I built a fully automated news aggregation system that collects articles from multiple sources, uses AI to classify and summarize the most important ones, then delivers a professional HTML email report with expert commentary.
Workflow link: AI-Powered automated news (stock, economy...) collector with expert comment | n8n workflow template
How it works:
- News Collection: Gather updates from RSS feeds + Google Search (SerpAPI), standardize format, store in a Data Table with deduplication
- AI Processing: GPT-4.1 Nano classifies articles by topic, Gemini Flash summarizes top 15 stories per category, adds expert-style commentary
- Email Delivery: Merges summaries into a finance-themed HTML email and sends via Gmail
Cost: less than $0.02/day (about $0.60/month)
The sweet spot here is the model selection. GPT-4.1 Nano for high-volume classification (cheap), Gemini Flash for the deeper summarization (also cheap on the free tier). Running two trigger schedules to catch both morning and evening news cycles.
Use cases it covers: stock/economy news, industry monitoring, competitor tracking, academic paper digests, crisis alerts.

Happy to answer questions about the architecture.
