Aseprite plugin

Install the Sprite AI extension for Aseprite and generate + animate pixel art with AI, without leaving the editor.

The Sprite AI extension adds Generate and Animate to Aseprite's Sprite menu. It uses your account tokens. No companion app, nothing running in the background.

Requirements

Aseprite 1.2.10+ (1.3 recommended). LibreSprite is experimental.
curl on your PATH (it ships with Windows 10+, macOS, and most Linux).
A free Sprite AI account and an API key.

Install

Download the extension, then double-click it (or Edit > Preferences > Extensions > Add Extension) and click Install.

Set your API key

Create a key at your account API keys, then paste it into File > Scripts > Sprite AI: Set API key. It verifies on save and shows your account.

Cost

Command	Cost
`Generate`	1 token (4 for tile, background, ui, effect)
`Animate`	14-28 tokens
`Match the current canvas`	Free

Troubleshooting

"Could not reach the API" — check that curl --version works in a terminal.
Key rejected (401) — re-paste the full sai_sk_ key.
Can't animate the canvas — the source must be 256px per side or smaller.

Prefer an AI editor? Use the MCP server instead. Same account, same tokens.
