Melokai is an AI-powered osu! beatmap generator and mapping companion that creates playable structural beatmap drafts from music files. Users can upload MP3, WAV, or OGG audio, select a target difficulty and pattern style, and generate hit objects based on the track’s rhythmic structure. The tool is designed to assist with beatmap creation by handling timing analysis, snapping, flow suggestions, and object placement while leaving room for creative editing and refinement.

Melokai supports pattern styles such as streams, jumps, tech, and alternate patterns. Mapping parameters including Circle Size, Approach Rate, Overall Difficulty, and HP Drain can be adjusted independently or balanced toward a target star rating. Generated maps can be exported as ready-to-play .osz files containing hit objects, timing points, audio, and metadata for use with the osu! client.

The app also supports video backgrounds by extracting audio from a music video and preserving the original video as the map background. Melokai is intended for osu! players, beatmap creators, and beginners seeking an automated starting point for rhythm game mapping and iterative map development.
