What it does
A voice conversion tool with a browser-based interface: train a voice model, then re-voice singing or speech with it. Google Colab notebooks are provided if you would rather not set up locally; running it on your own machine needs Python, the command line and a GPU for reasonable speed. The maintainers have stated the project will no longer receive frequent updates, focusing instead on security and dependency fixes. Cloning someone else's voice without their consent raises serious legal and ethical problems - use it on your own voice or one you have permission for.

- You install it like a normal desktop app. No command line involved.
- Does Applio work on a phone?
- No. It needs a computer.
