Real-time continuous affect engine

Anima

anima /ˈæn.ɪ.mə/

the soul, especially the irrational part of the soul as distinguished from the rational mind.

Anima extracts a living emotional state from raw text, and outputs a vector that can be broadcast to any downstream consumer.

One example use is generating in-flight modifications to body language and changes in eye-color with the related Reachy Mini Conversational App behavioral adapter for the Reachy Mini robot. To get a better sense of how the affect extraction engine works you can check out this writeup explaining the approach.

You can get a quick sense for how the engine converts text to an emotional vector by running:
uv run pytest tests/smoke.py

Installation

pip install anima-engine
