Chegg

Chegg is a long-established online education company best known for homework help, textbook solutions and study support used by millions of college students. Its core offering, Chegg Study, gives students access to step-by-step solutions for textbook problems, a library of expert-answered questions, and the ability to ask subject experts new questions and get worked solutions — a lifeline for students stuck on problem sets at 2am.

Chegg has been integrating AI to modernize its help, offering faster AI-generated explanations alongside its expert-answer model, plus tools for writing, math and citations. Beyond study help, Chegg offers textbook rentals (a major cost-saver versus buying), online tutoring, and career resources.

Pricing is subscription-based: Chegg Study runs around $15.95/month, with bundles (Chegg Study Pack) adding writing tools, math solving and more for a higher monthly fee. There's no meaningful free tier for the core solutions.

Strengths: an enormous library of textbook solutions (someone has likely answered your exact problem), expert human answers for tricky questions, and useful textbook rentals. Weaknesses: subscription cost adds up for students on tight budgets, its business faces disruption from free AI tools like ChatGPT doing similar work at no cost, and — significantly — many universities treat unauthorized use of Chegg solutions during exams as academic misconduct, so use it to learn, not to cheat.

For students who want worked solutions and expert help with genuinely difficult coursework, Chegg remains popular — though free AI assistants now handle much of what students once paid for.
