How does Crossleaf keep names and pronouns consistent?
It remembers. As a book translates, Crossleaf keeps its own list of the names in it and how each one is spelled, and holds every later chapter to it. Pronouns work the same way.
Long books drift when every chapter is translated on its own: the hero is Ji-hun in chapter one and Jihoon in chapter nine, and a heroine spends a chapter as he because the original never says. Crossleaf is built so that does not happen.
Names. As a chapter translates, Crossleaf notices every name that appears and the way it was rendered, and adds it to the book's glossary, marked kept by the book. From then on every chapter uses that rendering. The first spelling wins; if it is not the one you would have chosen, change it once in the glossary and Crossleaf offers to rename it across the whole book, free.
Pronouns. Korean, Japanese and Chinese often leave out who is doing what. Crossleaf notes she, he or they for a character as soon as the story makes it plain, keeps it, and holds every later chapter to it. Where the story has not said, nothing is assumed. You can set or change a character's pronouns yourself with the picker beside their name in the glossary.
What you have to do. Nothing, for most books. Open the glossary when a name or a pronoun looks wrong, fix it there, and retranslate or retry the chapters that came before the fix. Everything after it follows automatically.
For the full picture, see the guide Keeping names and terms consistent with the glossary. If a character already came out with the wrong pronouns, see A character has the wrong pronouns. How do I fix it?.
