Early skin cancer detection with AI — fast, anonymous, free

Skin cancer is one of the most common cancers worldwide, with millions of new cases diagnosed each year — and rates are rising. However, when caught early, melanoma, basal cell carcinoma and squamous cell carcinoma are curable in over 95% of cases. The key is recognising suspicious moles in time.

DermCheck combines clinically validated AI models (Med-Foundation on RunPod) with Claude Vision to assess your mole in seconds using the ABCDE rule. If anything looks suspicious, you can request an optional second opinion from a certified dermatologist — within 24 hours, GDPR-compliant and without an in-person visit.

The AI analysis is free, anonymous and does not replace a medical diagnosis. It helps you reach the right decision faster: whether to perform a self-examination, schedule a skin cancer screening with your GP, or seek a professional dermatoscopy.

Examples: Harmless vs. Dangerous

Learn the difference between harmless and suspicious moles

Harmless

Normal mole

Uniform color, symmetrical, clear borders, smaller than 6mm. No cause for concern.

  • Symmetrical
  • Uniform color
  • Smooth borders
  • < 6mm diameter
Suspicious

Irregular mole

Irregular borders, multiple colors, asymmetric. Should be examined by a physician.

  • Asymmetric
  • Irregular borders
  • Different color shades
  • Change over time
Dangerous

Possible melanoma

Highly irregular, multi-colored, blurry borders. Immediate medical examination recommended.

  • Highly asymmetric
  • Blurry borders
  • Black/red mixed
  • > 6mm diameter

The ABCDE Rule

How to identify suspicious skin changes yourself

A

Asymmetry

A mole that is not symmetrical — one half looks different from the other.

Asymmetrical moles are suspicious.
Asymmetric melanoma — the left side is noticeably thicker than the right

B

Border

Blurry, ragged, or irregular edges instead of smooth, clearly defined borders.

Watch for jagged or blurry edges.
Melanoma with irregular, ragged borders

C

Color

Different shades within a mole: brown, black, red, white, or blue.

Multi-colored moles are a warning sign.
Melanoma with different color shades: brown, black, tan

D

Diameter

Moles larger than 6mm (pencil eraser) are more suspicious.

Larger than 6mm = have it examined by a physician.
Melanoma with significant size change (> 6mm diameter)

E

Evolution

Any change in size, shape, color, or symptoms (itching, bleeding) is an alarm signal.

Always take changes seriously.

FAQ

Frequently Asked Questions

Answers about AI skin analysis, accuracy and data protection

Our pipeline combines a medical foundation model (which segments the mole and classifies it into 8 classes) with Claude Vision (ABCDE + 7-point checklist). In internal tests on the ISIC and HAM10000 datasets, sensitivity for malignant lesions exceeds 90%. For uncertain cases, we actively recommend a second opinion from a doctor.
No. DermCheck is not a medical device and does not replace a medical diagnosis. We provide a risk screening that helps you identify early on whether a mole might be suspicious. For any concerning finding, please consult a dermatologist.
The AI skin analysis is free to use and does not require an account. Optionally, we offer an assessment by a certified dermatologist for EUR 19.90 (Standard, 24h) or EUR 39.90 (Express, 6h).
If you create an account, we store your images encrypted on servers in the EU (GDPR-compliant). Anonymous scans are automatically deleted after 30 days. Images are never shared with third parties — unless you actively order a dermatologist assessment.
The ABCDE rule is the most important clinical standard for early detection of melanoma: A = Asymmetry, B = Border, C = Color, D = Diameter over 6 mm, E = Evolution (change). Our AI checks each of these criteria and outputs a score from 0–2 per letter.
We train and evaluate our models on data covering all Fitzpatrick skin types (I–VI). In your profile you can indicate your skin type, which measurably improves the analysis for darker skin tones. For very dark skin, we always additionally recommend a medical examination.
Daylight, sharp focus, the mole fills at least a quarter of the image, no flash, as perpendicular as possible. DermCheck automatically checks the image quality and gives you direct feedback (sharpness, exposure, framing).
Licensed dermatologists from Germany, Austria and Switzerland — all verified via their medical licence number. They only see the image and your AI report, no contact details. You receive their assessment as BENIGN, SUSPICIOUS or UNSURE along with a comment.
Currently a Progressive Web App (PWA): you open skincancercheckup.com in your browser, can add it to your home screen and use it like a native app — without any app store download. Works on iOS, Android and desktop.
The AI analysis takes about 3–8 seconds. The dermatologist assessment arrives within 24 hours (Standard) or 6 hours (Express). You will receive an email notification as soon as the result is ready.
