Krap AI is a free platform developed on a voluntary basis to support Thailand's AI future. It can be used for general conversations, and development is ongoing to enable flood forecasting by processing open-source data—a crucial capability for managing natural disasters like floods in Thailand.
You can chat with Krap AI to get the latest updates on Thailand flood disasters. While Krap AI utilizes its own dedicated flood AI model, it can also employ other AI models as a fallback during periods of high traffic.

How Do You Check a Road Before Driving in Thailand?
A report describes one place at one time, and an area with no report isn't proof of a dry road.
The Krap flood map shows each report as a pin with the place, the filing time and, when recorded, the depth, road status and photo. Route search takes a start and a destination anywhere in Thailand and lists reports within about 500 m of the road you pick.
