Users want to ask questions about video content without watching entire videos. Building a chatbot that understands video content requires reliable transcript extraction, intelligent chunking, and a conversational interface. Existing solutions are fragile and break when YouTube changes their page structure.
YouTubeTranscripts.co gives you a stable, production-grade API for extracting video transcripts. Feed the transcript into GPT-4, Claude, or any LLM to create conversational interfaces. Users can ask specific questions and get answers with timestamps linking back to the original video.
