An AI quiz generator that remembers what you missed
Winda writes multiple-choice questions from your PDFs, articles, and videos, so you find out what you didn't understand while the material is still open. The questions you miss come back sooner.
Practice questions from your own material
Written from what you're reading
Questions are about what is actually in the document you're reading, and each one links back to where it came from.
Quiz yourself mid-chapter
Select a passage in the reader and turn it into a question on the spot, so checking your understanding doesn't wait until the end.
One answer or several
Every question offers two to six options. Some have a single right answer and grade the moment you pick one; others ask you to select every option that applies.
Get it wrong and it comes back sooner
Each question carries its own review date. Answer it right and the gap widens; answer it wrong and it returns while it still needs the work.
How it works
Read a section
Open the PDF, article, or video and read it as you normally would.
Get asked about it
Select the passage you just finished, or generate from the whole document. Keep the good ones and edit the rest.
Answer them over time
Add a question to practice and it gets a review date. Winda shows you what is due each day: the ones you know drift further apart, the ones you don't stay close.
Where a quiz beats another read-through
Anywhere rereading feels productive and turns out not to be.
Certification exams
The CFA Level I exam is all multiple choice, and its curriculum runs to thousands of pages. A few questions at the end of each reading show whether you can apply it or only recognize it.
Coursework and lectures
Turn this week's slides and readings into exam-style questions while there is still time to go back to what you get wrong.
Video courses
Paste a lecture from YouTube and get questions from what was said, so watching becomes something you can check.
Training and compliance
Onboarding material and compliance training you will be checked on. A quiz before the real check shows what you would miss.
Frequently asked questions
Web articles, YouTube videos, PDFs, Word documents, slide decks, images, and your own text. Generate from a whole document or from a passage you select.
Multiple choice with two to six options, either with one correct answer or with several that all have to be selected. For open recall, the same material can become flashcards instead. Every question, option, and answer key is editable.
No. Winda writes questions only from the material you give it, so it covers what you have read and nothing else. For an exam, use it alongside your prep provider's question bank: the bank shows the exam's style across the whole syllabus, and Winda checks the readings you just finished.
Yes. Generating questions uses monthly credits, and the Free plan includes some every month. Answering and reviewing questions never costs credits.
