Free AI Video Editor: Replace a Person in Your Video
Replace a person in your video
Upload your clip, then add one photo of the new character. The whole person is swapped and every move stays as filmed.
What can this AI video editor do?
LazyKiwi's AI video editor is a set of browser tools for the edits that are slow by hand. Start with Character Swap: upload a clip and one photo, and the whole person in the video becomes that character while the motion, timing and camera stay as filmed. The other tools remove objects, change the background, add subtitles or text, enhance, restyle, stabilize or flip a clip. It is free to try, and every run shows its price before anything is charged.

How to replace a person in a video in 3 steps
Two uploads and a click. No masks, no keyframes.
Step 1
Upload your clip
Any clip with a person in it, from your phone, a camera or a screen recording.
Step 2
Add one photo of the character
A mascot, an illustrated hero or a real person you have permission to use. Front-facing works best.

Download the swapped video
The whole person is replaced while the moves and the camera stay as filmed. Then run another edit on it if you like: captions, text, stabilize.
