Tavus (CVI)

Tavus built its Conversational Video Interface (CVI) specifically for realtime, back-and-forth video conversation with an AI avatar — this is the category leader for "talk to a video AI face and have it respond naturally," not for generating pre-recorded clips. You give it a persona and connect it to an LLM; it handles the low-latency video generation so the avatar listens, thinks, and replies on camera with normal conversational timing. Growth-tier plans support many concurrent sessions, which matters if you are building something like a virtual tutor or interviewer that many students talk to at once. Free tier (25 min) is enough to feel the difference between this and a pre-recorded HeyGen clip. Worth mentioning: Simli is a much cheaper realtime alternative (~$0.009/min) for teams that want the interactive pattern without Tavus's price tag, at some cost in polish.
