Turn your notes into used to quizzes with AI
Upload a grammar chapter, class slides or photos of handwritten notes. DeckOwl writes practice questions with explanations, so you can check where your used to sentences break down.
Why practice quizzes on used to work better when they come from your own notes
Most people searching for quizzes about used to want a quick way to check whether they really understand the pattern, not a generic worksheet. DeckOwl builds that from your own material: upload a grammar chapter, class slides or notes photographed on your phone, and get multiple-choice, true/false or short-answer questions with an explanation for each one.
- Multiple-choice, true/false and short-answer questions from any PDF, DOCX, PPTX, text or photo of notes
- Explanations that point to the rule behind each correct answer
- Spaced repetition and flashcards for the forms you keep mixing up
- Exports to PDF, DOCX, Anki and CSV on Plus, with QTI 2.1 and Moodle XML on Pro
Questions from your own material
Upload PDF, DOCX, PPTX, plain text or photos of pages. The AI writes multiple-choice, true/false and short-answer questions based on what you actually studied.
Explanations for every answer
Each question comes with a short explanation, so a wrong answer shows you the rule, such as when used to takes a base verb and when a question switches to did you use to.
Study in the browser or export
Free accounts study in the browser with 3 generations per month. Plus adds unlimited generations and exports to PDF, DOCX, Anki and CSV.
How it works
Upload your notes or slides
Add a PDF, DOCX, PPTX, text file or photos of your pages. No credit card is needed to start.
Choose question types
Pick multiple-choice, true/false or short-answer questions, or mix them for a fuller practice set.
Practice and review misses
Answer the questions, read the explanation for each miss, and come back to the same set later to see what stuck.
The explanations are the useful part. They show why used to takes a base verb, why it describes past habits that no longer happen, and why questions switch to did you use to. Work through a set, read the explanation for every miss, then return to those questions a few days later to test what you kept.

Frequently asked questions
How do I tell used to apart from be used to?
Used to plus a base verb describes a past habit or state that no longer applies, as in I used to walk to school. Be used to plus -ing or a noun means you are familiar with something, as in I am used to waking early.
How many practice questions should I write for a unit on used to?
A short, focused set usually works better than a long one. Mix fill-in-the-blank, error correction and true/false items, and repeat the ones you miss across several sessions.
What file types can I upload?
You can upload PDF, DOCX, PPTX, plain text notes, and photos of pages, which are read with text recognition. Images of handwriting work best when the text is clear and well lit.
Can I export the quizzes I generate?
Plus includes export to PDF, DOCX, Anki and CSV. QTI 2.1 and Moodle XML export are available on the Pro plan.
