Free YouTube Chapter Generator – Instant Timestamps, Description & Pinned Comment

YouTube chapters are free SEO that most creators ignore. When you add timestamps to your video, YouTube shows your chapters as “Key Moments” in Google search results — giving your video extra real estate on the search page and making it easier for viewers to navigate to the exact part they want. Our free ChapterAura tool generates professional chapters, an SEO-optimized description, relevant hashtags and a ready-to-pin comment — all from your transcript in seconds.

Simply paste your video transcript or auto-generated captions from YouTube Studio, enter your video title and target keyword, and ChapterAura will analyze the structure of your content and generate accurate chapter timestamps with clean labels. You also get a full video description with the first 150 characters optimized for the above-the-fold snippet — the most important real estate in your description that appears in search results before the “Show more” button.

According to YouTube’s official support documentation, adding chapters improves viewer experience and can increase watch time by helping viewers find the most relevant section of your video. Combined with an optimized description, chapters are one of the highest-ROI SEO actions a creator can take on any existing video.

ChapterAura is part of the free WebifyAura YouTube tools suite. After generating your chapters, optimize your thumbnail with ThumbAura, perfect your title with TitleAura, and write a powerful hook with HookAura.
