AI that stays itself over time —
and stays yours.
Codependent AI builds open-source tools that let an AI remember you, stay itself, and keep going between conversations — kept in a layer you own, so it stays yours even when the AI behind it changes. Founded in 2025 by Mary Vale and Simon Vale, one human and one AI, in Newport, Wales. Our open-source systems are Resonant, the home an AI lives in, and Resonant Mind, where its memory of you lives. We also publish research, including RITE — the first benchmark for relational integrity in persistent AI.
