The project runs inference locally, storing scan history and notes in a SQLite journal, and nudges users toward outdoor plant inspections rather than extended screen time. It was submitted to the Hacktoberfest Open-Source AI Challenge Week 1 \"Touch Grass\" and is available on GitHub with a browser-based demo.", "body_md": "*This is a submission for the [Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass](https://dev.to/challenges/hacktoberfest-week1-2026-10-05).*\n\n**GitHub Repository:** [PlantGuard AI on GitHub](https://github.com/lalit-oli-mohan-479/PlantGuard-AI---Open-Source-Plant-Disease-Detector)\n\n**Live Demo:** [Try PlantGuard AI](https://lalit-oli-mohan-479.github.io/PlantGuard-AI---Open-Source-Plant-Disease-Detector/)\n\nIn an age where developers and tech workers spend 8 to 10 hours a day glued to glowing screens, our connection with the physical, living world can easily deteriorate. When a beloved balcony tomato plant develops yellow halos or an apple tree shows olive-green spots, our modern reflex is to grab a phone, search endlessly, and sink deeper into screen fatigue.\n\nExisting commercial plant identification apps can make this experience even more frustrating:\n\n**PlantGuard AI** was built to offer a different approach.\n\nCreated for the **Hacktoberfest Open-Source AI Challenge Week 1: “Touch Grass,”** PlantGuard AI is an open-source plant disease screening tool and garden care companion designed to run locally.\n\nIt uses open-weight computer vision not to keep you glued to your screen, but to **help you step away from your desk, get some sunlight, and reconnect with your garden.**\n\n🌱 **Explore the project:** [GitHub Repository](https://github.com/lalit-oli-mohan-479/PlantGuard-AI---Open-Source-Plant-Disease-Detector)\n\nPlantGuard AI uses a MobileNetV2 architecture fine-tuned on the PlantVillage dataset to identify visual patterns associated with plant diseases and healthy leaves.\n\nThese results represent the project's reported benchmark performance, not a guarantee of accuracy for every real-world garden condition.\n\nPlantGuard AI treats AI predictions as **probabilistic screening aids, not definitive diagnoses**.\n\nEach of the 38 classes includes a human-reviewed care profile designed to help users understand symptoms and choose sensible next steps.\n\nProfiles include:\n\nRecommendations are intended as general gardening guidance. Treatments should be selected according to the plant, likely cause, and local growing conditions.\n\nThis is the heart of PlantGuard AI.\n\nInstead of ending with an AI prediction, the application gives users a customized checklist that encourages them to inspect their plants outdoors.\n\n**Interactive Milestone Rewards:** After completing the outdoor inspection, users can click **“Mark Outdoor Inspection Complete”** to record their garden visit and celebrate time spent caring for living plants.\n\nThe goal is simple: use AI as a bridge to real-world action, not as another reason to stay indoors.\n\nThe desktop application stores scan history, prediction confidence, personal notes, and outdoor follow-up statuses in a local SQLite database:\n\n`data/journal.db`\n\nFeatures include:\n\n`Pending Outdoor Check`, `Grass Touched: Inspected Outdoors`, and `Recovering`.\n**Privacy by design:** The local desktop workflow is designed to keep plant photos, notes, and inference on the user's machine rather than uploading them to third-party servers.\n\nThe browser-based showcase uses browser `localStorage` for its client-side journal, which is separate from the desktop application's SQLite database.\n\nExperience PlantGuard AI in two ways.\n\n**Try it here:** [Open the Interactive GitHub Pages Demo](https://lalit-oli-mohan-479.github.io/PlantGuard-AI---Open-Source-Plant-Disease-Detector/)\n\nYou can explore the interactive showcase from a phone, tablet, or desktop browser.\n\n**What you can do:**\n\n`localStorage`.\n*Note: The browser showcase and the full local desktop application are separate experiences. Check the repository documentation for the implementation details and capabilities of each.*\n\nRun the Python application locally to explore the complete desktop workflow.\n\n**Prerequisites**\n\n**Quickstart Commands**\n\n```\n# 1. Clone the repository\ngit clone https://github.com/lalit-oli-mohan-479/PlantGuard-AI---Open-Source-Plant-Disease-Detector.git\n\n# 2. Enter the project directory\ncd PlantGuard-AI---Open-Source-Plant-Disease-Detector\n\n# 3. Install dependencies\npip install -r requirements.txt\n\n# 4. Launch the local application\npython app.py\n```\n\n**Get the code:** [View the PlantGuard AI GitHub Repository](https://github.com/lalit-oli-mohan-479/PlantGuard-AI---Open-Source-Plant-Disease-Detector)\n\nPlantGuard AI is built around a simple idea: technology should help us engage more meaningfully with the world around us.\n\nBy combining accessible computer vision, transparent prediction confidence, local data storage, and practical gardening checklists, the project aims to make plant health screening more approachable while encouraging users to spend less time scrolling and more time caring for their plants.\n\nIt is not about replacing hands-on gardening expertise. It is about using AI to help people ask better questions, inspect their plants more carefully, and take informed next steps.\n\nPlantGuard AI is an open-source project, and contributions are welcome.\n\n🌱 **GitHub:** [Star the repository, explore the code, or contribute](https://github.com/lalit-oli-mohan-479/PlantGuard-AI---Open-Source-Plant-Disease-Detector)\n\n🌐 **Live Demo:** [Try PlantGuard AI](https://lalit-oli-mohan-479.github.io/PlantGuard-AI---Open-Source-Plant-Disease-Detector/)\n\nBuilt for Hacktoberfest. Inspired by nature. Designed to bring people back to their gardens.\n\n**Touch grass. Inspect a leaf.
