Why not just create a project in Claude with our documents?
That context sits in one project and goes stale. Your business changes daily; Heidi changes with it, and your whole company shares her. A project is a snapshot for a few people; the Cortex is a living memory for everyone.
Projects are great for a bounded task. A company brain has different requirements: continuous capture, hourly hygiene, permissions per fact, and answers available to every person and every tool.
And with MCP, Claude itself can read from Heidi, so you can have both: a project with a real brain behind it.
