Best AI character swap tools in 2026 — 8 tools compared

The best AI character swap tools in 2026 are eroq Replace Pro, for putting your own characters into a clip with its moves, cuts, lip movement and original sound kept, up to four people at once; Viggle, for quick meme swaps; and Higgsfield, Runway, DomoAI and Akool for swaps inside larger studios. Wan Animate is the open model of the category: free weights with a replacement mode.

A character swap replaces a person in an existing video and keeps the rest: the motion, the camera, the scene, ideally the sound. It is not a face swap, which pastes a face onto each frame, nor motion transfer, which renders a new clip of your character doing the moves. Each section says which a tool does.

We make eroq, so it is on this list; everything said about the others is from their own public pages as of November 2026 — check their site before you decide.

1. eroq Replace Pro — your characters, up to four, sound kept

eroq Replace Pro is eroq's own Replace engine. Add a clip — an upload, one of your renders or a TikTok link — and @mention your characters in the order the people appear, left to right. Each wears their own outfit, the clip's or one you describe, or only the head changes. Every frame is rendered again at 24 fps in 768p or HD 1080p, and the moves, lip movement, camera, scene and original sound stay. A prompt can be as plain as "@Mira takes the dancer on the left, @Jun the one on the right; same moves, same cuts".

Every shot splits a whole TikTok, up to a minute, at its own cuts into renders of up to 10 seconds, leaves the shots with nobody to replace untouched, and reassembles them over the original sound. Trend templates: the Migos Hotel Lobby for two, the Bulin 47 freestyle for one.

Best at: the same face in every swap. A Character built from one to nine photos you have the rights to, a description or traits gets an identity sheet that holds the face through cuts and head turns. The full walkthrough covers photos, clips and fixes; the API is POST /v1/videos/edits.

Policy and privacy: uncensored within a written policy: fiction only; nothing involving minors, no real identifiable people without consent, nothing illegal. Made for your own original characters, 18 or older, or yourself — never a real person who has not agreed. Clips and characters stay private.

Falls short: one render is 2 to 10 seconds, so longer clips go shot by shot. Links are TikTok only; Instagram and YouTube are coming. The clip's voice stays the original, with no lip-sync tool for new lines, and no real-time swap. No free swap: the 40 welcome credits pay for an identity sheet, not a render.

Pricing: 30 credits / second in 768p — 300 credits for 10 seconds, 600 in HD 1080p — plus an identity sheet per character, paid once. Prices show before you click, failed renders refund themselves, credits never expire; packs from $10 for 1,000 credits (pricing).

2. Viggle — quick meme swaps, solo or in a group

Viggle runs on its own JST-2 model: Mix swaps a single character into a clip, Multi-Editor swaps several, Live swaps in real time.

Best at: a meme in minutes, and swaps in real time.

Policy and privacy: its community rules restrict content (no gore, among others), forbid using anyone's photo — friends and family included — without consent, and ask you to avoid political figures.

Falls short: Mix videos made with free credits carry a watermark; monthly plan credits expire on the billing date.

Pricing: free daily credits, one generation at a time. Pro is $7.99 a month for 80 credits plus 5 a day, Live $15.99 for 200, Max $63.99 for 800. Its alternatives have their own list.

3. Higgsfield — Recast and Genjutsu Object Swap

Recast replaces a character in a video from "a clear photo of the character", aiming to "integrate the entire persona including body and motion consistency". Genjutsu's Object Swap changes a chosen character, outfit, product or location and leaves the rest alone, on clips of 4 to 30 seconds with up to 30 reference images.

Best at: a swap and a full rebuild in one suite.

Policy and privacy: Recast's page cites "strict policies against any form of non-consensual or harmful content generation"; commercial use comes with paid Pro plans.

Falls short: Genjutsu's help article mentions no link import: you upload the clip.

Pricing: Recast starts free on daily credits; plans change often — check their site. See eroq vs Higgsfield.

4. Wan Animate — the open model with a replacement mode

Wan2.2-Animate-14B, from Alibaba's Wan team (September 2025, Apache 2.0), takes a video and a character image: replacement mode puts the character in place of the person, animation mode makes the image mimic the video's motion. Wan-Animate-2 followed in August 2026, weights on Hugging Face.

Best at: owning the pipeline, no fee per clip; Replicate and Scenario host it too.

Falls short: replacement needs preprocessed pose, face, background and mask videos, and Wan-Animate-2's default setup targets eight data-centre GPUs for 720p.

Pricing: the weights are free; the GPU or the host is not.

5. Runway — Aleph 2.0 for filmed footage

Runway's Edit Studio runs on Aleph 2.0: describe the change — its prompting guide covers "replace" edits — and the rest of the scene stays, in clips up to 30 seconds at 1080p, across cuts. Runway's Act-Two drives a character with an actor's performance.

Best at: a subject swap in footage you shot.

Falls short: Aleph 2.0 is 140 credits per 5 seconds, so Standard's 625 monthly credits make about four edits.

Pricing: Standard $15 a month ($12 billed annually), Pro $35 ($28) for 2,250 credits. See eroq vs Runway.

6. Kling Motion Control — transfer, not a swap

Motion Control takes a still character image and a reference video, and Kling "will replicate the movement, facial expressions, and details". Bind Face Subject adds photos to hold the face.

Falls short: "Motion Control currently supports one primary subject", and the reference audio is not transferred.

Pricing: inside the app — check their site.

7. DomoAI — whole body, up to 30 seconds

DomoAI's swap "keeps the movement exactly: whole body, not just the face", on Seedance 2.0 (up to 15 seconds) or its own model (up to 30); Subject Only keeps the background.

Falls short: 20- and 30-second swaps need Pro or Team.

Pricing: a free plan with starter credits; Basic $9 a month billed annually for 600 credits, Standard $29 for 2,200, commercial rights on paid plans.

8. Akool — swaps for marketing teams

Akool's AI Swap Studio has Face, Character, Head, Motion, Hair and Clothing Swap; Character Swap promises to "swap a person in your video with any character, real or generated".

Policy and privacy: whose face you may use is set by Akool's Trust and Safety page and content moderation policy — read them before you upload anyone.

Falls short: the free plan exports in 720p with a full-screen watermark; the API starts at Pro Max.

Pricing: Starter $12 per seat a month billed yearly for 200 credits, Pro $30 ($21 billed yearly) for 600.

What a good swap keeps

• The motion and the mouth: every step and syllable on the same frame.
• The cuts: the face has to survive each angle change — on eroq, the identity sheet's job.
• Everyone else: Replace Pro recasts up to four people, Viggle's Multi-Editor several, Kling one.
• The sound: Replace Pro keeps the original audio; Kling does not carry the reference's.

FAQ

What is the best AI character swap tool in 2026?

eroq Replace Pro for your own characters with the clip's motion, cuts and sound kept, up to four people; Viggle for a quick meme; Runway's Aleph 2.0 for filmed footage; DomoAI for long whole-body swaps; Wan Animate for an open model.

What is the difference between a face swap and a character swap?

A face swap pastes a new face onto each frame and keeps the body and clothes. A character swap renders the whole person again inside the original motion, camera and scene. Akool sells the two as separate modes; eroq Replace Pro renders the whole person, or only the head.

Is there a free AI character swap?

Not without limits. Viggle's free daily credits make watermarked Mix videos, Higgsfield's Recast starts on daily credits, DomoAI has a free plan, Akool's exports in 720p with a watermark. On eroq the 40 welcome credits cover an identity sheet; the swap takes a pack or a plan.

Can I swap a real person or a celebrity into a video?

Not without their consent. Viggle's rules forbid using anyone's photo without permission, Higgsfield cites policies against non-consensual content, and eroq allows only original characters, 18 or older, or yourself.

Can I swap characters in a TikTok video?

On eroq, paste the TikTok link in Replace: Every shot recasts the whole clip on its own cuts over the original sound. Instagram Reels and YouTube Shorts links are coming; until then, save the clip and upload it.

Your own character in a 5-second window is the fastest test: Replace shows the price before you click.
