Who is this for?

This workflow is ideal for filmmakers, video producers, content creators, and location managers who need to quickly build a database of potential shooting locations without manual research and data entry.

How it works

  1. Chat Input: Start the workflow via the n8n chat interface and enter a search query (e.g., "Quiet cafes in Kyoto" or "Cyberpunk streets").
  2. Search: The workflow queries the Google Maps Places API to find matching real-world locations.
  3. AI Analysis: An AI agent (via OpenRouter) reviews the location details and writes a short, creative "Director's Commentary" highlighting its cinematic appeal.
  4. Data Entry: The location name, address, rating, Google Maps link, and the AI's commentary are automatically saved to a Google Sheet.
  5. Notification: Once all locations are processed, a summary link is sent to your Slack channel.

Prerequisites

  • n8n Version: 1.0 or later
  • Google Cloud Platform: API Key with "Places API (New)" enabled.
  • Google Sheets: A formatted sheet (see setup below).
  • Slack: An App/Bot token with chat writing permissions.
  • OpenRouter (or OpenAI/Anthropic): API Key for the LLM.

How to set up

  1. Google Sheet: Create a new sheet with the following headers in the first row:
    • 場所名 (Name)
    • 住所 (Address)
    • 評価(星) (Rating)
    • AI監督のコメント (AI Comment)
    • GoogleMapリンク (Link)
  2. Credentials: Configure your credentials for Google Maps, Google Sheets, Slack, and OpenRouter within n8n.
  3. Configuration Node: Open the node named "Workflow Configuration" and input your specific details:
    • googleMapsApiKey: Your Google Cloud API key.
    • slackChannelId: The Channel ID where you want notifications (e.g., C0123456).
    • googleSheetId: The string of characters found in your Google Sheet URL.

Customization

  • Adjust Results: Change the Limit node settings to process more locations per run (default is set to 2 to save API credits during testing).
  • Change Persona: Edit the "System Prompt" in the AI Location Analyzer node to change the AI's tone (e.g., from "Film Director" to "Real Estate Agent" or "Travel Blogger").
  • Swap LLM: You can easily replace the OpenRouter node with an OpenAI or Anthropic node if you prefer a different model.
