Swapface

Face swap tools usually make you upload a clip, wait for processing, then download the result. Swapface skips that wait.

It is a real-time AI face swap app that turns you into someone else from a single photo, with no processing time, so the swap shows up while you are on camera.

That makes it a fit for live streaming as well as recorded content creation.

You pick one reference photo, and the swap runs live.

The app is listed under image generation and editing, but its range is wider than that: it also covers AI face swap video, AI lip sync, AI avatar generation and AI voice cloning, so a streamer or video creator can change both how they look and how they sound.

Swapface describes itself as light and easy to set up, which matters for live use where a heavy app can slow things down.

Those are the maker's claims, so test the realism on your own webcam and hardware before you build a stream around it.
