Know exactly what
that spot is.
Snap a photo of suspicious mold and get an instant AI read on what it is and how worried to be — backed by a real 53-species household mold compendium, not a one-line guess.
A real answer, not a guess.
Most mold apps stop at a one-line verdict. Mold Identifier goes further — every feature is built to earn your trust in the result.
Instant AI Identification
Snap a photo and get a species match, risk tier, and next steps in seconds — add a quick note (e.g. "near a leaky pipe") for a sharper result.
53-Species Compendium
Browse common household mold types anytime — not just after a scan. Real reference photos, risk tiers, common locations, and look-alikes.
Honest Confidence
When a result isn't clear-cut, you'll see that too — plus the closest alternate match. Never a guess dressed up as certainty.
Danger-Tier Guidance
Every result comes with a clear risk tier and what to do next — from basic cleaning to calling a professional inspector.
