"I spent more time formatting, uploading, and tweaking Amazon listings than I did writing the actual book."

Every indie author knows this grind. You write the book, then spend weeks on editing, cover design, formatting, metadata, uploading to KDP, running ads, managing reviews. The creative work is 20% of the job. The other 80% is production logistics. ChapterMill eliminates the 80%.
