How to check your chapters
Chapter lists go wrong in predictable ways: a timestamp out of order, a missing hour marker, a first chapter that does not start at 0:00, or a title that is too long. The Chapter Checker looks for these problems.
It runs in your browser, and nothing you paste is sent to a server.
- Paste your chapter list, one chapter per line, for example 0:00 Introduction.
- Read the notes the checker gives you, and fix any problems it finds.
- Copy the corrected list into your video description.
What the checker looks at
Timestamps should be in order and use the same format throughout. The first chapter should start at 0:00. Titles should be short and easy to scan.
