## Formatting a finished book

Atticus is a strong formatting tool for authors who have finished writing. You import your manuscript, choose a template and fonts, check the previews, and export EPUB, PDF or DOCX. Because it runs on every major platform, it is the common Vellum alternative for authors on Windows.

BuildPDFs can format a finished manuscript too. Paste your text, pick a book design and you get a print-ready 6×9 or 5.5×8.5 interior with front matter, chapter openers, drop caps, mirrored margins, running heads and page numbers that start at chapter one.

## Writing and designing, not only formatting

The difference is the AI. In BuildPDFs you can start from an outline or rough notes, and the AI helps you write and structure the chapters. You change the format the same way, by asking. This is useful for nonfiction authors, coaches and experts who want a book quickly and also need related material: a lead magnet from chapter one, a companion workbook or a one-page media kit.

Formatting changes work the same way. Ask for a larger body font, a different chapter opener or a new section in the front matter, and the whole interior updates with the page numbers and table of contents still correct.

## Which to use

If you have a finished manuscript and want EPUB and print files from one desktop-style app, Atticus does that well for a one-time price. If you want AI to help write, design and format your book interior, plus the documents that promote it, BuildPDFs does all of that in one conversation.
