Why build your own deck instead of searching for one

Hunting through shared decks for Anki flashcards often turns up cards written for a different textbook, edition or course. Gaps and mismatched terms slow you down before you even start studying.

  • Cards are drawn from your own PDFs, slides, notes or photos of pages.
  • Spaced repetition schedules reviews based on how well you recall each card.
  • The Free plan includes 3 generations per month and browser study, with no exports.
  • Plus at $99.90/year or $9.99/month adds unlimited generations and Anki export.
Example search algorithm flashcards to study
Time complexity of binary search on a sorted array?O(log n), because each comparison halves the remaining range.
Which data structure does breadth-first search use?A queue, which visits nodes level by level in first-in, first-out order.
Which data structure does depth-first search use?A stack, either explicit or the call stack through recursion, which goes deep before backtracking.
Why must the input be sorted for binary search?Binary search discards half the range by comparing with the middle element, which only works when the order is known.
How does A* search differ from Dijkstra's algorithm?A* adds a heuristic estimate of the remaining cost to guide the search toward the goal.
Generate the full set

Built from your material

Upload PDFs, DOCX, PPTX, plain text or photos of pages. The cards cover what your professor actually taught.

Spaced repetition

Cards come back at the intervals where you are most likely to forget them, so review time goes to the hard ones.

Export to Anki

On Plus, export your deck to Anki, plus PDF, DOCX and CSV. The Free plan studies in the browser.

How it works

Upload your source

Add a PDF, slide deck, document, notes or a photo of a page.

Generate flashcards

DeckOwl writes question-and-answer cards from the text in your file.

Study and review

Work through the deck in the browser, or export to Anki on Plus and keep the spaced schedule going there.

A custom deck starts from the document you are actually tested on. Upload the lecture slides or chapter PDF, and the generator pulls out the terms, definitions and relationships in that material. You can then review the cards, delete the weak ones and study on a spaced repetition schedule.

Generating your own cards also helps with retention. Reading the source and checking each card against it is part of the learning, so the deck becomes a record of what you were taught.

Frequently asked questions

How do I study binary search for an exam?

Learn the idea of halving the search range on a sorted array, then trace a few searches by hand. Practice stating the O(log n) running time and the condition that the input must be sorted.

What is the difference between breadth-first and depth-first search?

Breadth-first search explores nodes level by level using a queue, while depth-first search goes as deep as possible along one path using a stack or recursion. Breadth-first finds shortest paths in unweighted graphs, and depth-first is often used for exploring structure.

Can I export my flashcards to Anki for free?

No, export to Anki is a paid feature included in Plus, which costs $99.90/year or $9.99/month. The Free plan lets you study your cards in the browser with 3 generations per month.

Do I need a credit card to start?

No, you can start on the Free plan without adding a credit card. Students also get 40% off with a school email.
