QUESTIONS
Frequently
asked.
When does AI load?
Only after you turn on an AI vocal mode. The public page never preloads the model.
What does Remote control?
Remote sends validated control values such as volume, pitch, vocal mode and video timing. It does not carry the audio stream.
Where are recordings stored?
Recordings and preferences are designed to stay in the local browser or Extension storage. You can play, download or delete your own takes.
Will every GPU perform the same?
No. Browser acceleration depends on the browser, driver, operating system and available hardware. NextSona exposes lighter options for constrained devices.
