"content": "## \ud83d\udd75\ufe0f Competitor Change Monitor\n\nAutomatically tracks your competitors' websites on a weekly schedule, detects what changed, and delivers an AI-written intelligence digest as a Gmail draft \u2014 ready to share with your team.\n\n---\n\n## \u2699\ufe0f How It Works\n\n**1. Weekly Schedule**\nTriggers automatically once a week. You can adjust the frequency directly in the Schedule Trigger node.\n\n**2. Define Competitors**\nA Code node where you list the competitors you want to monitor. Each entry includes a `name`, `url`, and `watch_for` description (e.g. \"pricing changes\", \"new features\").\n\n**3. HTTP - Fetch Competitor Page**\nFetches the raw HTML of each competitor URL via an HTTP GET request. Runs once per competitor in the list.\n\n**4. Track Snapshot Changes**\nStrips all HTML tags, scripts, and styles down to clean readable text (up to 12,000 characters per page). Compares the current text against the last stored snapshot using n8n's built-in static data \u2014 no external database needed. Flags whether the page has `changed: true` or `false`.\n\n**5. Build Digest Prompt**\nCollects all changed pages and assembles a structured prompt for the AI. If nothing changed, it instructs the AI to produce a short no-change digest instead.\n\n**6. OpenAI - Summarize Competitor Changes**\nSends the prompt to GPT-4.1-mini which returns a plain-text competitive intelligence report covering:\n- Executive summary\n- Material changes by competitor\n- Suggested response actions\n- Watch items for the next run\n\n**7. Format Digest Email**\nFormats the AI output into an HTML email body and adds a date-stamped subject line like `Competitor change digest - 2026-05-01`.\n\n**8. Gmail - Draft Digest**\nSaves the formatted digest as a Gmail draft addressed to your recipient. Nothing is auto-sent \u2014 always review before sending.\n\n---\n\n## \ud83d\udd27 Setup Checklist\n\n- [ ] Open **Define Competitors** and add your competitor `name`, `url`, and `watch_for` values\n- [ ] Open **Build Digest Prompt** and replace `replace-me@example.com` with your recipient email\n- [x] Connect your **OpenAI** credential to the OpenAI node\n- [ ] Connect your **Gmail OAuth2** credential to the Gmail node\n- [ ] Run the workflow **once manually** to store the first baseline snapshots\n- [ ] **Activate** the workflow \u2014 weekly monitoring begins automatically\n\n---\n\n## \u26a0\ufe0f Things to Know\n\n- The **first run stores baselines only** \u2014 no digest is generated until the second run detects a diff\n- Snapshots are stored in **n8n workflow static data** \u2014 clearing static data resets all baselines\n- Page text is capped at `12,000` characters per competitor to stay within token limits\n- Sites with heavy JavaScript rendering may return incomplete snapshots via HTTP \u2014 consider a headless browser node for those\n- Adjust the schedule in the **Weekly Schedule** node to run daily or bi-weekly as needed"
