mirAI is an AI scripting assistant for After Effects that turns natural language prompts into scripts and expressions. Powered by Google Gemini and OpenRouter, it reaches more than 300 AI models — including GPT, Claude, Grok, DeepSeek, Llama, and Mistral — through a single API key, and lets you switch between them instantly. You can also connect any OpenAI-compatible endpoint or your own local server.
Beyond plain scripting, mirAI leans AI-first: type a word such as "butterfly" to get an original point cloud, or use AI AUTO for a full auto scene with shape, motion, and color. Stackable motion tags cover turbulence, swirl, explosion, assemble, connect-lines, trails, and a gravity-sphere attractor. It is AE-aware, sending particles along your camera or a layer's path while reading Position keyframes and mask or shape Bézier curves, and its Storyboard mode morphs multiple cuts in order, matched to the active comp camera.
The core logic has been refined over time to cut redundant data processing and keep token usage efficient. The developer advises saving your project before running any AI-generated script.
