YouTube Description Generator

YouTube Description Generator assembles a description out of the parts you type — title, summary, chapter list, links and hashtags — and checks the chapter timings against the rules the code holds for them.

Each chapter line is read as mm:ss or hh:mm:ss followed by a label, and the list is re-sorted by time, so lines entered out of order come back in order. Three checks then run: fewer than three chapters, a first chapter that does not start at zero, and any two chapters less than ten seconds apart each raise a warning instead of being quietly accepted. Hashtags past the fifteenth are dropped from the output, and the first 157 characters are shown separately because that is the slice that sits above the fold. It formats what you write and invents nothing — there is no suggestion engine behind these fields.

The description is built from the form fields in the page and handed back as text and a .txt file. Nothing you type is transmitted, and no video or channel is read.

Writing a description whose chapters will actually register, reusing one link block across every upload, checking what shows before the fold, and catching a mistyped timestamp before it costs you the chapter bar.
