Fields

Each Anki card generated by Tango has ten fields.

2nd Example Sentence Second example from the dictionary if available

Source Which API provided the definition

Card type

Tango generates recognition cards only. The front shows the word. The back shows everything else.

This is intentional. Production cards (seeing a definition and recalling the word) would make sense but would multiply the card count per word and bloat decks unnecessarily. Production practice can be added manually for words the user wants to study more deeply.

Fallback cards

When no definition is found in any API source, Tango creates a minimal card with just the word on the front and the transcript sentence as the only example. The Definition field shows "No definition found". These cards still appear in your deck so you do not lose rare or informal vocabulary.

Anki model ID

The genanki model ID is 1607392321. This number is baked into the .apkg file and tells Anki which card template to use. Do not change it manually. Changing it would cause Anki to treat all existing Tango cards as belonging to a different template, breaking their review history.

Dark mode compatibility

The card template uses Anki CSS variables like var(--fg) and var(--canvas) rather than hardcoded colours. This means cards automatically adapt to whatever theme the user has set in Anki, including dark mode.
