AI YouTube Video Summarizer Agent

Unlock Efficient Content Consumption with this AI Agent

This powerful AI Agent automates the summarization of YouTube videos. It intelligently extracts transcripts from provided YouTube URLs using a configurable HTTP request (e.g., to Apify or a similar service) and then employs Langchain with OpenAI's advanced language models to generate clear, concise summaries. Stop spending hours on long videos; get the key takeaways in minutes.

Key Features & Benefits

• AI-Powered Summarization: Leverages Langchain and OpenAI's LLMs (e.g., GPT-3.5-turbo, GPT-4) for accurate and human-like text summaries.
• Flexible Transcript Source: Uses an HTTP Request node to fetch transcripts, easily configurable for services like Apify or your custom solution.
• Simple Input: Starts with a user-friendly form to input the YouTube video URL.
• Time-Saving Automation: Drastically reduces the time needed to digest video content.
• Actionable Insights: Transforms lengthy videos into actionable summaries, ideal for research, content repurposing, or staying informed.
• Customizable Trigger: While it starts with a form, it can be adapted to trigger via webhook or other n8n triggers for broader integration.

• An n8n instance (Cloud or self-hosted).
• OpenAI API Key with access to a suitable model (e.g., gpt-3.5-turbo or gpt-4).
• API credentials for a YouTube transcript service (e.g., Apify). The HTTP Request node is pre-configured for an Apify-like structure but requires your specific Apify Actor run URL (including API key and POST endpoint).

1. Download the n8n workflow JSON file.
2. Import the workflow into your n8n instance.
3. Configure the 'Request YouTube Transcript' (HTTP Request) node: Update the URL field. Replace the placeholder 'Apify API_KEY Here ???' with your actual transcript service endpoint URL. If using Apify, this would be your Actor run URL. Ensure the jsonBody in the node matches the expected input format for your chosen transcript service.
4. Configure the 'Summarization Engine' (Langchain ChatOpenAI) node: Select your existing OpenAI credential or add a new one by providing your OpenAI API Key.
5. Review the 'Summarization of a YouTube script' (Langchain Summarization) node. Default settings are generally effective, but you can customize the summarization chain type or other parameters if needed.
6. The 'YouTube video URL' (Form Trigger) node is ready to use. You can test by activating the workflow and submitting a YouTube URL through the form generated by this node.
7. Activate the workflow. You can then run it manually using the form or trigger it via its webhook URL for automated processing.
