InsightCut — YouTube summaries & key moments

Long videos pile up in Watch Later and never get watched. InsightCut pulls the key moments and summaries — right on YouTube.

No time for hour-long videos? You save them to Watch Later — and never come back. Install InsightCut and the demo opens on a 56-minute video where it found the 26 minutes that matter. Read the key insights first, then decide what to watch. On any YouTube video page, click ✨ Make insights to get part-by-part summaries and key moments. · Part summaries — know what a 60-minute video says in one scroll · Key moments — play only the segments that matter, skip the rest · 3-line insights — the key takeaways of the current moment, kept on screen while you watch · Subtitle translation — clean, readable subtitles built by our own algorithm (Korean, English, Japanese, Chinese, Spanish) InsightCut runs only on youtube.com and never reads other sites.
