Plant Doctor: Free AI Plant Disease Diagnosis From a Photo
Plant Doctor helps plant parents diagnose sick plants from photos, compare likely causes, and follow practical treatment plans. Use the app and free plant care tools for disease checks, pest clues, watering guidance, and safer recovery steps.
How Plant Doctor works
- Take a clear whole-plant photo plus close-ups of affected leaves, stems, soil, and pests.
- Add care context such as watering, drainage, light, repotting, fertilizer, and recent changes.
- Review ranked possibilities with confidence scores instead of relying on a single guess.
- Follow staged treatment steps and monitor recovery signs before escalating.
Example diagnosis result
A root rot result may show root stress as the leading cause, explain matching clues such as soggy soil, yellow leaves, soft stems, or sour odor, then recommend pausing watering, checking drainage, inspecting roots only when symptoms justify it, and tracking new growth over the next several weeks.
Why confidence scores matter
Plant symptoms overlap. Yellow leaves can come from normal aging, overwatering, nutrient stress, pests, root damage, light changes, or temperature shock. Confidence scores help users compare the most likely causes, understand uncertainty, and choose lower-risk next steps first.
Accuracy, privacy, and safety
Plant Doctor achieved 95 percent accuracy in internal validation when users provided clear symptom photos and care context. Results are confidence scored, and uncertain cases show alternative causes. The app is not a substitute for professional advice on rare, valuable, edible, or rapidly declining plants. Learn more in the methodology, trust center, AI safety guidance, and privacy policy.

Frequently asked questions
How accurate is the AI diagnosis?
Plant Doctor achieved 95% accuracy in internal validation when users provided clear symptom photos and care context. Results are confidence scored, and uncertain cases show alternative causes instead of pretending one answer is always certain.
What makes this different from plant identification apps?
Plant ID apps tell you what your plant is. We tell you what's wrong with it and how to fix it. Our focus is on plant health, not just identification. We analyze symptoms, care history, and environment to provide actionable diagnosis.
How quickly will I see results?
Diagnosis is instant. Treatment plans show expected timelines - typically you'll see improvement signs within 3-7 days for most issues. We track progress and adjust recommendations as your plant recovers.
Is my plant data secure and private?
Yes. Plant photos are protected in transit and processed through our secure analysis pipeline to provide diagnosis, support, safety, and service improvement as described in our Privacy Policy. We do not sell your plant photos, and you can request deletion anytime.
What if the AI is wrong about my plant?
That's why we show confidence scores and multiple possibilities. If confidence is low, take clearer photos, add care context, monitor the plant, and seek expert help when symptoms spread quickly or treatment risk is high.
Do you really provide step-by-step treatment plans?
Yes! Not just 'water less' but detailed protocols: Day 1: isolate plant, Day 3: apply treatment, Week 2: monitor new growth, etc. Each plan includes progress tracking and adjustment triggers.
Can this help with rare or exotic plants?
Our AI is trained on thousands of plant species and conditions. For rare plants, we recommend the expert consultation feature where certified plant pathologists can provide specialized guidance.
What if I've already tried everything?
Perfect! We learn from your care history. Tell us what you've tried, and we'll factor that into our differential diagnosis. Sometimes 'everything' doesn't include the right thing - we help you find it.
