Already wrote something elsewhere? You don't have to start from scratch or copy and paste chapter by chapter. Writer Mode can ingest a finished document and turn it into a properly structured, editable manuscript in seconds — splitting it into chapters automatically along the way.

Supported file types

You can upload any of these directly into the editor:

• .txt — plain text
• .md — Markdown
• .docx — Microsoft Word
• .pdf — PDF documents
• .epub — EPUB ebooks
• .mobi — Kindle/MOBI files

How to import

1. In the editor, choose Import / Upload manuscript.
2. Select your file from your computer.
3. BookZeta parses your headings into separate chapters automatically — when it sees patterns like "Chapter One" or "Chapter 2", it creates a new chapter at each break.
4. Review the split in the chapter list, then rename or merge chapters as needed.

Once imported, everything is fully editable: you can rewrite by hand, reorder chapters, or polish passages with the AI assistant.

Tips for a clean import

• Use consistent heading styles. If every chapter starts with the same recognisable label (e.g. "Chapter One", "Chapter Two"), the auto-split detects breaks reliably. Inconsistent or missing headings may leave everything in one long chapter.
• Give large PDFs a moment. Very large or image-heavy PDFs take a little longer to process — let it finish before editing.
• Check the chapter list first. After import, scan the sidebar. If the split isn't quite right, use chapter management to add, reorder, rename or delete chapters until the structure matches your book.

After you import

• Edit everything by hand, or lean on the AI assistant to rewrite, expand, shorten or change tone.
• Cast your cast: pull characters and settings in from your Series Bible so the editor and AI know who's who.
• When the structure is settled, you can rebuild your table of contents and head toward export.

Common pitfalls

• Everything landed in one chapter. Your source file probably didn't use detectable headings. Split it manually in the chapter list, or re-export the original with clear "Chapter" headings and try again.
• Formatting looks slightly different. Importers carry across structure and text faithfully, but very custom styling from another tool may simplify. Tidy anything that matters with the toolbar after import.
