    The comics look pretty Miyazaki-inspired, like all of the comics I've seen lately. I've kinda started to dislike this look because it's _everywhere_ that low-effort comics are these days.

    Maybe worth trying to train a better style for this. This is probably something where you could put a little effort in up-front (ie: using a model that's for segmentation to get outlines, using some classic image-processing for boundary detection) and then have AI touch it up a little more lightly and a less of the "default" style.

    Also, do you have AI images for the "real world" samples on the left? They have a certain "I don't exactly know what, but it's creeping me out" vibe.

    from clevercoloringbook.com:

        > Please only upload photos that are in line with OpenAI's Usage Policy.
        > We are not able to include any photos that do not follow their policy in the final printed book.
    

    from openai.com/policies

        > Editing uploaded images or videos that contain real people under the age of 18 is not permitted.
    

    The first two sample pictures on the page contain of adolescent children. Are you concerned about this apparent contradiction?

    This is a cute and simple idea!

    I'd like to see what a real physical book looks like before I buy it though. Do you have real pictures of a printed one?

    I think our kids would appreciate seeing the original (even if a small thumbnail) along side it. You can't always tell from these AI drawings that it was originally you and your family.

    Also, it's REALLY expensive. $30 for a book that my kids will draw on in one or two nights and then never touch again is probably too much.

    Nice and simple! I'm excited for all the fun micro businesses that get enabled by the new image API.

    Things like your coloring book, instant sticker/tshirt/swag creation, video game assets, etc.

    Also love the "tap 5 times for a discount" feature.

    You'll want to really drive home the niche (through your feature set) that it's for family photos, because the generic photo to AI vectorized coloring book service has been done to death.

    I like GPT wrapper's that let me personalize/customize existing real world things, and this a good example of that. I like it.

    For what it’s worth (and it’s probably not much), it doesn’t cost that much to commission comic book-style art from an actual artist online. When you do that, the proceeds go to an artist, not to an AI company that stole from them and a software developer who wrote a wrapper around their API.

    Why not just an option to print the image?

    Is there somewhere to download a PDF to print out?

    For anyone looking for a prompt to do this manually, it seems to be as simple as this:

    > Generate a version of this photo that can be used as a coloring sheet

    Cool idea and really nice looking site.

    Pricing is quite high – 24 pages maximum for $23.99. There are 100-page coloring books on Amazon for $5.00, and the age group that really would be using this is not going to remember what was on the page a week from the day they did it.

    Maybe it can work in the nice of "adult coloring books" – I've seen some social media content where people really go crazy on coloring books, and being able to get nice physical copy to work off could appeal there.

    Seems like this cat (and various variants in similar settings) was a top rated image in Sora's explore/images a week ago. Was it yours, should it be credited, or did you hit edit prompt<enter> to get a variant?

    No worries, just wondering how that should work.

    Nicely done, Ive always wanted something like this for my family pics. you think AI-generated art will ever feel as special as something handmade?

    For those interested in building something similar, I prompted a story book generator using v0 and Gemini’s image generation a few weeks ago:

    Why don't you use canny/HED filter :O? (seems pretty overkill for this job..)
