Copyright tags name a series. They pull in the series' palette, outfit lineage and overall look rather than one character, and keep same-name characters from being confused. 500 tags are listed for V4.5.
Cards show the series' top character so the look is recognizable; open one to browse the characters that belong to it.
Place the copyright tag right after the character tag: "rem (re:zero), re:zero kara hajimeru isekai seikatsu, 1girl, solo".
Top-scoring series tags; cards show the top character.
V5 reacts more readily to recent series; V4.5 carries more detail for classic and doujin-heavy series.
What happens with only a copyright tag?
You get a representative character or outfit of that series. Put a character tag first to target one.
Are the card images official art?
No. They are NovelAI samples generated from the top character's tag.
Pick a series to see its character tags with sample images. Series with the most characters come first.
