentor ($13.33/mo), but the plans include different things, so compare what you actually need.
Can I use either tool for free? Yes. Tutor AI has a free plan with no card required, and StudyX is free to start with no sign-up. Both limit what the free tier includes.
Which is better for exam prep? StudyX builds quizzes and flashcards from your own course material, while Tutor AI builds them from a course it generates. Verify either against your syllabus.
Will my school accept AI-generated answers? It depends on your institution. Check its policy on AI use before submitting anything produced with either tool.
