Clavet vs Lacuna

Clavet is a web-based songwriting workspace from Crescender in Melbourne, Australia. It brings lyrics, melodies, voice notes, and song drafts into one place, with audio recording that automatically transcribes musical ideas into text. An AI assistant can suggest ideas, generate prompts, rewrite lyrics, and organize work; Crescender says user work is not used to train AI models. Song tools include version history, structure controls, a searchable library, and exports to PDF, DOCX, and plain text. Co-writers can be invited to share lyrics and snippets, record ownership splits, and maintain an audit trail. The maker says timestamped cryptographic authorship proof is provided under Australian copyright law. Songs connect to the Crescender repertoire for setlists and rehearsal plans, with shared sign-in. Clavet is described as offline-friendly and syncs after reconnection. Every feature and unlimited songwriting are included in the free, ad-supported plan.

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.
