AnkiDecks

Image occlusion cards are the most specific thing AnkiDecks generates, and the free plan gives you 5 of them a month.

AnkiDecks is an AI flashcard maker that builds Anki decks from your notes and PDFs and lets you share the decks with others.

It is also tagged for quiz generation and YouTube summaries, though documents look like the natural starting point.

The free Basic plan allows 4 deck generations a month, 4 pages per document and 8,000 characters per document.

That is enough to test a short handout, not a full textbook chapter.

Pro costs $5 a month billed yearly at $60, or $7.99 billed monthly, and gives you 50 deck generations, 100 image occlusions, 100 pages and 200,000 characters per document.

Ultimate costs $12 a month billed yearly at $144, or $20 monthly, and raises the limits to 200 deck generations and 1,000 image occlusions.

Page and character limits match Pro, so the upgrade only pays off if you generate a lot of decks.
