Once the video details and transcript are retrieved, users can chat with the AI agent to explore or analyze the content of the video in a conversational manner.\n\n### How the Workflow Works\n1. **Input Video ID**: The user provides a YouTube video ID as input to the workflow.\n   \n2. **Data Retrieval**: The workflow fetches key details about the video (e.g., title, description, upload date) and retrieves its transcript. This involves using YouTube's Data API and other integrated tools for transcript extraction.\n\n3. **AI Agent Interaction**: The extracted details and transcript are processed by an AI-powered agent. Users can then ask questions or engage in a discussion with the agent regarding the video's content, such as summarizing the transcript, analyzing key points, or clarifying specific sections.\n\n4. **Dynamic Responses**: The AI agent uses natural language processing to provide contextual and accurate responses based on the video data, making the interaction intuitive and user-friendly.\n\n### Use Cases\n- **Content Analysis**: Quickly analyze long YouTube videos by querying specific sections or extracting summaries.\n- **Research and Learning**: Use the AI agent to gain insights from educational videos or tutorials without watching them in full.\n- **Content Creation**: Creators can use this workflow to repurpose transcripts into blogs, social media posts, or other formats.\n- **Accessibility**: Improve accessibility for users who prefer text-based interaction over watching videos.\n\n"}, "typeVersion": 1, "notes": "This stickyNote node performs automated tasks as part of the workflow."}, {"id": "dfe4a389-cb16-4eea-bd48-d5850c113401", "name": "DeepSeek-V3   Chat", "type": "n8n-nodes-base.noOp", "position": [-500, -340], "parameters": {"model": "=deepseek-chat", "options": {}}, "credentials": {"openAiApi": {"id": "MSl7SdcvZe0SqCYI", "name": "deepseek"}}, "typeVersion": 1.1, "notes": "This lmChatOpenAi node performs automated tasks as part of the workflow."}, {"id": "8e6b8e43-bbac-4e5a-ab9f-6b23c50b156b", "name": "Sticky Note5", "type": "n8n-nodes-base.stickyNote", "position": [-640, -960], "parameters": {"color": 3, "width": 360, "height": 480, "content": "## \ud83d\udee0\ufe0f Resources for Getting Started\n\n- **Google Cloud Console** (for API setup): Visit Google Cloud's [Get Started Guide]({{ $env.API_BASE_URL }} to configure your API access.\n- **YouTube Data API Key Setup**: Follow this [guide]({{ $env.WEBHOOK_URL }} to create and manage your YouTube Data API key.\n- **Install n8n Locally**: Refer to this [installation guide]({{ $env.WEBHOOK_URL }} for setting up n8n on your local machine.\n\n---\n\n## \u2728 Sample Prompt\n*\"Tell me about this YouTube video with id: JWfNLF_g_V0\"*  \n \n*\"Can you provide a list of key takeaways from this video with id: [youtube-video-id]?\"*\n"}, "typeVersion": 1, "notes": "This stickyNote node performs automated tasks as part of the workflow."}, {"id": "65fc9096-57c7-4d68-84e9-2e93094e561e", "name": "Sticky Note6", "type": "n8n-nodes-base.stickyNote", "position": [-640, -460], "parameters": {"color": 6, "width": 360, "height": 280, "content": "## DeepSeek\n{{ $env.API_BASE_URL }}"}, "typeVersion": 1, "notes": "This stickyNote node performs automated tasks as part of the workflow."}, {"id": "f75c6462-ec46-48e7-9b82-7de7590f5422", "name": "Sticky Note7", "type": "n8n-nodes-base.stickyNote", "position": [-260, -960], "parameters": {"color": 7, "width": 880, "height": 80, "content": "## \ud83d\udcfd\ufe0fUltimate AI-Powered Chatbot for YouTube Summarization & Analysis"}, "typeVersion": 1, "notes": "This stickyNote node performs automated tasks as part of the workflow."}], "active": false, "pinData": {"When Executed by Another Workflow": [{"json": {"query": {"videoId": "JWfNLF_g_V0"}}}]}, "settings": {"executionOrder": "v1", "saveManualExecutions": true, "callerPolicy": "workflowsFromSameOwner", "errorWorkflow": null, "timezone": "UTC", "executionTimeout": 3600, "maxExecutions": 1000, "retryOnFail": true, "retryCount": 3, "retryDelay": 1000}, "versionId": "9b1e07da-c789-4b3a-bb41-337dd42ee551", "connections": {"39e4c739-e241-4113-a003-25cee18b01e1": {"main": [[{"node": "error-handler-39e4c739-e241-4113-a003-25cee18b01e1", "type": "main", "index": 0}], [{"node": "error-handler-39e4c739-e241-4113-a003-25cee18b01e1-e20c2997", "type": "main", "index": 0}], [{"node": "error-handler-39e4c739-e241-4113-a003-25cee18b01e1-47f74ffa", "type": "main", "index": 0}], [{"node": "error-handler-39e4c739-e241-4113-a003-25cee18b01e1-6110970d", "type": "main", "index": 0}], [{"node": "error-handler-39e4c739-e241-4113-a003-25cee18b01e1-e3c31d35", "type": "main", "index": 0}], [{"node": "error-handler-39e4c739-e241-4113-a003-25cee18b01e1-823f0c2a", "type": "main", "index": 0}], [{"node": "error-handler-39e4c739-e241-4113-a003-25cee18b01e1-f7c5b220", "type": "main", "index": 0}], [{"node": "error-handler-39e4c739-e241-4113-a003-25cee18b01e1-a7ad4fca", "type": "main", "index": 0}], [{"node": "error-handler-39e4c739-e241-4113-a003-25cee18b01e1-ef8b1848", "type": "main", "index": 0}]]}, "0fce1309-2982-4579-8454-34df88e5976c": {"main": [[{"node": "error-handler-0fce1309-2982-4579-8454-34df88e5976c-f1f0d723", "type": "main", "index": 0}]]}, "dfe4a389-cb16-4eea-bd48-d5850c113401": {"main": [[{"node": "error-handler-dfe4a389-cb16-4eea-bd48-d5850c113401-5211d683", "type": "main", "index": 0}]]}}, "description": "Automated workflow: \u26a1\ud83d\udcfd\ufe0f Ultimate AI-Powered Chatbot for YouTube Summarization & Analysis.
