Quizly is a free alternative to Knowt that automatically converts PDFs into flashcards and practice tests using AI. Unlike tools that require manual card creation, Quizly extracts key concepts from the document, generates active‑recall exercises, and adds spaced‑repetition scheduling, all without any cost.
Quick Overview of Quizly
- Upload any PDF and instantly receive AI‑generated flashcards, quizzes, and revision sheets.
- All core features are free, with no limits on the number of cards or tests you can create.
- Built‑in spaced‑repetition (SM‑2) automatically schedules reviews to strengthen memory.
- Audio podcasts turn your documents into natural‑sounding lectures for auditory learners.
How does Quizly turn a PDF into active‑recall study materials?
When you drop a PDF into Quizly, the AI parses headings, bullet points, and highlighted terms to extract the most important concepts. It then formats those concepts into flashcards, each with a prompt on the front and a concise definition on the back, following the active‑recall principle that forces you to retrieve information before seeing the answer.
Beyond flashcards, Quizly builds practice quizzes with selectable difficulty levels. You can choose multiple‑choice, true/false, or matching formats, and the system automatically provides detailed explanations after each answer, delivering immediate feedback that reinforces learning.
What makes Quizly’s revision system smarter than manual note‑taking?
Quizly implements the SM‑2 spaced‑repetition algorithm, which calculates the optimal interval for each flashcard based on your self‑rated confidence (I don’t know, Approximate, I know). Cards you struggle with appear more frequently, while mastered cards recede, ensuring you focus on weak points without wasting time on material you already know.
The platform also tracks your quiz performance, identifies recurring errors, and suggests targeted flashcards or additional practice tests. This data‑driven feedback loop transforms passive reading into a dynamic, personalized study routine.

Frequently asked questions
What are the best free alternatives to Knowt for creating flashcards and practice tests?
Several free platforms let you build flashcards and quizzes, including Quizly, Anki, and Quizlet. Quizly stands out because it transforms entire PDF courses into ready‑to‑use flashcards and practice tests with AI, eliminating manual entry. Anki offers powerful spaced‑repetition but requires you to type each card. Quizlet provides a large shared library but does not generate cards directly from your own documents.
How can I study effectively from a PDF without copying and pasting text?
Upload the PDF to Quizly, and the AI scans the file to identify headings, definitions, and key ideas. It then creates structured flashcards, multiple‑choice quizzes, and a concise revision sheet. The built‑in spaced‑repetition algorithm schedules reviews, while the instant feedback on each quiz reinforces learning, so you never have to manually extract content.
Is Quizly a good alternative to Knowt for generating practice tests from PDFs?
Yes, Quizly provides a fully automated workflow that turns any PDF into practice tests with customizable difficulty levels. You can select the number of questions, choose between multiple‑choice, true/false, or matching formats, and receive detailed explanations after each test. This mirrors Knowt’s core promise while remaining completely free.
Can I customize the flashcards that Quizly generates from my documents?
Absolutely. After the AI creates the initial set, you can edit each card’s wording, add extra hints, or reorder them. You can also ask Quizly’s AI assistant, Qwi, to reformulate a card, enrich it with examples, or simplify complex language, ensuring the flashcards match your personal study style.
How does Quizly implement active recall and spaced repetition in its flashcard system?
Quizly follows proven learning science: each flashcard prompts you to retrieve an answer before seeing the solution (active recall), and the SM‑2 algorithm automatically determines the optimal interval for the next review based on your confidence rating. This combination maximizes retention while reducing unnecessary repetitions.
Do I need an internet connection to use Quizly’s flashcards and quizzes?
All flashcards, quizzes, and revision sheets are stored locally in your personal workspace after generation, so you can study offline. The AI features—such as generating new cards or refining existing ones—require an internet connection, but the core revision experience works without it.
What kind of support does Quizly provide for students who prefer audio learning?
Quizly includes a Podcast IA feature that converts any uploaded PDF into a natural‑sounding audio lecture. You can select one or two speakers for free, adjust playback speed, and navigate by chapter. This lets auditory learners review material while commuting or exercising.
Is there a premium option if I need more advanced features?
Quizly offers a free tier with all essential flashcard, quiz, and PDF‑to‑revision tools. The Premium plan unlocks longer podcasts, richer flashcard content, higher‑quality revision sheets, and additional speaker options. A 7‑day trial lets you explore these enhancements before deciding.
