Best AI Character Swap Tools: Our Top Picks for 2026

Swapping a character used to mean a reshoot or frame by frame editing. Now you can upload a clip, add one image of the new character and let AI handle the replacement. Zoice is our top pick: you upload the video of the person to replace, add an image of the new character and click Generate, with no prompt to write.

This guide compares Zoice with Viggle, Magic Hour and DomoAI so you can pick the right tool for your clip. Each entry covers key features, who it suits, pros, cons, the G2 rating where one exists and how pricing works.

What Is AI Character Swap?

AI character swap replaces the person in an existing video with a new character taken from an image. The movement, timing and scene come from your clip, and the look of the character comes from the picture you add.

It suits creators who already have a clip they like and want a different character in it: a meme, a social post, a mascot in a trend video or a quick test of a new look. Some tools swap only the face, others replace the whole body, so check which one you need.
