## 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

## Quriosity

Quriosity is a browser extension designed around a simple idea: learning should start the moment curiosity strikes. Instead of browsing a catalog and hoping something fits, you describe your goal in a single sentence and let the tool assemble a course outline tailored to that request. The extension markets itself as an AI course creator that works across virtually any subject, from business and technology to niche personal interests.

The flow is intentionally minimal. You install the extension, open it, and type a sentence such as the subject you want to study. The AI then produces a structured course, which you can work through at your own pace. Because it does not depend on a fixed library, the same tool can cover topics that a traditional course platform would never build a dedicated track for, and it can adapt the difficulty and language to the learner.

Quriosity is distributed through the Chrome Web Store and is free to use, with the listing describing unlimited, no-cost course generation. The developer also points users to a companion website and a Google Play app. It is aimed at self-directed learners, professionals topping up a skill, and anyone who wants a fast starting point for an unfamiliar subject.

**Pricing & Plans:** Listed as Free. The Chrome Web Store listing describes unlimited, no-cost course generation; no paid tier is published on the store page.

- **One-sentence course creation:** Describe what you want to learn in a single sentence and receive a structured course generated around that request.
- **Any topic, any language, any level:** Because courses are generated rather than drawn from a fixed catalog, the tool can cover a huge range of subjects and adapt to different languages and difficulty levels.
- **Personalized learning paths:** Generated content is tailored to the interests and goals you express, so the course reflects your own objective rather than a generic syllabus.
- **Runs inside Chrome:** Delivered as a lightweight browser extension, so course generation is available from the toolbar without switching to a separate web app.
- **Free to use:** The listing advertises unlimited course generation at no cost.

**Strengths:** Extremely fast path from curiosity to a course outline; Covers very broad subject matter with no fixed catalog limits; Supports multiple languages and learner levels; Free to install and use as a Chrome extension

**Limitations:** Very small user base and few reviews on the store listing; Course quality depends entirely on the underlying AI output; Some users may prefer human-curated courses with accreditation
