YouTube chapters with timestamps

Write one section per line in the format «Title | duration» (e.g. «Intro | 0:45»): get ready chapters with cumulative timestamps.

What it's for

YouTube creates automatic chapters if your description has a list of timestamps starting at 0:00. This tool computes them for you from each section's length.

How it works

Write the title, a vertical bar «|» and that section's duration (mm:ss). The first chapter always starts at 0:00, as YouTube requires.
