Summarize YouTube videos & chat about content with GPT-4o-mini via Telegram

Summarize YouTube Videos & Chat About Content with GPT-4o-mini via Telegram Description This n8n workflow automates the process of summarizing YouTube video transcripts and enables users to interact with the content through AI-powered question answering via Telegram. It leverages the GPT-4o-mini model to generate summaries and provide insights based on the video’s transcript. How It Works 1. Input: The workflow starts by receiving a YouTube video URL. This can be submitted through: - A Telegram chat message. - A webhook (e.g., triggered by a shortcut on Apple devices). 2. Transcript Extraction: The URL is processed to extract the video transcript using the custom youtubeTranscripter community node (available here). The transcript is concatenated into a single text and stored in a Google Docs document. 3. Summarization: The GPT-4o-mini AI model analyzes the transcript and generates a structured summary, including: - A general overview. - Key moments. - Instructions (if applicable). The summary is then sent back to the user via Telegram. 4. Interactive Q&A: Users can ask questions about the video content via Telegram. The AI retrieves the stored transcript from Google Docs and provides accurate, context-based answers, which are sent back through Telegram. Setup Instructions To configure this workflow, follow these steps: 1. Import the Workflow: Download the provided JSON template and import it into your n8n instance. 2. Install the Community Node: Install the youtubeTranscripter community node via npm: Important: This node requires a self-hosted n8n instance due to its external dependencies. 3. Configure Nodes: - Webhook: Set up the webhook to receive YouTube URLs. Alternatively, configure the Telegram node if using Telegram as the input method. - Google Docs: Provide valid credentials to enable writing the transcript to a Google Docs document. - AI Model: Set up the GPT-4o-mini model for summarization and Q&A functionality. 4. Test the Workflow: Send a YouTube URL via your chosen input method (Telegram or webhook) and confirm that the summary is generated and delivered correctly. Customization - Language: Adjust the AI prompts to generate summaries and answers in any desired language. - Output Format: Modify the summary structure by editing the prompt in the summarization node. - Input Methods: Replace the Telegram node with another messaging or input node to adapt the workflow to different platforms.
