The best apps to put yourself in a video in 2026
SynthGen AI, Viggle AI, Kling AI, Reface and AI dance template apps compared: how each one works, who it is for, and where each falls short.
We make SynthGen AI, so weigh our opinion accordingly. We have tried to be fair: every fact about other apps below comes from their own website or App Store listing, checked on October 27, 2026, and linked at the end.
“Put yourself in a video” covers several different products. Some swap only your face into a template. Some animate your photo with moves from a library. A few can take any video you choose and rebuild the whole person as you. Knowing which kind you need narrows the list fast.

- What changes: only the face, or the whole person
- Platforms: iPhone, Android, web

1. SynthGen AI: best for remaking a video you just saw
SynthGen AI does one job. You share a video from TikTok, Instagram or YouTube to the app (or paste a link, or pick one from Photos), add one photo of yourself, and get the same video back starring you. It offers two modes: Swap me in keeps the original scene and replaces the person, Copy the moves animates your own photo with the original’s moves.
Strengths
- Starts from the video in your feed, not from a template menu
- Whole person replacement, not just a face
- No watermark, original sound kept
- Notification when the video is ready, usually in 3 to 6 minutes
Limits
- iPhone only
- No free tier: it needs a SynthGen Pro plan with monthly credits
- One person per video, clips of 3 to 30 seconds
2. Viggle AI: best free option and best for groups
Viggle is the best known name in this space. Its Mix feature combines one photo with one video to put you in the scene, and it has a large library of meme and dance templates. It also offers Move to animate a still image, a multi-character editor, and a real-time webcam mode.
Strengths
- A free tier (five videos a day at the time of writing)
- Web, iPhone and Android apps
- Templates, plus a multi-character editor for duets and groups
Limits
- Free videos carry a watermark and have shorter upload limits
- You upload a video file. We found no documented way to start from a TikTok or Instagram link.

3. Kling AI: best for full control
Kling is a complete AI video studio from Kuaishou, with text to video, image to video and more. Its Motion Control feature takes a character image and a reference video of 3 to 30 seconds in one continuous shot, and animates the character with that motion. SynthGen AI’s Copy the moves mode runs the same Kling motion control model.
Strengths
- Choice of model versions and quality levels
- Many other AI video tools in the same app
- Web, iPhone and Android
Limits
- More settings to learn, and credits priced per second that vary by version and quality
- You prepare and upload the reference video yourself
- No equivalent of Swap me in that keeps the original scene

4. Reface: best for quick face swaps
Reface made face swap mainstream. Today the app focuses on photo face swap, hairstyle try-on, AI avatars and headshots, and still lets you put your face into trending clips from its collection.
Strengths
- Very fast, very simple
- Huge range of photo effects beyond video
Limits
- Swaps the face, not the whole person
- Built around its own template collection rather than the video you found
- Rated 16+ on the App Store

5. AI dance template apps: best for picking a dance from a menu
A group of apps turns one photo into a dancing video from a library of preset dances. Dance AI (by Deepix AI) works from one photo and a dance style picked from its library. Photo Dance (by SPARKHUB) offers hundreds of dance templates and lets you upload your own dance video as a template.
Strengths
- Simple when you just want any dance, fast
- Lots of preset styles
Limits
- Limited to their libraries, or to videos you upload yourself
- Many use weekly subscriptions
