The site says it will "describe a topic and get an AI-made course with slides and quizzes," so instead of sifting through long videos or articles, you get a structured sequence of bite-size slides interleaved with quiz questions. Each course is designed to be consumed "one swipe at a time," which keeps sessions short and focused — a natural fit for active recall and spaced review on a phone. Beyond generating from a topic, didacu supports working from your own material, so a document or source text can become a course with slides and check-your-understanding quizzes. The homepage also surfaces a library of featured, publicly shared courses spanning subjects like astrophysics, pharmacology, constitutional law, circuit analysis, MBA essentials, NCLEX pharmacology, data structures and algorithms, cognitive psychology, SEO and growth marketing, and financial reporting — each published as a shareable course page. Because the output is slide-and-quiz based rather than a video or a chat transcript, didacu occupies a niche between AI course generators, AI quiz makers and AI lesson-plan tools. It targets students, exam candidates and self-directed learners who want to convert a topic or document into structured, testable study material quickly. **Pricing & Plans:** didacu uses a freemium model: you can generate and study courses for free, with paid options for expanded use.

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 [Profile (Markdown)](https://openaitools.app/tool/periplus.md) ## Frequently Asked Questions ### How do didacu and Periplus compare in monthly traffic? didacu has 0 monthly visits, while Periplus has 27,280.
