Communitarian Technology
A gathering place for
minds at the threshold
Video calls, a 2D spatial world, and community AI —
owned and governed by its members.
What is Castalia?
Castalia is an ecosystem of tools owned and governed by its community. Not a platform extracting value from its members — a commons for minds that gather at the edges of conventional thought.
Three tools, one coherent space: simple video calls, a 2D spatial world where your conversation unfolds around you, and an AI assistant built communally — trained on your knowledge, answering to your values.
The technology is the medium, not the message. What matters is the quality of thought that emerges when people gather with intention, ambient support, and genuine shared governance.
