Leafy: A Houseplant You Can Talk To, Powered by an Open-Weight Model

Description and use

Leafy is a mobile app that lets users chat with houseplants using weather and watering schedule data to ensure timely care.

Problem

Users forget to water plants because they are distracted by work, leading to plant neglect.

Outcome

Leafy delivers a concise, plant‑centric chat experience that integrates real‑time weather and scheduling data, reducing plant neglect and encouraging timely care.

Workflow

• 1. User opens Leafy and views plant profile cards with species, light, soil, and watering schedule.
• 2. User taps the Chat button on a card to initiate a conversation with the plant persona.
• 3. The app constructs a prompt using the plant’s profile, next watering date, and live weather data from Open‑Meteo.
• 4. Google Gemini AI generates a first‑person, character‑based reply that references the plant’s thirst level and current weather.
• 5. The app displays weather advisories (e.g., misting when humidity is low) using threshold rules.
• 6. User reads the response and performs the suggested care action, then closes the app.
• 7. The app logs the interaction for future reference.

Evidence

Leafy is a React Native (Expo) app built around that problem.

Every card shows the next watering time "Tomorrow at 09:30 AM", and tapping it opens a full care sheet...

You can chat with your plant. Every card has a Chat button. The reply comes in first person, in character, from the plant itself.

The part I'm most excited about: you can chat with your plant... It knows its own species, when it's next due for water, and what the weather is doing outside right now (live temperature and humidity).

Leafy is designed so the screen is the shortest part of the experience. The goal is a check‑in of under a minute...
