I built an AI that diagnoses your pet's weird behavior — here's what I learned

I built an AI that diagnoses your pet's weird behavior Six months ago I built mypettherapist.com as a side project. The idea: you describe your pet's quirky behavior, and Dr. Pawsworth (our AI vet) gives it an absurd but weirdly accurate medical diagnosis. What it does You type: "My cat stares at the wall for 20 minutes and then runs through the apartment at 3am" Dr. Pawsworth responds: "Diagnosis: Nocturnal Hyperactivity Compulsion Disorder (NHCD). Severity: CRITICAL. Treatment: Accept the chaos. Schedule wall consultations. This is now your life." The tech stack Frontend : WordPress (I know, I know) Backend : FastAPI (Python) running on port 8001 AI : Claude (Anthropic) with a carefully crafted system prompt that makes it act like a slightly unhinged veterinarian Database : PostgreSQL for session management What surprised me The engagement rate is insane. People spend an average of 4+ minutes on the site — much higher than typical tool sites. The diagnosis results get shared. People
