    Project mention: Show HN: I Made a Web App to Bring Children's Drawings to Life | news.ycombinator.com | 2024-12-27

    This is truly amazing. Is there a 'How it Works' a 'Potentials' section?

    I work with things that push to inspire creativity and learning to foster the passion behind creativity and authentic works where otherwise we'd see how 'AI copies our work' and now we can see how AI can bring works to life and make them more fun.

    Over-all would you like to see schools adopting your project? I didn't see a contact form but would love to be able to reach out and get more insight. I think this is absolutely wonderful.

    While I know tokens and generative AI have costs, I can see the business model.

    Since you've made it a web app have you explored the possibility of making it cross platform with something like Cordova? https://cordova.apache.org/

    Perhaps setting up a bluesky social and documenting the thought process as you build on would be amazing, I'd love to see more; but would definitely like to be able to reach out in the future. Definitely bookmarked!

    paperless-ngx is successor of paperless and paperless-ng. Around that time I moved to https://teedy.io which is also opensource https://github.com/sismics/docs and also support ldap.

    I've been itching to give paperless-ngx a shot because I just love it but ldap hasn't yet ended up in the docs but the pull request was merged.

    Regardless, I just love how this project just keeps coming back to life
