My friends are a big manga fan and I wanted to make them something cool for their birthday — something creative where they could make manga-style scenes easily. That's why I created Mangii app.

I used OpenAI’s new image generation, but just writing a prompt didn’t work well out of the box. I had to experiment a lot to get the manga look right.

Eventually, I ended up turning it into a small app that always keeps the manga style and lets you try different ideas.

Still early, but fun to play with. Would love any thoughts!
