Turn your English lessons into grammar quizzes with explanations
Upload PDFs, slides or notes and get multiple-choice, true/false or short-answer questions with an explanation for every answer.
Why grammar quizzes help when you learn English
Learning English grammar sticks better when you test yourself on the rules you are actually studying. DeckOwl reads your own notes, worksheets or slides and writes grammar quizzes to learn English from that material, in multiple-choice, true/false or open-answer format, with an explanation after every question.
- Multiple-choice questions on verb tenses, articles and prepositions
- True/false checks for sentence correctness with a reason for each answer
- Short-answer prompts that ask you to rewrite sentences in your own words
- Spaced review so grammar rules you miss come back before you forget them
Quizzes from your own lessons
Upload the grammar handout or notes your teacher gave you, and DeckOwl writes questions about those exact rules.
Explanations for every answer
Each question shows why the correct answer is right, so a wrong guess teaches you the rule instead of just marking you wrong.
Spaced review of tricky rules
Flashcards with spaced repetition bring back the grammar points you miss, so tense contrasts and article rules stick over time.
How it works
Upload your material
Add a PDF, DOCX, PPTX, plain text notes or a photo of a grammar page.
Choose a quiz format
Pick multiple-choice, true/false or short-answer questions for the level you are studying.
Practice and review
Answer in the browser, read each explanation, and repeat the questions you got wrong.
Generic quizzes often skip the points that cause the most trouble, such as present perfect versus simple past or when to use who versus whom. Uploading your own lesson gives you questions aimed at those exact points, and each explanation shows the rule behind the answer.
The free plan includes three generations per month and studying in the browser. Plus adds unlimited generations and exports to PDF, DOCX, Anki and CSV for offline practice, and Pro adds QTI 2.1 and Moodle XML for classroom systems.

Frequently asked questions
How many grammar questions should I practice each day when learning English?
A short daily set, such as ten questions, usually works better than one long session each week. Review every wrong answer and its explanation before moving on.
Which English grammar topics are hardest to practice with quizzes?
Tense contrasts like present perfect versus simple past, article use, and prepositions of time cause many errors. Quizzes help here because each wrong answer points to the rule you missed.
Can I export grammar quizzes for a class?
Yes, on paid plans. Plus exports PDF and DOCX files, and Pro adds QTI 2.1 and Moodle XML for learning management systems.
Do I need a credit card to try it?
No. You can start on the free plan without a credit card, which includes three generations per month and studying in the browser.
