A realtime face-swap model can produce an impressive transformation and still leave users unsure how to begin or what the product actually controls.
That is why we present Vivify Live Face Swap preview as a browser product rather than another isolated model demo. For AI product teams, the lesson is simple: setup, feedback, and honest boundaries matter as much as the output.

A model is not the whole product
A demo proves that a model can transform a live stream. A usable product must also make the first session obvious and give the user enough context to judge the result.
Make the first session obvious
Vivify starts with a reference face already selected. Keep it, choose another preset, or upload an authorized face. Then sign in if needed, click **Start live preview**, and grant camera permission when asked. The separate camera-preview button is optional.
Try the flow in [Vivify Realtime Face Swap](https://vivify.video/realtime-face-swap). The principle is simple: keep required decisions visible without turning optional controls into extra steps.
Show the comparison and the boundary
Vivify keeps the original camera feed beside the AI result. That makes it easier to see how the transformation responds while the user moves, instead of judging an isolated output.
The product controls reference setup, camera flow, session states, and presentation. The underlying model largely shapes pose, expression, occlusion, and motion behavior. The current browser experience is for live viewing and comparison—not recording, download, virtual-camera output, or production livestreaming.
Use only a self-owned or authorized reference, and disclose realistic synthetic media when sharing it. A useful AI product should make it clear how to start, what the user is seeing, and what the experience is designed to do.
