OpenTrips: should I go out this weekend, with a number you can check

Description and use

OpenTrips gives users an instant rain and landslide risk verdict, a day‑by‑day plan, and a packing list, leveraging open data and AI models.

Problem

Users need a quick way to decide whether to go out for outdoor activities based on weather, landslide risk, and personal constraints.

Outcome

OpenTrips delivers a risk verdict with 0.899 accuracy, a detailed plan, and a map of nearby landslides, enabling users to leave the laptop and go out confidently.

Workflow

• Enter place, dates, and a constraint sentence
• Resolve place to coordinates via OpenStreetMap
• POST /risk to get rain and landslide probability from TabPFN
• POST /plan to get day‑by‑day itinerary and packing list from Qwen3 8B
• Display verdict, plan, and map with Open Meteo and NASA landslide layers
• Save plan to Postgres and provide a reusable link
