Prelulu Launches Real-Time Video Calls for AI Companions

KEY FACTS

Tavus's Griffin-Lite is a full-duplex audiovisual AI model, currently limited to select early testers.
Prelulu is a consumer-facing AI companion app supporting text, voice, and video calls for some characters.
Prelulu users can interrupt mid-call, switch between text and voice, and retain relationship context for the same character.
Prelulu publishes its subscription tiers and call credit pricing in-app, while the Griffin page lists no dedicated pricing.
Tavus claims Griffin-Lite passes a real-time video Turing test, with 48% of participants mistaking it for a human on the call.

PHYSIX OBSERVATION

Tavus keeps its full-duplex audiovisual model locked in the lab, while Prelulu sells a comparable experience directly to people who want to chat. This exposes a signal: real-time digital humans are moving from developer tools to consumer subscriptions, and whoever gets users on board first and lays out pricing clearly will be first to capture relationship data and retention. Safety and compute costs will be the next threshold.
