Lacuna turns a short idea into song lyrics and can send them to its music generator to create a track with AI vocals. The editor supports line-by-line rewrites, syllable counts, automatic rhyme highlighting, and rhyme suggestions ranked by meaning. It supports nine languages, with phonetic rhyme support for English, Spanish, Chinese, Japanese, and Korean. Automatic snapshots let users restore an earlier take after AI edits. Lacuna describes the workspace for songwriters, rappers, topliners, producers, and first-time writers, and says generated or edited lyrics may be recorded, released, and used commercially. The free plan provides 120 credits per month without requiring a credit card; each lyrics AI use costs five credits, and unused credits do not roll over. Pricing lists paid service from $9.50/mo (annual), while Basic is $19 a month. Audio downloads require a subscription, and credit packs alone do not include them. The developer API requires Pro or Ultra and uses credit-based billing. Lacuna lists web, iOS, extension, and API platforms.
