Lacuna
Freemium
Create, edit, and enhance music with AI agents for composition, lyrics, MIDI, and live coding, then turn finished tracks into shareable visuals.

About
Lacuna makes music from text. You describe a mood or paste lyrics, and it gives you a full track with vocals and instruments. It sits in music generation work.
You can also clean up audio, pull apart stems, edit MIDI with plain words, and make shareable visuals. It runs in your browser.
The free tier lets you start without paying. Paid plans include rights to use the music in videos, podcasts, or games.
Open it if you need quick music or audio cleanup without learning heavy software. Skip it if you need pro-level mixing or live instrument recording.

How you use Lacuna
The path is short.
- Describe your track or paste lyrics you already have.
- Pick a mood, genre, or use a sound-design template.

- Open the lyrics editor to tweak words or get AI suggestions.
- Use Music DNA to adjust BPM, intensity, or style before you export.
Why you should ignore it
Skip it when the fit is wrong.
- Skip it if you need pro mixing: It is not a replacement for Logic or full multi-track control. You will hit walls on complex productions.
- Skip it if you want simple and clean: The interface can overwhelm. You get 100+ slides of tutorial and still feel lost.
- Skip it if you need guaranteed vocal quality: The AI vocals can sound generic on popular styles. You may need to regenerate multiple times.
- Skip it if you rely on .docx exports: This refers to a different Lacuna product for book formatting. The audio tool exports music files, not documents.
