Open Source HTML Tool: Visually Build Complex MiniMax H3 Prompts

Brad12d3 · reddit · 2026-08-09

To simplify the complex reference workflows of MiniMax H3, a developer created a fully local, offline HTML prompt editor. Instead of manually writing tedious structured formats, users can define characters, environments, camera movements, and action beats via a UI. The tool automatically converts these inputs into the official structured prompt format required by H3. It also includes a built-in prompt checker to detect reference conflicts, timing issues, and inactive audio references.
