AI Sticker Tools

Open-source tools to go from idea → sprite sheets → LINE-ready ZIP.

These three tools form a complete flow: start with ideas, generate sprites and animations, then pack everything into a LINE Creators Market ZIP.

stickermind

Sticker inspiration studio: generate sticker themes, character settings, and dialogue through conversation and example prompts — so you can flesh out your series' world before you start drawing.

  • Brainstorm characters, relationships, and world-building for a new sticker series
  • Generate sets of dialogue lines and scenarios as drawing scripts
  • Pair with Sprite-Animator and LINE-Sticker-Packer for a complete idea-to-launch workflow
