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.
