"content": "## Research any topic and email an AI report with self-healing scraper\n\n## How it works\n1. Submit a research topic via the form (topic, number of sources, recipient email)\n2. SerpApi searches Google and returns results\n3. Junk domains (Reddit, YouTube, PDFs) are filtered out\n4. Each URL is processed **one at a time** in a loop:\n - Jina.ai scrapes the page (free, no key needed)\n - Claude analyzes the content and extracts key findings\n - If a CAPTCHA or block is detected, Firecrawl retries automatically\n - If still blocked after 2 attempts, the source is marked as unavailable\n5. All findings are aggregated and Claude writes a structured executive report\n6. The report is converted to styled HTML and emailed to the recipient\n\n## Setup steps\n1. **SerpApi** \u2014 sign up at serpapi.com, paste your API key into the `SerpApi Search` node (query param `api_key`)\n2. **Firecrawl** \u2014 sign up at firecrawl.dev, paste your key into the `Firecrawl` node (`Authorization: Bearer YOUR_KEY`)\n3. **Anthropic** \u2014 create an Anthropic API credential in n8n and connect it to the three Claude nodes\n4. **Gmail** \u2014 create a Gmail OAuth2 credential in n8n and connect it to `Send Gmail`"
