How it works

From photo to answer in three steps

No downloads, no waiting rooms. RashScan runs entirely in your browser and talks to the same AI engine that powers our mobile app.

Snap or upload a photo

Take a clear, well-lit photo of the affected skin — or drag and drop an existing image. Add a few quick details like when it appeared and whether it itches.

AI analyzes your skin

Our model compares your photo against thousands of verified dermatology cases, weighing your symptoms to rank the most likely conditions.

Get clear guidance

See the likely condition with a confidence score, severity level, care recommendations — and importantly, when you should see a doctor.

What people say

Peace of mind, delivered by photo

"My toddler woke up covered in red spots on a Sunday. RashScan suggested it was likely heat rash and told me exactly what to watch for. The pediatrician confirmed it the next day."

Sarah M.

Parent of two

"I have sensitive skin and the product scanner is genius. I photograph the ingredient list in the store and know in a minute whether a moisturizer will set me off."

Jordan T.

Eczema-prone skin

"It flagged my 'harmless spot' as something worth showing a dermatologist. It turned out to need treatment. I'm so glad I didn't wait another month."

FAQ

Questions, answered

Yes — with the right expectations. RashScan compares your photo against thousands of dermatologist-verified cases and ranks the most visually similar conditions with a confidence score. It's a powerful first step for understanding what you're likely dealing with, but it is not a diagnosis. Confirming any condition requires a qualified clinician.

Yes. Scanning a rash or a product is free, with no account and no credit card. A Pro plan with cloud sync, rash tracking over time and shareable PDF reports is coming soon — but the core scanner will always be free.

We never ask for your name, email or any identity information. Scans are linked only to an anonymous device ID stored in your browser, images are processed over an encrypted connection, and you can clear your entire history at any time from inside the app.

The model recognizes 50+ of the most common skin conditions, including contact dermatitis, eczema, heat rash, hives, psoriasis, fungal infections like ringworm, insect bites, and more. For unusual or ambiguous presentations, it will tell you when an in-person exam is the right next step.

See a doctor promptly if a rash spreads rapidly, blisters, is accompanied by fever or difficulty breathing, involves the eyes or mouth, or if any mole changes shape, size or color. RashScan flags these red-flag signs in its results, but severe or fast-changing symptoms always warrant immediate medical care.

The training data spans a wide range of skin tones, ages and body areas, and we continuously improve coverage. Clear, well-lit photos give the best results on every skin tone — natural daylight works best.
