Launch Celebration: Pre-Registration Campaign for the Learning Feature (Corporate Customers Only)!!

We’re running a pre-registration campaign to celebrate the launch of our new Training feature—free for the first 30 companies!

What is the Training feature?

This feature allows you to train AI on your own characters and art style. By training, copainter’s outputs can be aligned more closely with your trained character or style.

Problems it can help solve

With copainter’s Training feature, you can generate characters and styles more consistently.

For example, in anime production you may face issues such as:

• “Key animators’ habits vary too much”
• “The quality of first key frames is inconsistent…”

The Training feature may help improve these.

With character setting materials and rough sketches, you can generate a polished illustration from a rough in just tens of seconds using copainter’s image transformation.
You can also output not only full-color images but line art, and use them directly as references or underdrawings for quality control.

It can also help with challenges like:

• Producing large volumes of the same character for character-based games
• Generating in your own art style for manga production
• Keeping facial features, hairstyles, and outfits consistent for in-house characters
• Unifying styles across creators or projects
• Maintaining brand consistency across banners, LPs, and social media
• Reducing revision costs and back-and-forth during mass production

Two Training Types

1) Character Training (learn character-specific traits)

Goal: Reproduce a specific character’s face, hair, outfit, colors, accessories, etc. with high accuracy
Use cases: Company mascots, ad campaign characters, internal IP, etc.
Recommended data: Final finished illustrations only (exclude roughs / work-in-progress)

2) Style Training (learn rendering/style traits)

Goal: Inherit line quality, coloring, shading, saturation, and other stylistic elements
Use cases: Brand tone, series consistency, project-specific style guidelines, etc.
Recommended data: Include diverse characters/compositions/scenes, while keeping the style consistent

AI features supported with Training

• Line Art
• Inking

We also offer an optional paid “Training Support Plan” provided by our team.
