Two writing modes
Prompt mode turns a short description into lyrics, melody, and arrangement at once. Custom mode takes your exact words and builds the song around them, section by section.
Brief the song, set the boundaries, and compare full-length takes against the same idea.
prompt in, produced song out
Describe the track once, set the boundaries that matter, and get full-length takes you can compare against the same brief.
Unconstrained generation optimizes for pleasant and average. The controls here exist to pull the output toward your specific intent: exclusion fields keep unwanted styles out of the mix, custom mode lets your lyric sheet drive the structure, and model choice trades speed against vocal realism.
The result panel keeps every take next to its exact settings. When something sounds right, you can see precisely which brief produced it — and when something misses, you know which instruction to sharpen rather than guessing from scratch.

This generator is built for people who care which take wins. Start from a one-line prompt or bring finished lyrics, then decide what stays fixed: the model, the genre blend, the vocal gender, the duration, and the styles the song must avoid. Every setting you pin down turns the next generation from a lottery ticket into an experiment.
Each run produces paired takes, so you always hear two answers to the same question. Keep the stronger one, adjust a single instruction, and run again — that loop is how a decent idea becomes a song you actually release.
Prompt mode turns a short description into lyrics, melody, and arrangement at once. Custom mode takes your exact words and builds the song around them, section by section.
Stack genre, mood, and instrument tags to point the model, and list what must not appear — no EDM drop, no autotune, no spoken intro — to fence off the failure modes you already know.
Switch between generation models for different vocal characters and rendering speed. The same brief on two models is often the quickest way to find the sound you meant.

Treat the generator like a session player who follows instructions literally. Precise briefs get precise performances.
Decide before generating: language, rough tempo feel, vocal type, and the one emotion the chorus must deliver. Put those in the brief explicitly.
Generate one pair, play both takes fully, and mark the moments that work — a chorus melody, a drum feel, a vocal tone worth keeping.
Rewrite only the instruction connected to what missed. Three focused runs beat ten shotgun attempts, and cost a fraction of the credits.
Paste a finished lyric sheet, mark the chorus, and hear it sung in the style you intend to pitch — a demo for collaborators in one sitting.
Instrumental mode with tight exclusions produces beds that stay out of the voice-over's way: no vocals, controlled energy, predictable length.
Run one hook brief across country, synthwave, and bossa nova to hear which setting carries the idea before committing production time.
"Starts sparse, builds to a wall of guitars by the second chorus" gives the model an arc. A pile of genre tags gives it a shrug.
Two or three precise negatives work; a paragraph of don'ts muddies the signal. Ban the specific thing that ruined the last take.
Louder takes sound better for the wrong reason. Level-match before choosing a winner, especially when judging mixes across models.
Prompt mode writes everything from your description — lyrics included. Custom mode preserves your lyric sheet word for word and generates the music around it, which is the right choice when the words are already the point.
Yes. Toggle instrumental mode and the generator skips vocals entirely, which also gives the arrangement more room for lead instruments — useful for scores, beds, and ambient work.
The same brief legitimately supports different musical answers. Paired takes let you hear two interpretations at once, and comparing them teaches you which parts of your brief are doing the steering.
Specific about feeling and function, economical about everything else. One vivid sentence about the scene plus two or three concrete constraints reliably outperforms a paragraph of adjectives.
Bring one idea and three constraints. Leave with a song that sounds like a decision, not an accident.
