Plant Leaf Health Visual Checker

How Plant Leaf Health Visual Checker works

Add your file in the Plant image field and press Check leaf health. Everything happens in this browser tab: there is no account, and nothing you enter is sent to a server. The tool is built to run a small AI model on your own device, but no model files are published for it yet, so today it runs a transparent rule-based check instead. That check is described in full below, so you can judge exactly how much weight the result deserves.

With no model attached, Plant Leaf Health Visual Checker does not look inside the image. It reads three pieces of file metadata that the browser exposes without decoding the content: the file type (MIME type), the file size in megabytes, and whether the file name contains any of the tool's signal words ("leaf", "plant", "yellow", "brown", "spot", "dry", "wilting", "garden").

Files larger than 20 MB are flagged as large, because an on-device model would need the smaller CPU variant on a low-memory phone. Nothing about the picture or sound itself is scored, so treat the result as a check that the file is ready for local analysis, not as a summary of what it shows.

The rules are this site's own heuristic, written for a quick first pass. They are not a published clinical, statistical or industry method, and the same input always gives the same output.

Limitations

• Keyword matching does not understand meaning. Negations ("no pain"), sarcasm and synonyms are scored the same as plain mentions or not at all.
• The signal list is short and generic, so a relevant input can still score low, and an off-topic input that repeats a signal word can score high.
• Results describe the input you gave, not the real-world situation behind it. Review them yourself before acting.

Good uses for a quick local check

• Home garden triage
• Greenhouse notes
• Plant care logs
• Visual dataset labeling
