Free AI Music Assistant — Weekly Co-Writing Included
Talking to it is included. Only the rendering costs credits.
Weekly co-writing allowance included · pay only for output
Free AI Music Assistant
Voxmin AI Studio is a conversational music assistant: it writes lyrics, shapes production prompts, and can drive karaoke or lyric-video jobs from a YouTube link. The co-writing itself comes with a weekly allowance included in your account, so brainstorming, drafting, and rewriting do not each cost money. Credits are only spent when you ask it to actually generate or process something, and that cost is shown before it starts.

What it costs
Weekly co-writing allowance included · pay only for output
| Item | Price | Detail |
|---|---|---|
| Co-writing conversation | Weekly allowance included | Lyric drafting, rewriting, and prompt shaping without spending credits per message. |
| Generating a song | 7–45 credits | Same price as Song Studio — quality level decides the cost. |
| Karaoke or lyric-video jobs | 30–60 credits | Driven from the same conversation, priced per job. |
| Subscription | None | The allowance is part of your account, not a plan you pay for monthly. |
Why the writing is included and the rendering is not
Writing lyrics is cheap to run and it is where most of the creative work happens, so charging per message would just make you write less and produce worse songs. Rendering audio is genuinely expensive compute. Splitting it this way means the iteration you should be doing freely is free, and the part with a real cost behind it is the part you pay for.

Frequently asked questions
AI Studio includes a weekly co-writing allowance with your account, so conversation, lyric writing, and prompt shaping do not spend credits per message. Generating songs or running karaoke and lyric-video jobs costs credits, shown before each job starts.
No. Song Studio, AI Studio, and My Voice Studio all use the same account and the same credit balance. There are no per-studio plans.
It is a weekly allowance, so it comes back. Paid generation jobs are separate and always show their credit cost before running.
