How do I add chapters to a YouTube video?+
Paste a list of timestamps and titles into your video's description, starting with 0:00. YouTube automatically turns them into clickable chapters. This tool builds and validates that list for you.
What are YouTube's rules for chapters?+
The first timestamp must be 0:00, you need at least three chapters, they must be in ascending order, and each chapter must be at least 10 seconds long. The tool warns you if any rule is broken.
What timestamp format should I use?+
Use mm:ss for videos under an hour (e.g. 4:35) or hh:mm:ss for longer ones (e.g. 1:04:35). Either works here.
Is this free?+
