what language / image libraries did you use to build this? thanks

I think this is just a thin wrapper around GPT-4 or similar? Parents I know have replaced colouring books by just asking GPT-4 , and the colouring pages it generates look exactly like the example outputs here.

Feels more likely this is the opposite - the "originals" look like hallucinations.. what is the rear suspension attached to on this "bmw"[0]? Presumably it's supposed to be an R60[1]. It magically has a lot more (accurate) parts in the colouring page[2] (bigger front and back fender, seat, engine gets fins, frame changed shape, tail has license plate holder and signals, the front brake is connected to the leaver via…

Good catch! You are really into the details.

IMO your FAQ needs an entry for: when you store uploaded photos, what will they be used for. Will my uploaded photos be used as training data for your AI models for example?

Good suggestion. We do not used the data for training. We will clarify that in FAQ.

used a fake email, but when the processing was done, it didn't work and asked me to pay for something.

The tool is not perfect. Sometimes it does not fully understand the image content. Also, right now, the image is slightly watermarked, but perfectly fine for using as coloring page.

And it seems personalized coloring page is very popular, we actually just decided to make the coloring pages free of watermarks, as our minor contribution to education. Will change the code to make that happen soon (in a few days).

Those coloring books are generated by text prompting. Here we let you create coloring pages from your own photos. Related but different.

Could be neat, but I’m really dissuaded by requiring an email signup to try it out

Use a personal domain with a default address that filters to a mailbox then use a different email address for every site you use. This plus random passwords from a password manager contains the privacy leakage, blast radius of credential loss, and keeps your mail spam free.

Or, you know, just don’t normalize indiscriminate email collection as a filter for using a service.

First thing I wanted to do was upload a family photo for my son. But of course, I don't want my family photo used for anything...

Agreed. The site should automatically delete the uploaded photos after a set amount of minutes or seconds. No reason to store them.

Earlier quoted context omitted.

Right now, we keep it for user to access it later. User can choose to delete the photo and all associated pictures, as explained in https://portraitart.app/help

We do not use the data for other purpose.

This is a good suggestion. We will definitely think about how to design the UI to satisfy both.

Did you see the goose's feet? One is a wine glass stem kind of a thing, or a liquid pour; the other is a pyramid.

Have to send user notification in email, because the processing queue could be long.

A progress bar on the website would do. And if the user closes a browser tab, you can cancel their job.
