YouTube Chapter Builder — Complete Guide

Creating timestamps for YouTube videos can be a tedious process. The YouTube Chapter Builder simplifies this by allowing you to watch your video and insert the exact timestamp into your text simply by pressing a hotkey. No more switching tabs or pausing to write down the time.

How to Use

  1. Load Video: Paste your YouTube URL in the input box and click "Load".
  2. Start Playing: Play the video in the embedded player.
  3. Insert Timestamp: Whenever the topic changes, press Alt + Space on your keyboard (or click the "Insert Time" button). The current time (e.g., 03:45) will appear in the text editor.
  4. Add Titles: Type the title of the chapter right next to the inserted timestamp (e.g., 03:45 Main Topic).
  5. Copy & Paste: Click "Copy Chapters" and paste the text directly into your YouTube video description!

Important YouTube Guidelines

For chapters to work on YouTube, you MUST follow these rules:

  • The first timestamp must start at 00:00.
  • You need at least 3 timestamps.
  • Each chapter must be at least 10 seconds long.

Frequently Asked Questions

What advantages does this have over video editing software?

Usually, chapters are added to the description after the final video rendering. Opening heavy editing software like Premiere Pro just to note down times is inefficient. This tool runs instantly in your browser and lets whoever manages the channel's uploads quickly create the timeline.

Is my video data uploaded anywhere?

No. This tool uses the official YouTube IFrame Player API. Everything happens entirely in your browser (client-side). We do not track, save, or store the videos you watch or the chapters you create.
