Summarize an Article

1. Navigate to any article or blog post
2. Click the Speedrun icon in your toolbar
3. The extension extracts the article text and generates an audio summary

• Audio Summaries: Every summary includes a natural-sounding audio version you can listen to at 1x, 1.25x, 1.5x, or 2x speed.
• What Viewers Said: For YouTube videos, Speedrun highlights the most insightful comments so you can see what the community thinks.
• Time Comparison: See how long the original video or article takes compared to the summary, so you know exactly how much time you're saving.
• Share Links: Share any summary with a link. Recipients can read or listen without needing the extension installed.

What videos work with Speedrun?

Speedrun works with any YouTube video that has captions or subtitles available. This includes most videos, since YouTube auto-generates captions for the majority of content.

Why does it say "no captions available"?

Some videos have captions disabled by the creator, or the video may be too new for YouTube to have generated automatic captions. Try again later, or check if the video has subtitles enabled.

How does audio playback work?

Speedrun generates a natural-sounding audio version of each summary using AI text-to-speech. You can play, pause, scrub through the timeline, and adjust playback speed. Audio streams directly — no downloads required.

What data does Speedrun collect?

Speedrun only processes publicly available video metadata, transcripts, and comments when you click the Speedrun button. We don't collect personal information, browsing history, or account credentials. See our Privacy Policy for full details.

What sites are supported?
