📌 What is the Plant Health Calculator?
The Plant Health Calculator is a smart, interactive web application that helps gardeners, plant parents, and farmers quickly identify plant diseases, pest infestations, nutrient deficiencies, and watering issues. It combines two powerful diagnosis modes:
Symptom Checker
Select visual cues like yellow leaves, brown spots, sticky residue, or drooping stems. The rule-based engine instantly matches symptom combinations to common problems (root rot, powdery mildew, sap-suckers, etc.) and provides actionable treatment steps.
AI Photo Analysis
Powered by Google Gemini 2.5 Flash — upload a leaf or whole-plant photo, and AI recognizes diseases, pest damage, or environmental stress. Returns a structured diagnosis with causes and treatment plan.
💡 Why it matters: Early detection saves plants. The calculator gives instant, evidence-based advice — from overwatering fixes to organic fungicide recommendations — suitable for beginners and experts.
📌 Powerful features — At a glance
- Dual diagnostic engines – symptoms + AI vision
- 9+ symptom categories including yellowing, curling, white powder, holes, mushy stems
- AI plant recognition – detects 30+ diseases/pests (leaf spot, blight, aphids, spider mites)
- Action-oriented treatment – watering schedules, neem oil recipes, repotting steps
- Confidence scoring – shows diagnosis reliability
- Gemini 2.5 Flash integration – fast, accurate photo insights
- No registration – use directly, zero friction
- Mobile-optimized – camera upload & responsive interface
📌 How to use the Plant Health Calculator
To Use this tool, follow these two main paths:
Path 1: Symptom Checker (no photo needed)
- 1 Navigate to “ Symptom Checker” tab (active by default).
- 2 Tick all symptoms you observe: yellow leaves, brown crispy edges, drooping, white powder, holes, sticky residue, brown spots, curling or mushy stem.
- 3 Click “ Analyze Plant Health” — the tool instantly computes matches based on internal plant pathology rules.
- 4 Read the result: diagnosis name, confidence level, and a detailed action plan (watering advice, fungicide, pruning, etc.).
Path 2: AI Photo Analysis (Gemini vision)
- 1 Switch to “AI Photo Analysis” tab.
- 2 Click the upload area (or tap) to select a plant image from your gallery or take a photo with your device camera.
- 3 After selection, the image preview appears and AI analysis starts automatically (powered by Google Gemini).
- 4 Within seconds, you receive: DIAGNOSIS → CAUSES → TREATMENT steps. Even detects subtle issues like early blight, edema, or nutrient burn.
- 5 Use “Clear / Start Over” button to reset and analyze another plant.
⚡ Pro tip: For accurate AI diagnosis, take a clear close-up of the affected leaf or stem in natural light.
📌 Frequently Asked Questions
🌿 Is the Plant Health Calculator free? Do I need to create an account?
Absolutely free! No signup, no credit card required. The symptom checker works offline in your browser. AI photo analysis uses a demo API key — you can also bring your own Gemini API key for enhanced privacy.
🌿 How accurate is the AI photo diagnosis?
The tool uses Google Gemini 2.5 Flash, which achieves expert-level recognition for common plant diseases (powdery mildew, leaf spot, rust, mosaic virus) and insect damage. Accuracy depends on image quality and clarity. For best results, photograph affected areas without shadows. The symptom checker is equally reliable for typical houseplant issues.
🌿 What types of plants does it support?
From tropical houseplants (Monstera, Fiddle Leaf Fig, Pothos) to vegetables (tomatoes, peppers, cucumbers), succulents, herbs, and ornamental shrubs. The AI model is trained on general botanical datasets, while symptom rules cover broad plant physiology (overwatering, nutrient deficiency, fungal/bacterial, insect pests).
🌿 Can I use the AI analysis without an internet connection?
The Symptom Checker works fully offline once the page loads (no server required). AI photo analysis requires an internet connection to communicate with Gemini API. Both methods complement each other perfectly.
🌿 Are my uploaded photos stored or shared?
No. Your photos stay on your device locally while being sent to Gemini API for analysis; they are not stored on any server beyond the temporary request. The tool does not retain any image data. For ultimate privacy, you can also use the symptom-only mode.
🌿 My plant has multiple symptoms — why does the diagnosis combine them?
The plant health calculator uses priority-based reasoning. For example, mushy stem + yellow leaves triggers root rot first because it’s life-threatening. If symptoms indicate overlapping issues (e.g., sticky residue + holes), the tool highlights the primary cause and gives holistic advice. The AI photo analysis also synthesizes multiple visual cues.
🌿 Does it work on mobile phones and tablets?
Yes! Fully responsive design works seamlessly on iOS, Android, and any modern browser. You can take a photo directly from your phone camera and get an instant analysis, all within the same interface.
🌿 How do I get the most accurate treatment recommendations?
Combine both tabs! Use symptom checker for a quick rule-based diagnosis, then verify with a photo upload for AI confirmation. Always follow the treatment steps: adjust watering, isolate plant if contagious, apply recommended organic sprays, and monitor progress.
