Frequently asked questions

Is the YouTube Timestamp Generator free?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.

When would I actually need the YouTube Timestamp Generator?
The jobs it is built for: adding chapters so viewers can jump to sections. Fixing chapters YouTube refused to display. Converting notes taken while editing into a chapter list. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
