Generate Weather-Based Date Itineraries with Google Places, OpenRouter AI, and Slack

🧩 What this template does

This workflow builds a 120-minute local date course around your starting point by querying Google Places for nearby spots, selecting the top candidates, fetching real-time weather data, letting an AI generate a matching emoji, and drafting a friendly itinerary summary with an LLM in both English and Japanese. It then posts the full bilingual plan with a walking route link and weather emoji to Slack.

👥 Who it’s for

Makers and teams who want a plug-and-play bilingual local itinerary generator with weather awareness — no custom code required.
