These tools solve different problems. Kits.ai is a hosted studio built around licensed artist voices and in-browser conversion, which is genuinely useful if you want a cleared voice to sing on your track. NiceVois does not offer a voice library at all — it trains a model from audio you supply and hands you the files.
The question worth asking is whether you need a voice to use, or a model to own. Those lead to different products.

Before you pay
Do I need an account to pay?
No. Pay with any email. Sign in with that same email on any device and everything you paid for is there.
What does unlimited actually mean?
No minutes to count on any tool, every output included, up to 500 epochs per training run. Fair use applies.
How do I cancel?
One click from your account, no email needed. You keep everything until the end of the month you paid for.
What if a training fails?
You are not charged for it. A failed or cancelled run releases what it reserved, and an upload that never arrives does not spend your free run.
Who sees my card?
Lemon Squeezy, the merchant of record. NiceVois never sees card details, and tax is handled at checkout.
Do I keep my voices if I leave?
Yes. Every model is a .pth, .index and ZIP you download, and they work anywhere RVC runs.
What happens to my audio?
It is processed for your job and never shared. Source audio is removed after validation. Models trained on a paid run stay until you delete them; a model from the free run is kept for 7 days, and its expiry date is shown on the model itself.
Can I hear it before I pay?
Yes. Your first training is free, and every finished model comes with a listening proof before you decide anything.
Wrong charge or an unused month? Email info@nicevois.com with the checkout email and date; it is reviewed with Lemon Squeezy and returned to the original payment method. Refund policy · Privacy

Persistent cloud storage
Your model library
Your voice models are files you own. Download them once and no platform can take them away.

Paid model packages stay saved until you delete them.
Your .pth, .index, ZIP, and private listening preview remain available after closing the browser or restarting your computer. A model from the free training run is kept for 7 days and shows its expiry date; download it before then. Full-resolution source audio and temporary training files are removed after validation.

Why portability is the real difference
A hosted voice works inside the platform that hosts it. A downloaded .pth and .index work in any compatible RVC interface, on your own machine, indefinitely. That distinction stopped being theoretical in 2026, when a large hosted model catalogue closed and took its models with it. People who had exported files kept working; people who had not, did not.
What we do not provide: no voice catalogue, no licensed artist voices, no in-browser cover creation, and no rights clearance. If your project needs a commercially cleared voice, a licensing platform is the correct tool and this is not a substitute for it.
What you need to bring
A clean, single-speaker recording of a voice you own or have clear permission to train, in WAV, MP3, FLAC, M4A, or OGG. Your first training is free, and every job is quoted before it starts. The dataset guide covers what makes a recording usable.
Permission is the boundary
Because we do not supply voices, the rights question sits with you. Train your own voice or one you have explicit permission to use. Our acceptable use policy is specific about this.
Need the model, not the library?
Upload permitted audio and download a portable .pth, .index, and complete ZIP.
