Lacuna Overview

Lacuna is an AI music studio built around a conversational music agent: describe a track in plain language and the agent handles style, structure, vocals, and lyrics for you, or switch to a hands-on custom form for direct control. The AI Song Generator turns lyrics, text, or sheet music into finished songs with vocals across several song models, while the AI Lyrics Generator drafts and refines lyrics from a prompt or a genre template. Beyond generation it covers word-level synced lyrics, lyric-video export, mastering, stem separation, album-cover art, MIDI tools, and sheet-music conversion. Paid plans add a commercial license with full copyright. Available in 9 languages, with an open-source SDK, CLI, and MCP server for developers.
