Turn your biology notes into a practice quiz with AI
DeckOwl does not make videos. It reads your lecture slides, notes or textbook photos and writes a quiz you can answer in the browser, with an explanation for every question.
Why a quiz built from your own notes beats a generic video
A video cannot test you on the exact diagrams and terms your instructor used, but a biology quiz built from your slides can.
- Questions drawn only from the files you upload
- Explanations that show the reasoning behind each correct answer
- Quizzes you can take in the browser on any device
- Exports to PDF or DOCX on Plus, and QTI 2.1 or Moodle XML on Pro
Multiple-choice, true/false and open questions
Pick the question style that fits the topic, from quick true/false checks on terms to short-answer prompts on processes like cellular respiration.
Explanations for every answer
Each question shows why the correct answer is right, so a missed question about enzyme function or Mendelian ratios becomes a lesson.
Reads the files you already have
Upload a PDF, DOCX, PPTX, plain text or a photo of a page, and DeckOwl recognizes the text and builds questions from it.
How it works
Upload your biology material
Add a lecture PDF, a slide deck, lab notes or a photo of a textbook page.
Choose the question types
Select multiple-choice, true/false or open questions, then generate the quiz.
Answer and review
Work through the quiz in your browser and read the explanation after each answer.
Upload a PDF of your lecture, a DOCX of lab notes, a PPTX deck or a photo of a textbook page. DeckOwl reads the text and writes multiple-choice, true/false or open questions. Each answer comes with an explanation, so a wrong guess teaches you the reason behind the right one.
The free plan includes 3 generations per month and studying in the browser. Plus adds unlimited generations and PDF and DOCX exports, and Pro adds QTI 2.1 and Moodle XML export for courses that run on those systems.

Frequently asked questions
How often should I quiz myself on biology topics?
Short quizzes spread across several days usually work better than one long session. Retesting a topic a day or two after you first learn it helps the material stay in memory.
Why do explanations matter for biology questions?
Many biology questions test cause and effect, such as why a mutation changes a protein's shape. Reading the explanation after a wrong answer shows the chain of reasoning you need for the exam.
Can I export a biology quiz to PDF or Moodle?
PDF and DOCX export are included in Plus, which costs $39 per year or $7.99 per month. QTI 2.1 and Moodle XML export are included in Pro at $14.99 per month.
Do I need a credit card to try it?
No. You can start on the free plan without a credit card, which includes 3 generations per month and studying in the browser.
