Purpose
The rate at which I save YouTube videos is always faster than the rate at which I can actually watch them. Research videos I’ve bookmarked, videos I’ve saved for later, links I copied because they might become references—they keep piling up. The bottleneck is time.
Most existing YouTube summarization tools rely on embedded subtitles, i.e., transcripts uploaded by the creator. If a video has no transcript, summarization becomes impossible. Videos without Korean subtitles, videos with low-quality auto-captions, or videos with no captions at all still require watching from start to finish.
