Its pitch is consolidation: rather than juggling several apps, students upload their class materials once and get flashcards, notes, summaries, and practice tests generated in one place. Importing existing Quizlet sets takes a couple of clicks, including images and formatting. The AI layer is powered by Kai, an assistant that works across PDFs, slides, images, videos, and live lecture recordings. Uploading files produces notes, flashcards, and quizzes automatically, and Kai can also answer questions about your materials and explain why a practice answer was wrong. An Exam Predictor and Planner builds a study schedule from uploaded course files, while Voice Tutoring & Podcasts let students be quizzed aloud or turn notes into audio for studying on the go. Knowt is free to use for core studying, with unlimited learn mode and free practice tests. It is widely adopted in education, with millions of students and teachers using it and a strong presence in AP exam preparation, alongside SAT and ACT resources and a Chrome extension for on-screen study. **Pricing & Plans:** Knowt's core features are free: unlimited learn mode, free practice tests, flashcard creation, imports, and AI study tools with reasonable usage limits. Optional paid upgrades (Plus/Unlimited-style tiers) unlock higher AI generation limits and premium features.

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 Knowt and Periplus compare in monthly traffic?
