❓ FAQ: AI Avatar Video Apps (2026)

A: Yes. All three platforms allow you to clone your own voice or choose from hundreds of premium AI voices. You can even upload an audio file for the avatar to lip-sync to.
Q: Are these apps free?
A: Most offer a free trial with limited minutes (usually 1–5 minutes of video). For serious use, subscriptions start around $30/month.
