Lacuna is a browser-based AI music studio that turns prompts, lyrics, audio, images, and PDFs into usable music assets. It can generate full songs with vocals, produce editable MIDI files, help write and refine lyrics, transcribe sheet music into MIDI, and clean phone photos into scanner-quality sheet music images. The platform is designed for fast music ideation, arrangement, and transcription without installing software. Its Music DNA controls let users fine-tune style, mood, BPM, and vocal type, while export-ready outputs support DAW workflows and commercial use.
