Frequently Asked Questions
How does the auto-detect mode work?
The tool scans your script for transition phrases like "next", "let's talk about", "moving on to", and "finally". It extracts the sentence following each phrase and assigns proportionate timestamps.
Can I edit the chapter titles after generation?
Yes. Each chapter title appears in an editable text field. Click and type to customize before copying.
How are timestamps calculated?
The total video length is divided evenly among the selected or detected sections. For example, a 10-minute video with 5 sections gets 2-minute segments.
What is the maximum number of chapters?
YouTube supports up to 15 chapters per video. The auto-detect mode caps at 15 sections, and the manual mode allows up to 8 preselected sections.
Is this tool free?
Yes, completely free. No sign-up, no API calls, no data leaves your browser. All processing happens locally.
Two Generation Modes

What Is a YouTube Chapter Generator?

Why YouTube Chapters Matter for SEO
Chapters improve viewer experience by letting users jump to specific parts of your video. They also help YouTube understand your content structure, which can improve search rankings and increase watch time.
Best Practices for YouTube Chapters
Keep chapter titles concise and descriptive (under 60 characters). Use keywords naturally. The first chapter should start at 0:00. Ensure each chapter is at least 10 seconds long for YouTube to display them.
