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.

SubKun — AI YouTube Transcript, Summary, Subtitles & Ask AI SubKun turns any YouTube video into readable subtitles, a searchable transcript, a clear summary, and an AI you can chat with. Get the gist in seconds, find the exact moment that matters, and ask questions about anything you just watched—all without leaving the page. Why SubKun? Most YouTube tools stop at line-by-line translation. When a sentence gets split across two caption lines, the output falls apart—broken phrases, missing context, no real meaning. SubKun goes further. Our AI reads the full context of each sentence, stitches fragmented segments back together, and produces subtitles, transcripts, and translations that actually make sense. The result reads the way humans write—perfect for skimming long videos, pulling quotes, or summarizing tech reviews, TED Talks, podcasts, and tutorials in seconds.
