Lacuna is an online AI audio studio for musicians, songwriters and content creators. Use the AI Song Generator to create songs with vocals or instrumentals, or develop lyrics and song structure with the AI Lyrics Generator. Work from text prompts, lyrics, images, or supported melody inputs.

Continue with stem separation, vocal removal, audio cleanup, mixing and mastering. Turn finished tracks into lyric videos or music visualizers. The product supports multiple interface languages, including English and Chinese.

Registered users receive free monthly credits. Paid plans add more credits, audio downloads and applicable commercial-use rights. Availability, limits and entitlements are documented on the official pricing and license pages. Lacuna is operated by JOYLINK LTD.

• Text-to-song generation: Turn a short prompt, story, mood, or creative brief into a full song with AI-generated lyrics, vocals, melody, and instrumentation.
• Custom lyrics and vocal styles: Add your own lyrics, choose vocal or instrumental output, and adjust available voice and style settings to shape the result.
• Multiple AI music models: Choose between models designed for different needs, including creative flexibility, closer adherence to lyrics, and structured song generation.
• Song remixing and extension: Change the musical style or add new sections to an existing track without rebuilding the entire song.
• Section-level editing: Rewrite selected parts of a song, such as a verse or chorus, while keeping the rest of the track intact.
• Stem separation: Split tracks into separate vocal, drum, bass, and instrument files for further editing or mixing.
• AI mastering: Refine loudness, tone, and dynamics with genre presets or a reference track.
• Music analysis: View details such as BPM, key, chord progression, and loudness to help with editing and production.
• Song versions and visual workspace: Keep generations, edits, and alternate arrangements connected on one canvas, making it easier to compare ideas and return to earlier versions.
• Audio downloads and commercial licensing: Download finished tracks with a paid subscription. Commercial use is included in paid plans, while Pro and Ultra offer a downloadable commercial license document.

• Easy for beginners: Create songs from everyday language without needing to play an instrument or understand music production.
• More control after generation: Edit lyrics, remix styles, extend arrangements, and refine individual sections instead of accepting the first result.
• Several creative options: Generate and compare different musical directions to find a sound that suits your project.
• Useful production tools in one place: Stem separation, mastering, and track analysis reduce the need to switch between separate tools.
• Supports original lyrics: Songwriters can hear their own words set to a melody and vocal performance.
• Works for different music styles: Create music for personal projects, videos, podcasts, games, and other creative work.
• Free entry point: New users receive monthly credits to try the platform before paying for a subscription.

• Limited free credits: The free plan provides 120 credits per month, which limits how much music you can generate.
• Paid subscription required for downloads: Free users can create and listen to songs, but downloading audio requires a subscription.
• Results may need editing: Generated lyrics, vocals, and arrangements may not match your idea on the first attempt.
• Different models have different strengths: Vocal language support, lyric accuracy, and musical structure depend on the model selected.
• Commercial licence documents vary by plan: Paid plans include commercial use, but a downloadable licence certificate is included with Pro and Ultra, not Basic.

• Independent musicians: Turn early ideas into full song demos, test different arrangements, and prepare tracks for release without paying for a full studio session.
• Songwriters: Hear written lyrics sung with AI vocals, explore melodies, and refine individual verses or choruses before recording.
• Music producers: Generate reference tracks, separate instrument stems, compare arrangements, and use the audio as a starting point for further production.
• YouTubers and video creators: Create original background music, intros, outros, and soundtracks for videos without sourcing every track from a music library.
• Podcasters and streamers: Produce theme songs, transitions, and background tracks that fit a show's mood. Separate stems to adjust the music around spoken audio.
• Digital marketers: Make music for social media campaigns, product promotions, and advertisements using a paid plan with commercial-use rights.
• Independent artists releasing music: Generate songs, polish the mix with AI mastering, create cover art, and prepare audio for distribution or promotion.
• Beginners and hobbyists: Experiment with songwriting, genres, and vocal styles using plain-language prompts instead of learning music production software first.
• Game developers and multimedia creators: Develop song ideas, instrumental tracks, and musical themes for prototypes, indie games, and creative projects, subject to the relevant licensing terms.
