⚙ How it works

From a phone in your pocket to a map on the web.

  1. 01

    Snap and share

    Open the Telegram bot on your phone — send a photo of what you see, then share your location with one tap. The bot is mobile only.

  2. 02

    Auto-classified

    A vision model reads the photo, identifies the issue (litter, algal bloom, oil sheen, dead fish, dumped objects) and scores how serious it looks.

  3. 03

    Pinned to the map

    Reports appear on the map shortly, pinned to the canal's actual name.
