Featured Technologies
Six core systems that define SumiSplash as a professional-grade manga and anime drawing platform.
Liquify Engine
Mesh-based deformation with a 20x20 vertex grid for smooth, high-quality warping. Push, pull, and distort areas of your drawing to adjust proportions, tweak expressions, or add dynamic flow to hair and clothing without redrawing.
11 Specialized Tools
From precision Brush and Fill tools to advanced Lasso selection, Action FX speed lines, Speech Bubble creator, and Panel divider tool. Every tool a manga artist needs in one streamlined toolbar.
12 Professional Brushes
6 free + 6 Pro brushes covering every manga workflow: Ink Pen for lineart, Cel Shader for flat colors, Screentone for halftone shading, Watercolor for soft washes, plus Sparkle, Glow, Splatter, Chalk, Charcoal, and Marker.
Anime Color Palettes
5 curated 10-color palettes designed for specific manga genres: Shonen (bold action reds), Shoujo (soft romance pinks), Cyberpunk (neon sci-fi), Pastel K-pop (cute modern), and Seinen (mature earth tones).
Speech Bubble System
Draw speech bubbles directly on canvas with 4 styles: Oval (standard dialogue), Square (narration), Thought (internal monologue), and Action (shouts/SFX). Drag to size and position with clean vector rendering.
Action FX Tool
Add dynamic speed lines and action effects that follow your brush stroke direction. Essential for fight scenes, dramatic reveals, and any moment that needs kinetic energy in your manga panels.
Technical Specifications
Built with Kotlin and Jetpack Compose, powered by Hilt dependency injection, and engineered with a custom Canvas API drawing engine and 20x20 vertex mesh deformation.
