One foundation. Different ways to use it.

We are developing intelligence infrastructure for a world shaped by human purposes and institutions: knowledge people can investigate, interfaces companies can build on, and context agents can use within defined authority.

Explore knowledge in context.

We are developing knowledge access that connects entities, relationships, and histories to their sources. People investigating a place or institution should be able to examine an account and judge its relevance.

Build on a common reference.

APIs and MCP interfaces are being developed around shared identities and context. Reading knowledge and requesting change require distinct authority, with people and agents carrying different responsibilities.
