The workflow

Your performance, a different voice

You bring the take. Kits handles the transformation — no studio session, no hired vocalist.

STEP 01

Record or upload

Sing or speak your part, or drop in an existing vocal. You can also train a custom model from your own files or a video.

STEP 02

Pick a voice

Choose from 100+ officially licensed and royalty-free models, design a custom voice, or blend two into a new hybrid.

STEP 03

Convert & finish

Kits VC transforms the take into the chosen voice. Then clean it with vocal remover, stems, harmonizer and AI mastering.

Why it's different

Licensed voices, with the artist's consent — not scraped

Most AI voice tools either generate from scratch or clone whatever they can find. Kits' core is voice-to-voice conversion through its flagship Kits VC model, and crucially its artist library is built by partnering directly with creators to formally authorize each model — consent-based, not scraped. Honest framing: generating a brand-new voice purely from lyrics isn't its strength; this is a conversion toolkit for people already making music, not a prompt-to-song app.

The toolset

A full vocal workflow, not one trick

Conversion is the core; the rest finishes the track.

Voice-to-voice conversion

The flagship Kits VC model transforms your take into 100+ officially licensed, royalty-free voices — or a custom model trained from your own files or a video. This is the heart of the platform.

Voice Designer

Craft a custom voice with breath, power and warmth controls.

Voice Blender

Combine two voices into a brand-new hybrid vocalist.

AI instruments

Hum a melody and get realistic guitar, bass or sax.

Vocal remover & stems

De-echo, de-reverb and split vocals, drums, bass and other.

Mastering, harmonizer, TTS & API

One-click AI mastering, a harmonizer, text-to-speech in 12+ languages, plus a public API and an artist program to publish models and earn.

Where Kits AI wins — and where it doesn't

It's a conversion specialist with a licensing ethic. Compared on what decides it:

From users

What people actually say

★★★★★

It delivers on voice conversion without the usual AI hype — clean results on well-produced tracks, and I like that the artist voices are actually licensed.

Producer
Conversion quality
★★★★★

Training a model on my own vocals and being able to publish it for passive income is a genuinely different idea from every other tool.

Vocalist
Artist program
★★★☆☆

Great at conversion, but it's niche — if you're not making music it's overkill, the harmonizer is very autotune-y, and TTS is behind premium.

The backstory

A voice-conversion specialist that put artist consent first

Kits AI is a studio-quality AI voice toolkit built specifically for musicians and producers, running in the browser. Its research arm, Kits Research, develops the flagship voice-conversion model, Kits VC. The official site is kits.ai.

The defining choice is ethical, not just technical: rather than scraping voices, Kits partners directly with artists to formally authorize each model, and lets voice owners publish models and earn passive income when others use them. Around that sit conversion, Voice Designer, Voice Blender, an AI instrument library, vocal remover, stem splitter and AI mastering.

Be clear about scope. This is a conversion toolkit for people already making music — strong at voice-to-voice, weaker at generating a brand-new voice purely from lyrics, which is a different product category. If you don't work with audio, it will feel too specialised.

The honest caveats: text-to-speech is gated behind premium, the Harmonizer leans heavily autotuned, vocal removal isn't perfect on dense mixes, and there's a mild learning curve that assumes basic DAW and audio knowledge. Treat the free trial as evaluation, and check licence terms per voice before commercial release.

Frequently asked questions

What is Kits AI?

Kits AI is a studio-quality AI voice toolkit built specifically for musicians and producers. Its core is voice-to-voice conversion: you record or upload a vocal and transform it into another voice, choosing from 100+ officially licensed, royalty-free artist models or a voice you train yourself. It is not a text-to-song generator.

How is Kits AI different from other AI voice tools?

Two things stand out. First, Kits partners directly with artists to formally authorize voice models, so the licensed library is consent-based rather than scraped. Second, its focus and reputation are in voice-to-voice conversion via the flagship Kits VC model — generating a voice from scratch out of lyrics is not its strength; tools built for that can do it better.

Is audio from Kits AI royalty-free?

Kits states its licensed and library voices are royalty-free and usable in your content, and it partners with artists to authorize models. As always, review the current licence terms for the specific voice and your use case before releasing commercial music, since terms can differ between official artist models and the royalty-free library.

Can I train my own voice on Kits AI?

Yes. You can train a custom AI voice model from your own audio files or from a video, then convert into it. There is also a Voice Designer to craft a voice from breath, power and warmth parameters, and a Voice Blender to combine two voices into a new hybrid.

Is Kits AI free?

There is a free trial with no credit card so you can test voice conversion. Text-to-speech and parts of the toolset sit behind paid tiers, and heavier use needs a subscription. Treat the free trial as evaluation rather than an ongoing free plan.

Do I need music experience to use Kits AI?

Some helps. Kits AI is a specialised music tool — the interface is approachable, but understanding key, tempo, audio formats and basic DAW workflow improves results. If you do not work with music or audio, it may feel too specialised compared with a general voice app.

What are the limitations of Kits AI?

It is a niche, music-focused toolkit, not a general or text-to-song tool. Text-to-speech is gated behind premium, the Harmonizer can sound autotuned, vocal removal is not perfect on dense mixes, and generating a brand-new voice from lyrics is weaker than its core voice-to-voice conversion. Pick it for conversion quality and licensed voices, not for prompt-to-song.

Can I earn money with my own voice model?

Yes. Kits runs an artist program where you can create and publish a voice model and earn passive income when others use it, alongside a public API for developers who want to build on top of Kits audio models.

Who is behind Kits AI?

Kits AI is developed by Kits AI, with a research arm (Kits Research) advancing its flagship voice-conversion model, Kits VC. The official site is kits.ai. The company emphasises formal artist authorization for its voice models.
