The words Lectro uses
| Term | What it is |
|---|---|
| Skill tree | A subject, drawn as a map of topics. |
| Node | One topic on the map. It holds notes and opens once the nodes it builds on are learned. |
| Note | What you write down: a question and answer, a cloze, anything with fields. A note can sit in many nodes, or none. |
| Notetype | The fields a note has and the templates that turn it into cards. Basic, Basic (and reversed) and Cloze come with every account. |
| Card | One thing you are asked. A note makes one card or several. |
| Source | A book, page or video a note cites, down to the chapter or timestamp. |
| Session | A set of cards seated when you start, so the session you start is the one you finish. |
| Protocol | The scheduler that decides when a card is due (FSRS by default). Every revision is kept. |
