Create Film Location Database with Google Maps, AI Analysis & Google Sheets

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.
