The library: classes, courses, and book decks

Encodr's library isn't just flashcards attached to your own notes - there's a whole shelf of curated content you can open and start studying without building a single card. It splits into three rough kinds.

Curated exam and subject classes

These are the deep, structured decks built for a specific body of knowledge someone's actually being tested on - the Ultimate MCAT Deck (6,900 cards, 6 units matching the AAMC's own breakdown) and the Texas General Lines P&C licensing deck (801 cards across 15 units) are the two biggest examples. Classes like this are organized in units and chapters that mirror how the actual exam or course is structured, not an arbitrary alphabetical split.

Standalone courses

A newer, lighter shelf: focused single-topic decks like world history and etymology, each built as 4 units / 12 chapters with a consistent card mix per chapter rather than the exam-scale depth of a class like MCAT. These are for topics you're curious about rather than being tested on - shorter, self-contained, and meant to be finished rather than maintained indefinitely.

Book decks

Full books turned into study decks - Meditations, the Art of War, the Republic, and others - one idea per card, organized to follow the book's own structure. These sit in the Library's genre shelves and get recommended based on what you've actually read and finished, not just what you said you were interested in during onboarding; see how Encodr picks your first deck for how that recommendation logic actually weighs your behavior over your stated preferences.

Curated doesn't mean fixed

Every curated deck goes through the same sourcing and citation process as a class you'd build yourself - see where your cards' facts come from - and gets refined over time as gaps or errors surface. The difference from building your own deck isn't quality, it's who did the work of researching and structuring it before you opened the app; curated classes vs. building your own deck covers that trade-off directly if you're deciding between the two for something you're studying right now.
