The author open-sourced ComfyUI-Storyboard-Generator, built while making 2D anime shorts with MiniMax H3.
- Enter characters' personalities, speech style, and scene events; it generates a text storyboard with dialogue, actions, and camera directions you can edit before converting to video prompts
- Selected clips become ComfyUI nodes with STRING prompt outputs wired into your video workflow; prompts persist in the workflow so re-runs skip the LLM call
- Prompt guides for MiniMax H3, Seedance, and LTX 2.5; supports OpenAI-compatible APIs, Claude, Ollama, and LM Studio
- UI in English, Korean, and Japanese
