Show HN: I'm a dermatologist and I vibe coded a skin cancer learning app(molecheck.info)

Coded using Gemini Pro 2.5 (free version) in about 2-3 hours.

Single file including all html/js/css, Vanilla JS, no backend, scores persisted with localStorage.

Deployed using ubuntu/apache2/python/flask on a £5 Digital Ocean server (but could have been hosted on a static hosting provider as it's just a single page with no backend).

Images / metadata stored in an AWS S3 bucket.

Why would a dermatologist want to just remove but not biopsy a suspected facial skin cancer?

sungam 9/8/2025|

There would be no reason to do this - skin lesions removed are almost always sent for pathological analysis even if expected to be harmless

Would you like to hire "Cyber security engineer for vibe-coded applications" ?

sungam 9/8/2025|

Not at the present time. I think if the project takes off I will move it to static hosting anyway to reduce the attack surface.

Interesting. I wish there existed an app for actually finding a cure for every killer decease.

sungam 9/7/2025|

Haha I think will need more than just an app! But in all seriousness, the potential for applying modern AI techniques to DNA and protein sequence analysis, structural analysis and regulatory network modeling is immense and we have only scratched the surface so I am sure it will accelerate biological discovery.

I absolutely love the reality check on doctors coding and skin cancer, great work!

Learned quite a bit and seems like a basic but necessary thing to know about!

Thanks, I'm glad you found it useful. My patients were constantly asking for a way to learn what skin cancer looked like beyond the ABCDE rule and I wanted to try and introduce a gamification aspect to it.

Thanks for the reminder to schedule the annual dermatology appointment.

How good is ChatGPT or Claude at classifying these? Have you tried?

sungam 9/8/2025|

Not tried but my guess is ChatGPT will be quite accurate but get a small proportion wrong. The challenge with skin cancer is that we cannot afford to miss even 1:10,000 cases

Are doctors that accurate?

The two links in your menu don’t work but otherwise this is awesome!

sungam 9/7/2025|

Thanks - I wasn't expecting anyone to use the app apart from perhaps a few patients and definitely didn't expect #2 spot on HN

Will add asap but currently focused on answering questions!

Fortunately my £5 Digital Ocean server is coping fine so far...
