Video Summary

Video Summary is useful when you want to quickly pick out the key points from courses, interviews, podcasts, tech talks, and long videos. Based on the subtitles available for the current video, it automatically generates a summary and several key takeaways, along with clickable timestamps so you can jump back while watching.

Where to Open It

Open the plugin’s D panel on a supported video page, then switch to the Summary tab.

If the current page has already recognized the video and subtitles successfully, click Generate Summary to start processing.

How It Works

1. Open the video page and make sure the current video has subtitles available.
2. Click the D entry next to the player or somewhere on the page to open the right-side panel.
3. Switch to Summary.
4. Click Generate Summary.
5. Wait a few seconds, and the panel will show the summary and highlight outline.

What You Will See

After generation is complete, the page usually shows two parts:

1. Summary A shorter description of the video’s main idea, useful when you want to quickly decide whether the video is worth watching.
2. Highlights Key points grouped by topic, each with timestamps. Clicking a timestamp will jump directly to that point in the video.

If the video is long, the system will generate more highlights automatically. If the video is short, the result will be simpler.

Copy and Review

After the summary is generated, you can:

1. Click Copy in the top-right corner of the summary card to copy only the summary text.
2. Click the Copy button at the bottom to copy the full summary and highlight outline.
3. Click any timestamp to jump back to that part of the video and watch it again.

Output Language

The output language for Video Summary follows the target language setting in your plugin.

For example, if you usually set the plugin target language to Chinese, the generated summary will usually also be in Chinese. If you switch to English, Japanese, or another target language, the summary will try to follow that language as well.

Limitations

1. Summary is currently a member-only feature, and non-members will see a message saying it is unavailable.
2. If the current video has no subtitles available, the summary cannot be generated.
3. Summary quality depends on subtitle quality. The more complete and accurate the subtitles are, the more stable the result usually is.
4. This feature depends on the plugin successfully recognizing the current video context, so it only works on supported video sites and pages.

Good Use Cases

1. Quickly review the main points of a course before class.
2. Extract the key themes from long podcasts, interviews, or meeting recordings.
3. Jump back to important moments in a video you have already started watching.
4. Generate a summary first when you want to decide whether a long video is worth a deeper watch.
