Youtube Video Summariser using n8n and AI

How it works

• Starts when a user sends a chat message with a YouTube link or question.
• Extracts video ID, type of request (new video, context, or follow-up).
• Fetches video transcript and detects language.
• Translates non-English (e.g., Hindi) into English.
• Saves transcript and context for future questions.
• Uses AI to answer questions or summarize based on transcript.
• Updates a connected Google Doc with processed transcript or responses.
• Maintains conversation history for continuity.
