Start with the core concepts to see how your cards and study setup fit together. The remaining sections explain terms you may encounter while studying or changing settings.
Core concepts
Card
A card is one study item made from the fields in its deck's template. For example, a vocabulary card might show apple on the front and a fruit on the back. Cards can also contain images, recordings, language annotations, and other content.
Field
A field is one named part of a card, such as Term or Meaning. Its type determines the content it supports, such as text, an image, or audio. Its side determines where it appears; the name alone does not decide this. A field can be placed on Both sides, Front only, Back only, or Note. Note content lives in the note section, which is available on the back side only. On the example card, the Term field contains apple.
See Field types and Field settings and card sides.
Template
A template defines the structure shared by a deck's cards: field names, types, order, sides, and default settings. A deck has one template, and every card in that deck follows it. A vocabulary template might place a Text field named Term on Front and a Text field named Meaning on Back. The template defines those fields; each card supplies its own words. A card does not have to fill every field; you can leave some field values empty.
Changing the deck's template can affect every card in that deck. Deleting a field removes that field and its stored values from every card in the deck. Use that when you want to drop the same unused text or values across the deck in one change. See Templates and presets.
Deck
A deck is a collection of cards sharing a template. An Everyday vocabulary deck could contain cards for apple, water, and bread. Decks live in Home and hold the content used by both practice and SRS.
See Decks and folders.
Tag
A tag is a label attached to a card for organization and filtering. You could tag the apple and bread cards with food, then use that same tag on relevant cards in other decks. Tags group cards without moving them out of their decks.
Preset
A preset is a saved configuration you can reuse for deck templates, SRS settings, search filters, or AI instructions. It does not contain your studied cards or review progress. Presets are useful when you want the same setup again without rebuilding it each time: a familiar card layout for new decks, the same search filters, copied SRS settings, or consistent AI instructions. For example, a Simple vocabulary Deck Preset could save the Term-and-Meaning structure for creating more decks.
A new deck receives its own template from a Deck Preset. Applying an SRS Preset also copies settings into the set. AI instruction presets work differently: a deck keeps its selection, and editing that preset changes the instructions used for future generation requests, without rewriting existing results or cards.
See Presets and AI instruction presets.
Set (SRS set)
An SRS set links one or more decks for scheduled study using the set's review settings. A Daily vocabulary set could link Everyday vocabulary and Travel phrases. Each card has its own schedule, and the set uses the cards already in Home; it does not create another editable copy.
A deck can belong to only one SRS set at a time. See Start spaced repetition.
Folder
A folder organizes other items. In Home, an English folder could contain your vocabulary decks and subfolders. In SRS, a separate Language practice folder could contain your SRS sets and subfolders. Home folders and SRS folders are separate structures.
