## 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

## Studocu

Studocu is a study platform for students that revolves around a shared global library of study documents. Rather than generating everything from scratch, it relies on students themselves — when someone uploads their lecture notes, summaries, study guides or past exams, other students searching for the same course, university or topic can find them. This makes Studocu especially useful for courses where a set of well-organised notes or a previous exam is worth more than any textbook chapter. It operates across many countries with a large user base, and materials are organised by course and institution so you can narrow down to what is actually relevant to you.

On top of the document library, Studocu has added an AI layer that fits naturally into student workflows. There is a study assistant for asking questions, tools that generate notes and summaries from your documents, quiz generation and flashcards for active recall, and text-to-speech so you can listen to study material instead of reading it. Together these features turn a plain PDF of notes into something closer to a revision kit — the document provides the source, and the AI tools reshape it into summaries, practice questions and flashcards you can drill.

Studocu is a freemium service. Creating an account and previewing documents is free, but full unlimited downloads, an ad-free experience and the premium AI study features sit behind a subscription. The platform also rewards contribution: uploading your own documents and engaging with classmates earns points that can be redeemed for downloads, so active contributors can offset the cost. Because access is guarded by bot protection, automated tools and some VPN users occasionally hit a temporary access block, which is a security measure rather than an outage. Studocu suits students who want a fast route to course-specific material and a way to turn it into active study rather than passive reading.

**Pricing & Plans:** Studocu uses a freemium model. Signing up and previewing shared documents is free, while unlimited downloads, ad-free browsing and the full AI study toolkit are offered through a paid subscription. You can also earn points by uploading your own study documents and redeem them for premium access, and regional plans and prices vary, so check the official site for current details.

- **Global document library:** Search a vast, student-contributed library of lecture notes, summaries, study guides and past exams organised by course and institution.
- **AI notes and summaries:** Generate notes, summaries and revision material from documents so you can study the essentials instead of re-reading everything.
- **Quizzes and flashcards:** Turn study material into interactive quizzes and flashcards so you can test yourself and target weak spots.
- **Text-to-speech:** Use built-in text-to-speech to listen to study documents on the go, useful for revision during commutes or downtime.
- **Upload and earn points:** Upload your own documents to earn points that can be redeemed for premium download access, alongside the option to subscribe.

**Strengths:** Huge global library of real student-contributed lecture notes and past exams; AI study tools turn documents into summaries, quizzes and flashcards; Points system rewards uploading your own material and can offset premium costs; Local libraries and multilingual support across many countries

**Limitations:** Full downloads and unlimited access are gated behind a paid subscription; Bot protection temporarily blocks some visitors, which can frustrate access; Quality of user-uploaded study materials varies by course; Some regions may not be fully covered by the local document library
