PlantCareAI is a weather and context-aware AI plant advisor that gives personalized care guidance based on each plant's history and live local weather data. I built it solo after getting laid off in August 2025. Here's what I actually learned about building with AI when no one else is on the team. What I built PlantCareAI is a weather and context-aware AI plant advisor. Free users can enter a plant name and their location to get care recommendations from the AI. Signed-in users get a personal plant dashboard where they can track their plants, set watering and care reminders, and add journal entries. The AI uses each plant's context, plus live weather data from OpenWeather , to tailor its advice. The stack: Python/ Flask , PostgreSQL (via Supabase ), Tailwind CSS, plain JavaScript, Render for deployment, Cloudflare for DNS, and Anthropic's Claude Haiku as the primary LLM with Google Gemini as a fallback, orchestrated through LiteLLM . Authentication is OTP email-based. Payments are handled through Stripe.…
