Prompt
Create chapters from a supplied timestamped transcript. Input: use only the notes at the end. If a fact this job needs is missing, ask one direct question and do not guess. Format for YouTube chapter timestamps: 1. Use actual start times and distinct topic labels. 2. Do not invent timing when the transcript has none. Do not add facts, names, dates, numbers or sources that are not in the notes. Notes: Transcript times from a clock-repair talk. A later goodbye has no timestamp, so it is not given a minute. 0:00 case open on the bench. 1:05 why the spring was stuck. 3:40 what the 1912 mark on the plate shows. 6:10 oiling points the maker allows. 7:55 what this talk does not settle. The spring problem and the 1912 mark stay separate because the transcript changes topic at 3:40.
Customise
Paste the list, names, dates or other facts this prompt should use.
Fields start with illustrative values; replace them with your own facts. The prompt updates as you type. Copy prompt copies your version.
