Summarize RSS feeds into a daily Slack digest with OpenAI GPT-4o Mini

Quick Overview This workflow runs every morning at 8 AM to pull the latest items from an RSS feed, uses OpenAI (gpt-4o-mini) to summarize the top 10 into a themed daily digest, and posts the result to a Slack channel.

How it works 1. Runs every day at 8 AM using a schedule trigger. 2. Reads the latest items from an RSS feed URL (default: Hacker News front page). 3. Keeps only the first 10 feed items and compiles their titles and links into a single list. 4. Sends the compiled list to OpenAI (gpt-4o-mini) to generate a short digest grouped into 3–5 themes. 5. Posts the generated digest to a Slack channel as a formatted message.

Setup 1. Add your OpenAI API credentials for the Chat model used to create the summary. 2. Add your Slack credentials and confirm the target channel (default: daily-digest) exists and is accessible. 3. Update the RSS feed URL(s) to the sources you want and adjust the schedule time or the “top 10” limit if needed.
