YouTube Transcript, Summary, AI Chatbot - SubKun

Get clean YouTube transcripts, AI summaries, and chat with any video. Smart segmentation makes them readable, not raw captions.

You can't skim a video. You can't ask a video a question. And you can't tell whether an hour-long lecture is worth your time until you've already spent it. SubKun fixes all three. It reads any YouTube video right alongside it — the full talk as clean, readable text, a quick summary before you commit, and an AI that answers your questions about what you're watching. Stop rewinding and re-listening. Start reading, skimming, and asking. WHAT YOU GET • Read, don't watch — The whole video written out beside it, cleanly re-segmented into natural sentences. Read at your own pace, skim what you already know, slow down on what matters. • A summary up front — Know what a video actually covers, and whether it's worth your hour, before you press play. Click any point to jump straight to that moment. • Ask AI anything — Lost in a lecture? Just ask, and get an answer about this specific video. And when you don't know what to ask, SubKun hands you the exact questions a sharp student would — click one and go deeper. • Find your place instantly — Search the transcript or click any line to jump to that exact second. No more scrubbing the timeline to find where you drifted off. • Works on almost any video — Open it and the transcript appears in real time. No captions on the video?
