Frequently asked questions
What heading formats are supported?
Lines starting with "Chapter" or "CHAPTER" plus a number or Roman numeral, with optional titles after.
Can I keep chapter subtitles?
The formatter preserves subtitle text after the number when present in the source heading.
Does it work on AI-exported manuscripts?
Yes. AI exports often mix CHAPTER 1 and Chapter 1 styles — this unifies them.
