Lacuna is an AI music generator that creates full songs from either lyrics or a text description, producing vocals across a range of genres.
Supply lyrics and it builds the music around them. Describe the song you have in mind instead and the AI generates a complete track with vocals, melody and instrumentation, parsing the emotion, style and rhythm out of your description.
Around the generator sits a set of working tools. An AI MIDI generator produces playable MIDI from a text prompt, a MIDI editor handles composing and editing, and a sheet music scanner turns photographs into scanner-quality sheet music.
The lyrics studio is built for people who care about craft: real-time syllable counting for rhythm control, automatic end-rhyme detection, and AI-assisted co-writing for continuing a verse, rewriting a line, or suggesting rhyming alternatives.
Music DNA exposes the professional parameters the AI generated, so they can be fine-tuned at any point rather than accepted as given. A collection of AI-generated samples across styles is available for reference. Plans start at $19 per month.
