Quick answer
Yes — you can check your skin online for free without downloading an app. ScanSkinAI runs entirely in your phone browser. Take a photo of the mole, spot or rash, and you'll get an AI assessment in around 30 seconds. It's a screening tool, not a diagnosis, but it's the fastest way to decide whether to wait, watch, or see a doctor.
Key takeaways
- Check your skin online without downloading an app — works in any modern phone browser.
- ScanSkinAI gives a screening result in around 30 seconds.
- Free for the first scan — no credit card needed to try.
- Results are not a diagnosis. They help you decide whether to monitor or see a doctor.
- Best for moles, spots, rashes, bumps and skin changes you can see and photograph.
Most people who search 'check skin online' are not doing research — they've just noticed something they don't like the look of, and they want to know if it's serious before bed. You're not alone, and you don't need to install anything to get an answer.
ScanSkinAI was built around this exact moment. You open the link in your phone browser, take a photo of what's worrying you, and the AI returns a screening result with a confidence score and a recommendation: monitor at home, or seek professional review.
Why no download matters
App downloads are friction. They mean an Apple ID or Google account, 50–200 MB of storage, permissions, updates, and an icon you'll forget to delete. For a one-off worry — 'is this mole normal?' — that's too much.
A browser-based check works on any phone made in the last six years. It also means you can check your skin from a borrowed phone, a work laptop, or a tablet, without leaving any trace on the device.
What you'll need
Three things: a phone with a working camera, decent lighting (a window, a desk lamp, or a bright bulb), and the area of skin you want to check. That's it.
- A clean lens — wipe it on your sleeve before the photo.
- Even, indirect light. Avoid harsh shadows and direct flash.
- Frame the mole or spot in the centre, filling about 60% of the photo.
- Hold steady. Tap the spot on screen to focus before capturing.
What the result tells you
ScanSkinAI returns a likely category (for example, common nevus, seborrheic keratosis, dermatofibroma, suspicious lesion), a confidence score, and a recommendation.
If the AI flags anything that looks atypical, you'll be advised to seek a professional review. ScanSkinAI is a Class I medical device under UKCA, but it does not replace a dermatologist or biopsy.

Who is this useful for?
When should you seek professional advice?
See a doctor or dermatologist promptly if you notice:
- A mole that is changing in size, shape or colour over weeks
- A skin lesion that bleeds, crusts or won't heal after 4 weeks
- A new mole appearing after age 40
- A rash that spreads quickly, blisters, or comes with fever
- Any lesion that is asymmetrical with irregular borders or multiple colours
What AI skin analysis cannot do
- It cannot diagnose skin cancer, melanoma or any disease.
- It cannot replace a dermatologist, GP or other clinician.
- It cannot replace dermoscopy, biopsy or clinical examination.
- It cannot prescribe medication.
- Image quality (focus, lighting, framing) materially affects results.
- For worrying or rapidly changing symptoms, always seek medical advice.
Frequently asked questions
Do I really not need to download an app?
Correct. ScanSkinAI runs in your phone browser. You can optionally save it to your home screen as a PWA for one-tap access, but no app store install is required.
Is the online skin check free?
Yes — your first scan is free and you don't need a credit card. Paid plans exist for ongoing tracking and dermatologist review, but the basic AI screening is free to try.
How accurate is the online check?
ScanSkinAI uses a DINOv2-based model with around 95% concordance against dermatologist labels in our internal validation set. It is a screening tool, not a diagnosis. Always seek a doctor for anything suspicious.
Will my photo be saved?
Photos are processed for the AI scan and stored securely against your account if you sign in. If you scan as a guest, the image is used only for that scan. See our privacy policy for full detail.
Which phones work?
Any iPhone or Android phone made in roughly the last six years with a modern browser (Safari, Chrome, Edge, Samsung Internet). No specific OS version is required.
Can I check more than one spot?
Yes. You can run multiple scans in the same session and compare results. Saving to a free account lets you track changes over weeks or months.
