Face Swap Video App
for iPhone and Android

How the AI face swap video generator works

Everything happens inside the app, in three steps. There is no timeline, no masking and nothing to learn.

1. 1Add a short clipChoose a video of one person, up to 20 seconds long. The movement, expressions and framing in it are what your character will follow.
2. 2Add a characterAdd a photo you own or have permission to use. No photo? Describe a character in words and ActLike AI creates an original one.
3. 3Pick a quality and generateCredit Saver 480p for quick ideas or Best Quality 720p HD for the final cut. Your video is ready in minutes and saves to Photos.

What the AI actually does to your clip

Inside an AI face swap video generator, the work breaks down into a few stages. Knowing them makes it obvious why some inputs work better than others.

1. Following the motion

First, the model tracks the person in your clip frame by frame: where the head turns, when they blink, how their expression changes. That motion is what your character inherits.

2. Building the character

Next, it reads your photo, or your written description, and rebuilds that character onto the tracked motion, rather than pasting a still image on top of the video.

3. Matching the scene

With Scene Match switched on, the app fits the character to the lighting and mood of the original clip. This is the step that makes a result read as footage instead of a filter, and it costs 1 credit per video.

4. Exporting the video

Finally, the video is exported at 480p or 720p HD. Every creation stays in your History, and you can save it to Photos or share it straight to other apps.

What people make with it

ActLike AI is built for short, original, creative video. These are the most common reasons people open it.

Why an app instead of desktop editing

Traditional face replacement means rotoscoping, masks and long exports. Here is how the two approaches compare.

Desktop software still wins when you need frame-by-frame control or multi-person shots. The alternatives comparison covers where each kind of tool fits.

Six habits that produce a clean result

An AI face swap video generator does the heavy lifting, but your inputs still decide the outcome.

• Use a bright, front-facing photo. Even daylight beats dramatic shadow, because the model can read every feature.
• Keep clips short. Five to ten seconds costs fewer credits and holds attention better on social feeds.
• Pick footage with one clear person. ActLike AI is designed for clips of a single subject.
• Avoid anything crossing the face. Hands, microphones and hair over the mouth all reduce accuracy.
• Turn Scene Match on for anything you share. It costs one credit and makes the biggest visible difference.
• Draft at 480p, finish at 720p. Test the idea cheaply, then remake the winner in HD.

Credits, pricing and what a video costs

Pricing is per second of video, paid with one-time credit packs bought inside the app.

Credit Saver 480p uses 1 credit per second and Best Quality 720p uses 2. Scene Match adds 1 credit, and describing a character instead of using a photo uses that same credit. A typical 10-second video at 480p with a photo therefore uses about 10 credits, and the same video at 720p with Scene Match uses 21.

US App Store packs range from 5 credits for $1.99 to 500 credits for $49.99, and nothing renews. If a generation fails, its credits return to your balance automatically. Every pack is listed on the pricing page.

Using face swap technology responsibly

Any AI face swap video generator needs clear rules, so here they are in plain language.

Only use videos and photos you own or have permission to use, and never use the app to deceive, impersonate or harass anyone. Several platforms and regions also require you to label synthetic media featuring a real person, so use the AI label wherever it is offered.
