Open Styles under Settings. You can create a style from pasted text or from a PDF, DOC, DOCX, or TXT file.

Give the style a name and provide a representative sample. Books analyzes the sample into guidance used during eligible generation. Longer, consistent samples usually produce more useful guidance than a mixture of unrelated voices.

You can edit a custom style, make one the default, or delete it. The default is preselected for new work; changing it does not rewrite existing books.

Review the writing options in a brief before generation if a specific book needs a different style, point of view, tense, or tone.
