What makes it work
Chapters from 0:00
YouTube builds chapters when the list starts at 0:00, has at least three timestamps and each chapter lasts 10 seconds or more.
Hashtags at the end, 3 of them show

Questions
How long can a YouTube description be?
Up to 5,000 characters. The first 100–150 show before “more”, so the important part goes first and the details below.
Does the description help my video rank?
It tells YouTube and viewers what the video is about. A clear first paragraph with the search phrase helps; stuffing keywords does not.
Can it write timestamps for my video?
The AI does not watch the video. List the parts in your brief and it writes the chapter titles; you add the exact times.
Does it work for Shorts?
Yes. Choose a short variant: for Shorts one or two lines and a couple of hashtags are enough.
Can AI SMM upload videos to YouTube?
Yes, one video per post with title and description on schedule; comments come into the inbox and statistics into analytics.
