YouTube's chapter rules
The first timestamp must be 00:00.
At least three timestamps, in ascending order.
Each chapter must be at least 10 seconds long.
If any rule fails, YouTube ignores the whole list. This tool checks all three, fixes formatting (0:45 → 00:45), sorts the lines and accepts "Title - 1:30" or "[01:30] Title" styles.
Frequently asked questions
Where do I paste the chapters?
In the video description, on their own lines.
Why don't my chapters show?
Usually the first timestamp isn't 00:00, there are fewer than three, or a chapter is under 10 seconds. The checker flags each of these.
Do chapters help SEO?
Chapters can appear in Google search results as 'key moments' and make long videos easier to navigate.
