I've had this on my side project todo list for a while but was waiting until image editing models got good enough to make something that really works.

Here's the link: https://fitpic.app

At first I just wanted to spend a couple of days having fun building a basic demo but I was so impressed with the results that I decided to spend another week making this into a real product.

It's all powered by Google's new Nano Banana/Gemini Flash Image 2.5 model, with the catalog powered by https://trychannel3.com/ (recently on HN) and Google image search.

It does require signup to use once for free and then credit purchases (I would like to have it be usable without signup but the model is not cheap and I don't want to bankrupt myself by opening it up to abuse).

I did throw a quick page together with some examples here though: https://fitpic.app/examples

I know HN is very well-dressed and style-conscious so I hope someone here finds it interesting or useful.
