## Course Hero

Course Hero's core asset is scale. The platform hosts well over a hundred million study documents covering courses at more than a hundred thousand colleges and high schools, from lecture notes and past exams to textbook solution sets. Students search by school and course, or paste a question and get matched to a relevant document. A Q&A layer adds millions of answered questions, many solved by verified experts with published explanations.

Around that library Course Hero has layered study tooling aimed at the moment a student is stuck. The AI Homework Help flow returns explanations rather than bare answers; a math solver walks through steps; and a 24/7 tutor channel lets students submit a question to a live expert and receive a worked response within minutes. Additional writing utilities — grammar checker, paraphraser, proofreader, spell checker — and an integrated set of third-party study tools (Quillbot, Symbolab, textbook solutions) round out the subscription.

The business model is freemium-to-premium: browsing and searching are open, while document unlocks, unlimited AI answers, textbook solutions, and tutor questions sit behind a Premium tier. Course Hero also takes academic integrity seriously, publishing community guidelines, an honor code, and a copyright policy, and reminding users that uploaded material must respect those rules.

**Pricing & Plans:** Freemium. Searching, browsing, and some previews are free. Full document unlocks, unlimited AI-powered answers and explanations, tutor questions, and textbook solutions require a Premium subscription; a limited free or trial access path is typically offered for new users. Exact plan prices vary by term length.

- **Massive study document library:** Search by school and course to reach lecture notes, study guides, past exams, and assignment solutions shared by students at thousands of institutions.
- **AI Homework Help:** Submit a question and get AI-generated explanations and recommended study content rather than an unexplained final answer.
- **24/7 verified tutors:** Ask a tutor at any hour across core subjects and receive a worked, expert-checked response, usually within minutes.
- **Textbook solutions and step-by-step math:** Work through textbook problems and math questions with structured, step-by-step solutions rather than answer keys alone.
- **Writing and grammar tools:** Built-in grammar checking, paraphrasing, proofreading, and spell checking help polish submitted work before it goes out.

**Strengths:** Extremely large, course-specific document library across many institutions; Multiple ways to get unstuck: AI explanations, math steps, and live tutors; Tutor access is genuinely 24/7, which matters near deadlines; Bundled writing and citation utilities add practical value beyond documents

**Limitations:** The most useful actions sit behind a Premium subscription; Material is student-uploaded, so quality and accuracy vary between documents; Must be used within academic integrity rules; uploading or using others' work improperly carries consequences

## Explainy

Explainy brings instant explanations into the browser. Instead of opening a new tab to search a term, you highlight a word or phrase on any page and let the extension explain it. Two modes cover different needs: 'Brief Mode' returns a quick, succinct summary for when you just need the gist, while 'Extensive Mode' gives a fuller, more in-depth explanation when you want to actually understand a concept.

The extension is designed to sit quietly in the background. It requests minimal permissions, is deliberately unobtrusive, and is intended not to interrupt your reading workflow. That makes it especially handy when you are working through study material, research papers or technical documentation and keep hitting terms that stop you in your tracks.

The Chrome Web Store lists Explainy at version 2.0.0 (published January 2024), rated 5.0 with a small user base, published by the team behind explainy.co. The developer states that it does not collect or use your data, and the extension is free to use with English-language output.

**Pricing & Plans:** Free. Explainy is offered at no cost, with no subscription tiers or paid add-ons advertised on its Chrome Web Store listing.

- **Highlight to explain:** Select a word or phrase on any page and have Explainy return an explanation instantly, without leaving the page or opening a search tab.
- **Brief Mode:** A quick, succinct mode for when you only need a short definition or the gist of a term.
- **Extensive Mode:** A more detailed mode that explores a concept in depth for when a one-line answer is not enough.
- **Privacy-conscious permissions:** Explainy operates with minimal permissions and the developer declares that no user data is collected or used.
- **Unobtrusive by design:** The extension sits discreetly in the browser so explanations are available without interrupting your reading flow.

**Strengths:** Free to use with no subscription required; Two explanation depths let you choose speed or detail; Minimal permissions and a no-data-collection declaration; Unobtrusive, so it fits naturally into your browsing workflow

**Limitations:** Output is English-only per its Chrome Web Store listing; Last updated in early 2024, so it may lag behind newer AI capabilities; Very small user base and limited public documentation
