What You Can Do

Once connected, just ask your AI assistant in natural language:

"Read this paragraph aloud using the podcast_conversational_female voice"

"Create a podcast dialogue between two speakers about AI"

"Clone my voice from this audio file"

"What voices are available?"

"Check my Leanvox balance"

The AI assistant handles everything — no code needed.
