Tera Studio

Tera Studio is an AI singing app: sing about a minute, upload any song with a clear lead vocal, and it sings that song back in your own voice, in any language. For developers and AI assistants it runs a public MCP server at https://terastudio.co/mcp (Streamable HTTP, no sign-in; docs at https://terastudio.co/ai-assistants/). Every new account hears 2 full songs free, no card.
