What separates the best free homework help sites?
All five picks were tested with the same 30 questions, graded by teachers. The scores split them by subject and by how much hand-holding you want.
Khan Academy scores 8.8 and costs nothing. Teachers graded its calculus and chemistry explanations highest, and Khanmigo walks you through steps instead of handing over the answer. It has no textbook-specific solutions, and humanities help is thin.
Quizlet sits at 8.2 for $7.99. Learn mode schedules review, practice tests generate themselves, and Magic Notes turns uploaded notes into cards. Its 500 million study sets are user-made, so errors show up, and textbook solutions are thinner than Chegg's.
Photomath, owned by Google since 2023, scores 7.7. It solved 19 of our 20 math and chemistry-math questions correctly with steps, and the free tier covers most homework. It is math only, and word problems and proofs are hit and miss.
Grammarly scores 7.1 at $12. It caught grammar, clarity and tone issues in our essay answers that teachers also flagged, with a citation generator and plagiarism check on Pro. It handles writing only.
Brainly is the cheapest at $3.99 and the lowest scorer at 6.5. Answers to common questions already exist and the verified-answer badge helps, but teachers flagged several confidently wrong answers.
What should you check before buying?
Our scoring weights answer quality at 30, coverage and study tools at 20 each, value at 20, and learning and integrity at 10. Match that to your subject.
- Math and science: step-by-step explanations matter more than a library. Photomath and Khan Academy both show work.
- Essay subjects: Grammarly is the only pick built for writing, but its AI rewrite features blur the line on academic integrity.
- Memorisation: Quizlet's Learn mode adapts, but check user-made sets for errors.
- Budget: Khan Academy and Photomath's free tier cost nothing; Brainly's free tier is usable.
