Why Anki deck performance depends on the cards you start with
Your Anki deck performance is only as good as the cards behind it. Anki's statistics show retention, lapses and upcoming workload, but none of those numbers help if the deck came from a rushed highlight pass through a textbook.
- Retention rate: the share of reviews you answered correctly, shown in Anki's statistics
- Lapses: how often a review card was forgotten and sent back into relearning
- Due forecast: the number of reviews scheduled for each upcoming day
- Ease: the multiplier Anki applies to a card's interval after a correct answer
Upload your source material
PDFs, DOCX, PPTX, plain text notes and photos of pages all become flashcards built from your own material.
Spaced repetition built in
Cards are scheduled at increasing intervals, so the cards you forget come back sooner and the ones you know wait longer.
Export to Anki on Plus
Plus exports your generated cards to Anki, so your review history and statistics live where you already study.
How it works
Upload notes or slides
Add a PDF, DOCX, PPTX, text file or image of a page to start a new set of flashcards.
Study the generated cards
Review the flashcards in your browser while spaced repetition schedules each card for its next review.
Export the deck to Anki
On Plus, export the cards to Anki and read retention, lapses and due counts in Anki's own statistics.
DeckOwl starts from your own material. Upload a lecture PDF, slides, or a photo of handwritten notes, and it generates flashcards with spaced repetition scheduling, so the cards you review match what your material actually teaches.
Once the deck is in Anki, watch the retention rate and lapse count over a few weeks. Cards that keep lapsing often need a clearer question or a smaller fact, and rewording them is usually faster than studying them harder.

Frequently asked questions
Which Anki statistics matter most when judging a deck?
Retention rate and lapse count are the two to watch first. A high retention rate with few lapses suggests the cards are clear and being reviewed on schedule.
How many flashcards should I make for one lecture?
There is no fixed number, but most lectures support a focused set of cards for each key concept. Start with the main definitions and processes, then add cards for facts you keep missing.
Can DeckOwl show my Anki performance inside the app?
DeckOwl generates the cards and schedules them with spaced repetition, and you can study them in the browser. Performance statistics come from Anki after you export the deck.
Do I need to pay to get my deck into Anki?
Yes, exporting to Anki is a paid feature. Plus costs $39/year or $7.99/month, and students get 40% off with a school email.
