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 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. 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. ● Full Video Transcript in Seconds — Get a complete, timestamped transcript of any YouTube video—even when no captions exist. Our AI listens to the audio directly and generates accurate bilingual transcripts in under 6 seconds. No more pausing, rewinding, or guessing. ● Instant AI Summary — Don't have 40 minutes? Get the key points in 40 seconds. SubKun condenses long videos into clean, structured summaries so you can decide what's worth watching—or skip straight to the takeaways. ● Ask AI About Any Video — Chat with the video like it's a document. Ask "What did the speaker say about X?" or "Give me the three main arguments" and get instant, context-aware answers grounded in the actual content. ● Click-to-Jump Navigation — The sidebar shows the full bilingual transcript in real time. Click any line to jump straight to that moment in the video—perfect for research, reviews, and pulling reference clips. ● AI-Powered Bilingual Subtitles — Beyond word-for-word translation. Our engine reconstructs sentences based on full context for subtitles that read naturally, not robotically. ● Smart English Subtitles — Re-Punctuated for Reading — YouTube's auto-captions break sentences mid-thought and skip punctuation entirely. SubKun's AI re-segments captions into clean, complete sentences with accurate punctuation, so the English script reads like real writing—perfect for note-taking, study, and pulling quotes. ● Word-by-Word Highlight Sync — Subtitles light up word by word, in time with the speaker—so it's easy to follow along with dense or fast-paced content, even at higher playback speeds. ● Fully Customizable Subtitle Styling — Adjust fonts, colors, backgrounds, and stroke effects so subtitles look clean and stay out of the way. ● High-Accuracy Speech Recognition — Handles diverse English accents and technical jargon with exceptional accuracy, as long as the source audio is reasonably clear. ● Inline Word Lookup — Hover or click any word in the transcript for an instant translation, complete with natural-sounding pronunciation powered by Microsoft's AI voice engine. ● Free Daily Quota — Generous free credits reset every day—plenty for everyday viewing, research, and summarizing.
