## 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

## Tool LoR

Tool LoR is a compact browser add-on aimed at learners who grind through web-based language exercises — the kind where you complete fill-in-the-blank sentences, listen to audio prompts, and click through one question after another. Instead of repeating every manual step, the extension takes over the repetitive parts: it inserts the missing word, auto-plays the audio card attached to a question, and automatically moves to the next item once the current exercise is marked complete. Along the way it can store the new vocabulary it encounters so you can revisit it later, and an adjustable timer lets you control the pace at which exercises advance.

The extension is distributed only through the Chrome Web Store and is built by an individual developer (Trần Thành), so it has a small, focused user base and a narrowly scoped feature set rather than the polish of a commercial edtech suite. It ships in Vietnamese and is clearly designed for learners studying on specific web platforms where exercises are served one screen at a time. Because it is free and independently maintained, the experience is best treated as a convenience layer on top of your existing coursework, not as a replacement for actual study.

If you use it, review what permissions it requests and how it handles page content; the developer's listing states it reads website content to detect exercises but does not sell data or use it for unrelated purposes. As with any unofficial study aid, always follow your course or institution's rules about automated assistance.

**Pricing & Plans:** Tool LoR is free to install and use from the Chrome Web Store. There is no paid tier advertised, and any optional support or donation arrangements are handled by the developer directly.

- **Automatic cloze filling:** Inserts the missing word into fill-in-the-blank sentences so you can move through exercises faster.
- **Audio card auto-play:** Plays the audio attached to flashcard-style questions automatically, without a manual click each time.
- **Auto-advance on completion:** Detects when a question is finished and moves to the next exercise for you.
- **Vocabulary storage:** Keeps a record of the new words you meet during exercises so you can review them again later.
- **Adjustable timing:** Lets you change how long the tool waits before advancing, so you can control the pace of a study session.

**Strengths:** Completely free to install from the Chrome Web Store; Handles the repetitive parts of web-based exercises automatically; Saves new vocabulary without extra note-taking; Adjustable timing gives control over how fast exercises advance

**Limitations:** Very small user base and limited public documentation; Interface and listing are in Vietnamese only; Narrow feature set tied to specific exercise platforms
