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

Description

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
Chat Input: Start the workflow via the n8n chat interface and enter a search query (e.g., "Quiet cafes in Kyoto" or "Cyberpunk streets").
Search: The workflow queries the Google Maps Places API to find matching real-world locations.
AI Analysis: An AI agent (via OpenRouter) reviews the location details and writes a short, creative "Director's Commentary" highlighting its cinematic appeal.
Data Entry: The location name, address, rating, Google Maps link, and the AI's commentary are automatically saved to a Google Sheet.
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
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)
Credentials: Configure your credentials for Google Maps, Google Sheets, Slack, and OpenRouter within n8n.
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.
