Lately, everyone’s seeing those “photos with someone else’s face” or “videos where a still image moves” trending on social media—how are those even made? Do you need expensive software…?

What is Remaker AI? A Multi-Functional Creative Tool Accessible via Account Registration Only

Remaker AI is a cloud-based AI platform that can be used simply by accessing it from a web browser such as Google Chrome or Safari, without needing to install any special software or own a high-spec gaming PC (equipped with a GPU).

Its biggest feature is that “multiple powerful AI tools are consolidated into a single website.”
Normally, you would need to switch between different apps—this app for face swapping, that site for video generation… but Remaker AI handles everything in one stop.

List of Main Features Included

  1. Face Swap

    A feature that naturally replaces the face of a person in a photo or video with another designated face. It supports both still images and videos.
  2. Image to Video

    A feature where AI predicts motion and changes based on a single still image to generate a short movie. “Live Portrait” and similar tools are also included here.
  3. AI Image Upscaler

    A feature that enhances and enlarges low-resolution images or blurry photos while restoring details.
  4. Background Remover

    A feature that instantly recognizes subjects such as people, products, or animals and makes the background transparent in a split second.
  5. AI Photo Editor

    A comprehensive editing feature that erases unwanted objects within an image (eraser) or fills in missing areas (outpainting).

How the Credit System and Pricing Structure Work

Remaker login screen: 30 free credits upon first use, register with Google account or email address

Using Remaker AI requires “credits.”
Upon registering an account (you can log in with a Google account, etc.), you are granted 30 free credits. Even with just this free allowance, you can try face swapping anywhere from several to over a dozen times.

Credit Consumption Per Feature

The amount of credits consumed varies depending on the feature and settings (such as high-quality mode or video length).
Since the “consumed credit amount” is displayed each time near the execution button, be sure to check it before generating.

Paid Plans Focus on One-Time Purchases

While many AI services adopt a monthly subscription model costing several thousand yen, a major advantage of Remaker AI is that you can choose a prepaid system to “buy only what you need, when you need it.”

  • 150 credits for $2.99 (approx. 450 JPY)
  • 1,100 credits for $19.99 (approx. 3,000 JPY)

Because you can top up with small amounts like this, it’s also ideal for spot usage, such as wanting to create a lot of images just for this weekend. Of course, there is also a monthly VIP plan for frequent users.

1. In-Depth Guide to Face Swap: From Still Images to Videos

“Face Swap” is the signature feature of Remaker AI.
It doesn’t just paste faces on top; the AI advancedly calculates lighting, skin tone, facial angles, and more to synthesize them with startling naturalness.

[Basic Edition] Swap Face (Single Face Swap)

This is the most basic one-on-one face swap. You can put your own face onto a model’s photo or turn historical figures into modern styles.

STEP
Upload

Drag and drop the base image into “Original Image” on the left, and the photo of the face you want to insert into “Target Face” on the right.
*Previously used images can be selected from history.

STEP
Execute Generation

Click the “Swap” button at the bottom center. Wait a moment for processing to complete.

[Advanced Edition] Multiple Face Swap

Use this when multiple people appear in the image, such as in group photos or couple pictures.

  1. When you upload an image, the AI automatically recognizes all faces in the image and lists them.
  2. A plus button to select a “Target Face” appears below each recognized face.
  3. Specify the target image only for the faces you want to change. Faces left unspecified will remain as they are.

This allows for advanced editing, such as “changing only the bride and groom’s faces to your own in a wedding group photo.”

[Expert Edition] Video Face Swap

This is a feature that replaces the faces of people in videos rather than still images. While extremely powerful for YouTubers and TikTokers, there are points to keep in mind.

  • Processing Time: Because it processes every single frame of a video, generation takes longer than for still images.

2. In-Depth Guide to Image to Video: Prompts are Key

Generated Video

This is a feature that creates motion such as hair blowing in the wind, flowing clouds, or blinking from a single still image. It is extremely useful for commercial production and social media short video materials.

Prompt Strategy: Syntax for Creating Videos as Intended

Here are some prompt tips for giving precise instructions to the AI. Try combining the following elements and entering them in English.

[Subject] + [Action] + [Environment/Background] + [Camera Work]
Example: A beautiful woman, [smiling and blinking], [wind blowing her hair], [cherry blossoms falling in background], [slow zoom in camera]

  • Subject: A cat, A car, A cyberpunk city, etc.
  • Action: walking, running, crying, laughing, etc.
  • Environment: rain, snow, sunny, neon lights, etc.
  • Camera: zoom in, pan right, static shot, etc.

3. Other Useful Tools: Background Removal, Upscaling, and AI Editing

Though not flashy, these toolsets dramatically improve your daily work efficiency.

Background Remover

Ideal for creating product images for e-commerce sites or cutting out people for YouTube thumbnails. Simply upload and wait a few seconds to download a transparent PNG image.

Image Upscaler

Converts photos taken with old digital cameras or flip phones, or low-resolution images created with generative AI, into high resolutions that can withstand printing.

  • 2x / 4x Upscale: Doubles or quadruples the image size.
  • Face Enhance: AI redraws facial details (eyes, nose, mouth) to make them sharp and clear. An essential option for portrait photos.

AI Photo Editor

“I want to erase a passerby who wandered into this shot.” “I want to make birds fly across the sky.” This tool grants those wishes.

Image editing tool: add or replace brush tool is selected, brush size adjustment and SD1.5 or Flux models can be chosen
  • Eraser: The AI fills in and erases the part traced with a brush to match the surrounding background.
  • Inpaint: Adds an object instructed by a prompt (e.g., “sunglasses”) to the traced area.
  • Outpaint: The AI imagines and draws the outside of the image, widening the field of view.

What Can You Do with Remaker AI?

Scenario 1: Creating Materials for Wedding Movies

Childhood photos of the bride and groom are often old and poor in image quality.

  1. Enhance quality with Upscaler.
  2. Create parody images where the two look like a movie poster using Face Swap.
  3. Add a smiling motion to the two using Image to Video.

With just this, you have all the materials ready for an opening movie.

Scenario 2: Reducing Model Photography Costs for E-Commerce Sites

Shooting model photos wearing product clothing every time is tough work.

  1. Shoot clothes dressed on a torso (mannequin).
  2. Change the mannequin’s face to a realistic AI model’s face using Face Swap.
  3. Make the background white-transparent using Background Remover.

You might be able to drastically cut down on model and studio fees.
