Repair the manuscript you already have.
Find the structural problem, choose between repair and conversion, or investigate a publishing warning. Start with the file you have and the result you need.
Find your next check
Choose the file you have, then the symptom you can reproduce. This guide finder does not inspect or upload a file. It points to checks, not a diagnosis or a promise of repair.
Not sure which applies? Identify your source and intended result first. Keep the original file and inspect the actual export before publishing.
Browse all repair guides
Use the EPUB or DOCX guide for a source-file problem. Use the EPUBCheck guide to read a validation report, the footnote checklist to test a note and its return link, or the KDP checklist when a publishing warning needs diagnosis. If you are unsure whether the next step is repair, a new design or conversion, start with the workflow guide.

Diagnose broken EPUB contents links, missing navigation entries and heading levels. Review a repair in ChapterTidy, then check the exported file in your reader.

Read guideUse evidence from your own file
These guides explain the checks ChapterTidy can make and the review that remains yours. A structurally valid file can still display differently across readers. Open the actual export, test its navigation and inspect the text and images before publishing.
ChapterTidy uploads files to its server for processing. Files are retained for 24 hours by default and can be deleted in the workspace. The included sample lets you explore the workflow before uploading your own manuscript.
