Weekly AI News Digest Workflow for n8n with OpenAI GPT-4.1

Get a weekly AI news newsletter automatically—every Monday

This n8n workflow scrapes the latest AI coverage from Ars Technica, VentureBeat, and The Verge, deduplicates the articles in n8n Data Tables, and uses OpenAI (GPT-4.1) to generate a polished ~500-word Markdown weekly digest ready for publishing.

What this workflow does

• Runs on a schedule: Executes every Monday morning via a Schedule trigger.
• Loads saved Gluecrawl jobs: Fetches existing Gluecrawl job definitions for Ars Technica AI, VentureBeat AI, and The Verge AI, then merges them into a single source list.
• Scrapes fresh articles: Starts a Gluecrawl run for each source (with retries on failures) to pull article title, URL, publish date, and body.
• Deduplicates in n8n Data Tables: Checks the ai_news_articles Data Table and keeps only articles whose URLs haven’t been seen before.
• Saves new article records: Stores each new article with a truncated excerpt and metadata into ai_news_articles.
• Builds a weekly brief: Aggregates new items into a compact list capped to the 10 most recent per source.
• Generates the newsletter: Sends the brief to OpenAI to create a ~500-word Markdown digest, saving it into ai_news_digests for later publishing.

Use cases

• AI SaaS operators who need a consistent weekly update without manual research.
• Automation engineers building a reliable “AI news ingestion → newsletter” pipeline in n8n.
• Teams who want deduplicated sources and a ready-to-post Markdown newsletter draft each week.

Technical details

• Gluecrawl integration: Uses @gluecrawl/n8n-nodes-gluecrawl with saved job definitions for each site.
