This n8n workflow is designed to assist YouTube content creators in identifying trending topics within a specific niche. By leveraging YouTube's search and data APIs, it gathers and analyzes video performance metrics from the past two days to provide insights into what content is gaining traction. Here's how the workflow operates:

1. Trigger Setup: The workflow begins when a user sends a query through the chatmessagereceived node. If no niche is provided, the AI prompts the user to select or input one.

2. AI Agent (Language Model): The central node utilizes a GPT-based AI agent to: - Understand the user's niche or content preferences. - Generate tailored search terms related to the niche. - Process YouTube API responses and summarize trends using insights such as common themes, tags, and audience engagement metrics (views, likes, and comments).

3. YouTube Search: The youtubesearch node runs a secondary workflow to query YouTube for relevant videos published within the last two days. It retrieves basic video data such as video IDs, relevance scores, and publication dates.

4. Video Details Retrieval: The workflow fetches additional details for each video: - Video Snippet: Metadata like title, description, and tags. - Video Statistics: Metrics such as views, likes, and comments. - Content Details: Video duration, ensuring only content longer than 3 minutes and 30 seconds is analyzed.

5. Data Processing: - Video metadata is cleaned, sanitized, and stored in memory. - Tags, titles, and descriptions are analyzed to identify patterns and trends across multiple videos.

6. Output: The workflow compiles insights and presents them to the user, highlighting: - The most common themes or patterns within the niche. - URLs to trending videos and their respective channels. - Engagement statistics, helping the user understand the popularity of the content.
