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 licensed dermatologist - within 24 to 48 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.

03Medical Knowledge
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.
- B
Border
Blurry, ragged, or irregular edges instead of smooth, clearly defined borders.
→ Watch for jagged or blurry edges.
- C
Color
Different shades within a mole: brown, black, red, white, or blue.
→ Multi-colored moles are a warning sign.
- D
Diameter
Moles larger than 6mm (pencil eraser) are more suspicious.
→ Larger than 6mm = have it examined by a physician.
- 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 – for a scan with up to 5 photos the advanced AI report is included at no cost. Only from the 6th photo of the same spot does the report cost a one-time EUR 4.99. An assessment by a certified dermatologist costs EUR 19.99 (Standard, reply within 48 hours) or EUR 39.99 (Express, within 24 hours).
A detailed document about your specific scan, available immediately and included at no cost for up to 5 photos (a one-time EUR 4.99 from the 6th photo on): each ABCDE criterion is explained in detail for your image, plus a concrete monitoring and photo plan and preparation notes for a possible doctor's appointment. The report is generated automatically from your AI assessment, is printable, and does not replace a medical diagnosis.
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 advanced AI report is available immediately after payment. The dermatologist assessment arrives within 48 hours (Standard) or 24 hours (Express). You will receive an email notification as soon as the result is ready.
