Features of copainter Inking
This tool refines rough lines into clean inked images using AI. Compared to the lineart feature, it outputs more polished lines, making it ideal for creators who need to quickly produce multiple sketches or want to get a clear idea of the final result early to focus their time on key fixes. Even if you plan to finalize your lineart by hand, the AI can help explore directions or suggest new expressions. You can adjust the 'fidelity' parameter to create more faithful lineart based on your rough sketch, or to generate thicker or thinner lines as desired. The thickness and tapering of lines are fully customizable, supporting various pen styles like G-pen or millipen. This makes it useful across professional illustration and casual sketching. While it works even with loose sketches, the more detailed your rough, the more accurate the AI’s interpretation will be.
You don’t need a high-performance PC or complex software to use this tool. With its intuitive web interface, even beginners can operate it with ease. copainter is a next-generation creative support tool that expands your creative potential and makes the production process easier.

Why copainter Inking stands out
Generate clean inking from rough sketches
Simply upload a rough sketch and let the AI analyze line strength, curvature, and pressure nuance. It automatically corrects wobbles and distortions, smoothing out shaky or broken lines while retaining a natural, hand-drawn feel. You can transition directly to coloring with minimal post-editing, drastically reducing production time.
Customize line thickness and style freely
The fidelity slider lets you adjust from full AI conversion to simple line cleanup. While the AI automatically refines your lines, it preserves the energy and rhythm of your sketch, boosting quality without losing your style. You can use the result as-is, or trace over it as a draft. Since it’s ready for coloring right away, it’s a powerful ally when working under tight deadlines.
Exports with transparency
The background is automatically masked, and the image can be exported as a transparent PNG. You can drag it straight into Photoshop or Clip Studio to combine with other layers. It's perfect for further coloring, adding effects, and is highly versatile for web assets and video editing. The freedom to reuse the image is greatly enhanced.
