Brand Sentinel preview

An n8n workflow that monitors competitor websites on a schedule, extracts page metadata (title, description, H1), and routes the content through Gemini and OpenAI models acting as market intelligence analysts.

What it does

  • Scrapes competitor URLs via HTTP + HTML extraction
  • Analyzes brand positioning, target audience, and strategy with structured LLM prompts
  • Tags insights with keywords (Market Trends, Competitors, Digital Marketing, etc.)
  • Writes results back to Airtable for a searchable intelligence log

Architecture highlights

  • Airtable-triggered runs with error branches so a single bad scrape doesn't kill the pipeline
  • Dual-model analysis path — quick summary vs. full strategic breakdown
  • Structured output fields (Insight, Key Point, Reference, Market Trends) for downstream filtering

Why it matters

A practical template for agentic market research without a custom backend — just nodes, retries, and explicit output schemas.
