Training Feature Added to the Enterprise Plan! | How to Use copainter’s Training Feature

A Long-Awaited New Feature Has Arrived: The “Training” Feature (Enterprise Plan Only)

copainter, the AI service that supports illustration production, has introduced a highly anticipated new Training feature (available exclusively on the Enterprise plan).

With this feature, you can train AI on your own characters or art styles and retain custom models for use in line art generation, coloring, image transformation, and more.

What Is the Training Feature?

By training the AI on your own characters or visual styles, you can align generated illustrations more closely with your trained character designs or art style.

Two Types of Training

There are two training types. You can build dedicated models based on your needs:

• Character Training
  Accurately reproduces a specific character’s facial features, hairstyle, outfits, accessories, and more.
• Style Training
  Learns artistic traits such as line weight, coloring, shading, saturation, and overall rendering style.

Key Benefits

• Consistent brand expression
  Faithfully reproduce your characters and visual identity.
• Improved production efficiency
  Reduce outsourcing costs and revision workloads.
• Fast onboarding
  Training works even with small datasets, enabling quick deployment.

Problems This Feature Can Solve

• Manga production deadlines
  Limited time to improve quality → Generate line art in your own style to save time.
• Inconsistent animation artwork
  Variations in key animators’ styles and limited animation director resources → Train the director’s style to unify outputs and reduce correction workload.
• Inconsistent character designs in games
  Style drift across projects or artists → Train on past artwork to maintain a consistent character look.

copainter’s Training feature solves these challenges easily—directly in the browser.
