In anime, manga, and webtoon production environments, the workflow is typically divided into specialized stages:

• Rough
• Line art
• Flat coloring
• Coloring
• Background
• Finishing
• Upscaling
• Revisions

However, most image generation AIs are designed with the assumption of:

“Generating a complete illustration in a single step.”

As a result, the following problems arise:

• Cannot be integrated into existing workflows
• Poor compatibility with team-based production
• Limited ability to revise or partially adjust images
• Difficult asset management

copainter is designed with the exact opposite philosophy.

Today, it has been adopted not only by individual creators but by over 100 companies, and is increasingly being used in anime, manga, webtoon, and illustration production environments.

1. AI That Works at Each Production Stage

copainter decomposes AI tools according to production steps.

▪ Character Production Stages

• Line Art AI
• Flat Coloring AI
• Coloring AI
• Rough-to-Color AI
• Inking AI
• Pose Conversion AI
• Angle Conversion AI
• Image Conversion AI

In other words, you can use AI only for the stage you are currently working on.

Rather than replacing your production workflow,
copainter extends and optimizes it.

2. Why copainter Fits Team-Based Production

■ Compatible with Division of Labor

• Key animation → Line Art AI
• Coloring team → Coloring AI
• Background team → Background Conversion AI
• Finishing → Upscaling AI

Each tool can be used independently at the appropriate stage.

Instead of relying on a single “genius AI,”
copainter functions as:

“Assistant AIs for each production stage.”

■ Designed for Revision-Based Production

In anime and manga production, the following are routine:

• Partial revisions
• Layer-level corrections
• Regenerating only the character
• Changing only the background

copainter supports a revision-first design, including:

• Background removal
• Image conversion
• Partial regeneration (coming soon)
• Layer separation (coming soon)

This is fundamentally different from AI tools designed only to output finished illustrations.

3. Evolving into a Studio-Specific AI Through Training

copainter enables training at each stage:

• Line art training
• Coloring training
• Image conversion training

This allows you to train AI on:

• A studio’s unique art style
• Project-specific visual direction
• Series-specific color design

This is critically important for enterprise use.

copainter is not just a “general-purpose AI.”
It can evolve into:

A studio-specific AI tailored to your production.

This is one of its greatest differentiators.

4. AI Assistant as a Creative Partner

copainter includes AI Assistant (Basic / Pro) features.

For example:

• Color design suggestions
• Composition improvement proposals
• Automatic generation of reference materials
• Prompt support

It is not merely a generation tool.

It can function as:

An AI production partner.

Benefits for Enterprises

1. Increased Productivity

Automation at each production stage shortens overall production time.

2. Reduced Dependency on Individuals

Training the AI ensures stylistic consistency and reproducibility.

3. Lower Revision Costs

Partial regeneration and background replacement are streamlined.

4. Support for Training Junior Artists

Using AI as a support tool improves training efficiency.

Conclusion

Many AI tools aim to:

“Replace production.”

copainter aims to:

“Become part of production.”

For anime and manga production teams, what’s needed is not a universal one-shot illustration generator.

What’s needed is AI that integrates naturally into the production workflow.

copainter is designed for exactly that purpose.
