> [[Working at Plastic|Open positions here]].

Welcome.

Here you'll find our blog, research, and public notes. You can also [engage with the ideas directly](https://github.com/plastic-labs/blog).

[Plastic](https://plasticlabs.ai) is an engineering-driven AI lab building at the intersection of machine learning and cognitive science.

Our focus is developing systems that map personal identity using AI-native memory & social cognition. These systems enable individually-aligned agents you can trust to act autonomously and agents with rich identities all their own.

The foundational layer of intelligence being built is just the beginning. Latent among the scores of specialized secondary and tertiary layers yet to be realized exists one for personal identity. 

We're building it.
