BedSense is our Project. It gives farmers a second pair of eyes in the field. A farmer snaps up to three photos of a struggling plant and can speak a quick note in English or Kiswahili. Meta's SAM 3.1 isolates the plant from soil, weeds and shadow, and Muse Spark reasons from visible symptoms to the likely causes and the first three things to do. When treatment is needed, it points to nearby agrovets with realistic price ranges. When a photo isn't clear enough, it says so instead of guessing. Saved plants keep a history, so each check builds on the last. In a live test on messy farm photos, the model reached a diagnosis on five of six.
