In their own words
CAVN AI
CAVN AI is a music creation platform for generating songs, cloning voices, producing music videos, and refining tracks. Song generation accepts text, image, or video input. Production tools include stem separation, mastering, MIDI export, audio enhancement, and 12-track editing with local adjustments. Its video generator supports lip-sync and videos up to 10 minutes long at up to 4K resolution. Users can clone or replace voices and create an AI singer or virtual artist. The platform integrates Smodel, Mureka, Minimax, Ace Step, and its own CAVN model. Its API documents prompt-based song generation, result queries, stem splitting, and audio-to-MIDI tools, with agent integrations aimed at MCP, OpenClaw, WorkBuddy, Hermes-style memory agents, and enterprise automation. The Free plan costs nothing and includes 10 daily renewing credits, about four songs, and two concurrent generations. Free output is for lawful personal, non-commercial use with attribution, and generated songs are public by default. Basic costs $10 a month, billed annually at $120/year; Standard costs $30 a month, billed annually at $360/year. Paid subscribers receive commercial-use rights subject to the terms.
Lacuna
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.
