Free local publishing check
Make every chapter
easy to find.
Paste your own YouTube chapter draft, check the published timestamp basics, then copy one clean block for your video description.
Your chapter draft
Accepted timestamps: m:ss or h:mm:ss. Blank lines are ignored; titles stay exactly as you wrote them except for surrounding spaces.
A preflight check, not a publisher
Use the final list you actually want viewers to see.
YouTube's current help says manual chapters start at 0:00, have at least three timestamps in ascending order, and are at least 10 seconds long. Add your own titles and review the finished list alongside the actual edit.
This tool formats and checks pasted text only. It does not inspect or upload a video, generate titles, transcribe audio, access YouTube Studio, determine feature eligibility, override automatic chapters, or guarantee that chapters will appear.
