n8n Competitor Pricing & Launch Tracker with OpenAI, Sheets & Slack

Track competitor pricing + launches automatically—twice a week, with OpenAI, Google Sheets, and Slack alerts

This n8n workflow monitors your competitors’ homepage content on a schedule, uses OpenAI to extract pricing and launch signals, logs everything to Google Sheets, and alerts your team in Slack. Every Friday, it generates a weekly digest and delivers it via Gmail and Slack.

What this workflow does

• Runs on a schedule (Tuesday + Friday mornings): processes a configured list of competitor homepages.
• Fetches and validates each homepage: downloads the page over HTTP, normalizes the response, and checks that enough content is returned.
• Handles short/failed responses: if the page content is too short, it writes an error row to a Google Sheets “Errors” tab and posts a failure message to Slack.
• Extracts structured market signals with OpenAI: sends the page text to an OpenAI chat model to return JSON containing signals such as pricing, launches, promos, social proof, or hiring.
• Logs sightings + alerts in real time: when a signal is found, the workflow appends the sighting to the Google Sheets “Sightings” tab and posts a Slack alert including the headline, details, urgency score, and URL.
• Creates a Friday weekly digest: reads the week’s sightings from Google Sheets, uses an OpenAI chat model to write a short digest, then emails it via Gmail and posts a summary to Slack.

Use cases

• SaaS operators monitoring competitor pricing changes and promotional activity.
• Product teams tracking launch signals from homepage updates and announcements.
• Automation engineers needing a repeatable n8n workflow for web monitoring + AI extraction with audit trails in Google Sheets.

Technical details

• Integrations: OpenAI, Google Sheets, Slack, Gmail (plus HTTP page fetch).
• Core n8n node behavior: conditional logic (if), data shaping (set), combining outputs (merge), splitting lists (split out), and notifications (slack, gmail).
• Setup: add OpenAI credentials for the two AI steps (e.g., models like gpt-4o-mini and deepseek-v4.1-flash), create a Google Sheet with “Sightings” and “Errors” tabs, and connect Slack.
