This n8n workflow automates the process of gathering trending ‘hot’ posts from selected subreddits, processing comments, generating AI-based summaries, and sending a curated daily email digest. It helps users stay updated on popular Reddit content without manual effort.
The workflow starts with a scheduled trigger set to run daily at a specific time. It retrieves subreddits specified by the user and fetches the top ‘hot’ posts for each subreddit. Posts are filtered to include only those from the last 24 hours with a score above 30, ensuring relevance and popularity.
Each post’s details, including title, URL, and main comments, are normalized and compiled into a thread structure using custom code nodes. Comments are flattened and formatted into a human-readable thread text.
Subsequently, all threads are summarized using the GPT-4 language model to produce concise insights. These summaries, along with post links, are formatted into an HTML email structure.
Finally, the email digest is sent to a specified email address, providing a comprehensive overview of trending Reddit discussions enriched with AI-generated summaries. This workflow can be customized for various topics, subreddits, or scoring thresholds, making it ideal for content curation, market analysis, or social listening.
Practical scenarios include daily market alerts, trending topic notifications, or research updates, automated to enhance productivity and keep users informed effortlessly.
