What is a deck?
How 2anki turns a Notion page or database into an Anki deck, and how to change which blocks create one.
A deck is a bag of flashcards in Anki. Every card you study lives in exactly one deck. When 2anki reads a Notion page, it has to decide where one deck ends and the next one begins — that's a deck boundary.
Plan: Free
The default rule
By default, two Notion block types create a deck boundary:
- page — every Notion page is its own deck.
- database — every Notion database is its own deck.
So if you point 2anki at a page called Pharmacology that contains a sub-page Antibiotics, you'll get a deck named Pharmacology and a sub-deck named Antibiotics. Cards under each heading or toggle end up in the matching deck.
On the free plan, 2anki reads the first 200 blocks of a page. Longer pages convert partially, and the deck's row on Downloads says how many blocks were converted. Paid plans convert the whole page.
Change which blocks create a deck
Rules apply to one Notion page at a time. To change the deck boundaries:
- Go to 2anki.net/notion and find the page.
- Click the Settings (gear) icon next to it.
- Under Decks and sub-decks → Deck boundaries, toggle the block types.
The supported boundary types are page and database. Pick at least one — if you deselect both, 2anki uses the default to avoid an empty deck.
| Selection | What you get |
|---|---|
page + database (default) | Pages and databases each become a deck |
page only | Only pages become decks; databases get inlined into the parent deck |
database only | Only databases become decks; child pages get inlined |
Sub-decks vs deck boundaries
A deck boundary starts a brand-new top-level deck. A sub-deck nests inside an existing deck. They're separate settings on the same page.
If you want a Notion sub-page to become a sub-deck instead of a separate top-level deck, leave page selected as a deck boundary and add child_page (or whichever block) to Sub-decks below.
See Parser rules for the full breakdown of every rule group, and Notion blocks we support for what each block does on the card itself.
