Monitor news sentiment trends with GPT-4o-mini, MrScraper, Slack and Notion

Description

This n8n template automatically monitors news sources daily, analyzes article sentiment using AI, and delivers structured intelligence reports to your team — all without any manual reading. It uses MrScraper to discover and extract articles, GPT-4o-mini to score sentiment and flag urgent issues, and delivers results to both Notion (for archiving) and Slack (for real-time alerts and daily digests).

Whether you're tracking brand reputation, monitoring a competitor, or staying on top of industry trends, this workflow turns the open web into a fully automated radar system that runs every morning before your team starts their day.

How It Works

Phase 1 – Trigger & Config: A Schedule Trigger fires daily at 8AM. The workflow reads your list of target news source URLs from a Google Sheet, then loops through each source one by one. Phase 2 – URL Discovery: For each news source, the Map Agent crawls the page and extracts individual article URLs. URLs are filtered using include patterns to keep only actual article links, deduplicated, and capped at your configured maxArticles limit. Phase 3 – Article Extraction: Each article URL is processed by the General Agent, which extracts the full content including title, body text, author, and publication date. Articles with fewer than 50 words or that don't mention your defined brand/topic keywords are automatically filtered out and skipped. Phase 4 – AI Sentiment Analysis: Each relevant article is sent to GPT-4o-mini with a structured prompt. The model returns a complete JSON analysis including sentiment label (positive/neutral/negative), a sentiment score from -1 to 1, a 2–3 sentence summary, key topics, tone classification, the most impactful quote, and whether the article requires an urgent response. Phase 5 – Storage & Reporting: Every analyzed article is saved as a page in your Notion database with full metadata. If an article is flagged as action-required, an immediate Slack alert is fired. At the end of each run, a Daily Digest is compiled with sentiment breakdowns, average scores, flagged items, and top article summaries — then posted to your Slack channel.
