Loading
1 · Prepare a dataset

Open the Dataset Web UI (Mac / Windows), load your recordings, and it slices them into clean clips and exports a ready-to-train dataset.

2 · Train a model

Train locally with the trainer for Mac (Apple Silicon) or Windows (NVIDIA CUDA), or on a free cloud GPU with the Colab & Kaggle notebooks.

3 · Use it live

In the voice changer, choose Upload Custom Model and pick your model's ZIP. Press the power button, pick the voice, and select the virtual microphone (BlackHole on Mac, VB-CABLE on Windows) in your call app.
