Other tools give you PNG files and leave you to assemble the book yourself. Hours of manual work per book.
Manually converting images, numbering grids, creating palettes — it takes forever.
Other tools export PNGs. You still have to build the book yourself in Canva or InDesign.
Competitors output 2K resolution (~150 DPI). Not sharp enough for professional print.
Upload, wait, download, repeat. No bulk processing. No batch export.
No table of contents, no answer key, no title page, no copyright — you build it all.
No KDP compliance. You guess at margins and hope Amazon doesn’t reject your upload.
