We make SynthGen AI. Facts about Kling come from Kling’s own guide and App Store listing, checked on October 27, 2026.
This comparison is unusual, because SynthGen AI uses Kling. Our Copy the moves mode runs Kling’s motion control model. So the question is not which AI is better. It is which way of using it suits you.
Kling AI: the studio
Kling, from Kuaishou, is one of the leading AI video model families, and its app is a full studio. Motion Control is one tool among many: you provide a character image and a reference video of 3 to 30 seconds in one continuous shot, or pick a clip from the Motion Library, then choose a model version and quality level. The output matches the length of the reference.
If you enjoy tuning settings, comparing versions, and also want text to video or image to video in the same place, Kling is built for you.
SynthGen AI: the shortcut
SynthGen AI wraps that power into three taps. You share a video from TikTok, Instagram or YouTube, and the app fetches it, trims it to 30 seconds if needed, and prepares it for the model. You add your photo, choose a mode, and tap Make it me. A notification arrives when it is done.
The part Kling does not do: keeping the scene
Motion control animates your image, so your photo’s background becomes the scene. Often that is what you want. But for many trends the place is the point: the stage, the party, the street. For those, SynthGen AI has Swap me in, which runs a different model, Wan 2.2 Animate in replacement mode. It keeps the original video’s scene, light and camera, and replaces only the person with you.
Having both modes behind one button, at the same price per second, is the main reason to use SynthGen AI over going to the model directly.
Bottom line
Use Kling AI if you want control and a full toolbox. Use SynthGen AI if you want the same class of motion transfer with no setup, plus scene-keeping replacement, started from the video in your feed. Read more about the two modes in Swap me in vs Copy the moves.
