Chegg costs $15-20 per month. For many students, that's a significant recurring expense — especially when you only need homework help during finals or for one difficult course. The good news: several free alternatives cover most of what students actually use Chegg for.
This guide ranks 7 free Chegg alternatives by what they do best. Not all are equal — the right choice depends on whether you need quiz help, textbook solutions, study materials, or math problem solving.
Why Students Look for Chegg Alternatives
Chegg Study's main value propositions are: textbook solution manuals organized by problem number, Q&A where human experts answer custom questions, and a practice problem library. At $15-20/month, it's useful — but not for every student, and not all year long.
$15
per month is the minimum Chegg Study subscription cost. Many students only need it for 1-2 months of the year but end up paying year-round.
The 7 Best Free Chegg Alternatives
1. QuizSolve — Best for Online Quiz & Homework Help
QuizSolve is a free AI Chrome extension that answers quiz questions directly on Canvas, Blackboard, Moodle, Chegg, Quizlet, Pearson MyLab, McGraw-Hill Connect, and 50+ other platforms. Double-tap any question and get an AI-generated answer with explanation in under 2 seconds — no tab switching, no subscription.
Free tier: 10 questions/day + 3 screenshot solves. Pro: $6.99/month. Best for: Students taking timed online quizzes who need instant answers without leaving the quiz page.
2. Khan Academy — Best Free Textbook Replacement
Khan Academy offers free, high-quality video explanations and practice problems for math (up to calculus), science, economics, and more. It's not a solution manual, but for understanding concepts and practicing problems, it's unmatched. Particularly strong for STEM students who need foundational understanding, not just answers.
Cost: Completely free. Best for: Building understanding from scratch, not looking up specific textbook answers.
3. OpenStax — Free Textbooks
OpenStax offers free, peer-reviewed textbooks for the most common college courses: Calculus, Biology, Chemistry, Physics, Economics, Psychology, Statistics, and many more. If your course uses an OpenStax textbook, you can access it completely free online.
Cost: Completely free. Best for: Courses using OpenStax textbooks — saves $100-200 per course.
4. Wolfram Alpha — Best for Math and Science Calculations
Wolfram Alpha is the go-to tool for step-by-step math problem solving. Plug in a calculus problem, system of equations, statistical calculation, or chemistry formula and get a detailed step-by-step solution. The free tier shows basic results; the Pro tier ($5/month) shows full step-by-step solutions.
Cost: Free for basic results, $5/month for full steps. Best for: Math-heavy courses where you need to understand solution methods, not just final answers.
5. Quizlet — Best Free Flashcard and Study Tool
Quizlet's free tier gives you access to millions of public flashcard sets covering virtually every course topic. You can also create your own sets, use Learn mode, and take practice tests. It doesn't solve textbook problems directly, but for vocabulary-heavy and definition-heavy courses, it's excellent.
Cost: Free (with ads). Best for: Memorization-heavy courses: biology terms, history dates, language vocabulary, anatomy, psychology concepts.
6. LibreTexts — Free Peer-Reviewed Textbooks
LibreTexts hosts thousands of free, peer-reviewed textbooks and learning materials in STEM fields. Similar to OpenStax but with broader coverage and more niche subjects (biochemistry, materials science, geoscience). Searchable by subject and level.
Cost: Completely free. Best for: STEM students who can't access textbooks through their library.
7. YouTube (Subject-Specific Channels) — Best for Video Explanations
For concept explanation, YouTube is underrated as a Chegg alternative. Channels like 3Blue1Brown (math intuition), Organic Chemistry Tutor (gen chem through organic), Professor Leonard (calculus), and CrashCourse (every subject) offer free, high-quality explanations. Unlike Chegg, you get the 'why' not just the answer.
Cost: Free. Best for: Students who learn better from video explanations than text solutions.
Which Alternative Should You Use?
- For timed online quizzes (Canvas, Blackboard, Moodle): Use QuizSolve — instant AI answers directly on the quiz page
- For understanding concepts: Khan Academy or YouTube subject channels
- For free textbooks: OpenStax or LibreTexts
- For math problem solving: Wolfram Alpha (free basic results)
- For memorization and flashcards: Quizlet free tier
When Is Chegg Actually Worth It?
Chegg Study is genuinely valuable in specific situations: when your instructor assigns specific problems from a textbook that has official Chegg solutions, when you need step-by-step solutions with full worked examples for math/engineering, or when you need on-demand expert tutoring for complex problems.
For most students who primarily need quiz help and concept explanations, the free alternatives above — particularly QuizSolve for quiz answering — cover most use cases without the monthly fee.
