## 101.school

101.school is a browser-based learning platform built around a simple premise: if you can name a topic, you can get a course on it. Visitors type in whatever they want to teach themselves, and the tool produces a structured, multi-week curriculum — complete with lessons, sequencing and a title — in seconds. It blends an on-demand generation engine with a catalogue of featured courses that other learners have already created and published.

The site doubles as a browsable directory. Its featured shelves span Sciences and Mathematics, Engineering and Technology, Business and Management, Arts and Communication, Social Sciences, and Personal Services, Health and Safety, among others. Courses range from hobbyist topics such as coffee brewing, chess or beer brewing to professional subjects like payroll management, property and casualty insurance, system design and malware analysis.

Because access is free and no account wall blocks the generator, 101.school works well as a lightweight self-study companion. Course pages are lightweight and readable, and the built-in search and keyboard command palette make it quick to jump between subjects. It is aimed at self-directed learners, career switchers and anyone who prefers a short, structured sprint over an open-ended pile of links.

**Pricing & Plans:** 101.school is free to use, including AI course generation, with no visible subscription tiers.

## Periplus

Periplus starts from a prompt: type a topic, ask a question or drop in a PDF, and it generates a full course with chapters that build on one another. Lessons link to related documents, so you can open two side by side or follow a graph of connected ideas. Every lesson can branch into a new course, letting you drill into a detail without losing your place. Anything you open is stored in a personal library that is searchable and resumable, and new courses can pick up where your existing knowledge ends.

Learning support is built into the flow rather than bolted on. Each lesson can convert into flashcards and quizzes, which resurface on a spaced schedule timed to appear just before you would forget. Courses can also be turned into podcast episodes: two AI hosts walk through the chapters, captions follow the audio word by word, and you can raise your hand to ask a question mid-episode. Lessons can include maps, diagrams and worked math. On the Premium tier, deep research pulls in web sources you can open yourself, and PDF-based courses build the curriculum around your own material.

Periplus is explicit about its difference from ChatGPT: instead of you deciding what to study next, the platform lays out the curriculum, tests you as you go, and guards against hallucinated content by checking lessons before they are shown. It supports multiple languages, chosen at signup or changed in settings, and generates everything in the selection. There is a free plan with no credit card required for creating courses and taking quizzes.

**Pricing & Plans:** Freemium. The free plan covers course creation and quizzes without a credit card; Premium removes usage limits and adds features such as PDF-based course generation and deep research with web sources.

- **AI course generation:** Type a topic or question and get a chapter-by-chapter course, with any lesson able to branch into a new, linked course.
- **Spaced-repetition flashcards and quizzes:** Any lesson converts into flashcards and quizzes that return on a schedule timed for just before you would forget.
- **Course-to-podcast audio:** Each chapter becomes a podcast episode hosted by two AI voices, with word-level captions, transcripts and the ability to ask questions out loud.
- **Linked knowledge graph:** Documents link to related lessons so you can compare side by side or follow connections across subjects.
- **PDF-based learning:** On Premium, upload a lecture or paper and Periplus builds a course around it, or lets you chat with the document directly.

**Strengths:** Structured courses rather than unstructured chat answers; Flashcards and quizzes scheduled with spaced repetition; Podcast format with captions lets you learn hands-free; Free plan available and no credit card required to start

**Limitations:** PDF upload and deep research are limited to Premium; Course quality depends on the AI's source coverage for niche topics; Everything is AI-generated, so critical reading is still advised
