How to use Oniichan?

Start by describing your manga story concept or idea. Oniichan generates a structured outline with scenes, character descriptions, and a world bible. Review and edit the outline, then generate full manga pages with consistent characters across every panel. After generation, edit any page, panel, or character individually using AI-powered inpainting and region edits. Save characters to your library to reuse across projects. Share your finished manga publicly or present pages one at a time.
