MangaManzi A BYOK GPT image 2 Manga Creation Studio
MangaManzi A.I BYOK GPT image 2 Manga Creation Studio
Spent the last few months building MangaManzi because every AI image tool fails the same way at manga: the character drifts. Page 1 she's got curly hair, page 2 the curls are straight, page 3 her outfit changed colors. You can't tell a story when your protagonist isn't recognizable.
So I built around a reference card system instead of text prompts.
How it works: you set up four cards per project — Character (4-angle turnaround), Props, Environment, Scale sheet. Build them once, reuse forever. Every panel you generate sends the full card stack to GPT Image 2 as visual input, not just text. The model sees her face, her outfit, her gear, her world on every call. Consistency stops being luck.
Two passes per page: lineart first (pure ink, no tones), then color (cell-shaded, locked palette). Director's notes per panel. A4 ratio. PDF export per chapter. Claude Sonnet 4.6 handles the prompt architecture and panel direction in the background.
It's free. No subscription, no credits, no upsell. You bring your own OpenAI key and Anthropic key. You pay the providers directly — usually a few cents to a couple dollars per page depending on quality settings. I'm not in the loop.
Built for two kinds of people:
- Artists who already have original character designs and want to scale to full pages using their own references
- Storytellers with no art skill who want manga that actually looks coherent
If you've tried this with Midjourney or SD and given up on consistency, this is a different approach. Reference cards are ingredients, GPT Image 2 is the chef.
