We have a lot of different surfaces for my start up, and our whole team had individual patched their own silo'd solution together with their agent, github, slack, granola etc. Most founders I chat with I ask "what are you doing for a team brain/data lake?" and most have some sub optimal, stuck-together fix. So I've been looking for this exact thing, Ozbrain, for months. And my review after two weeks using it daily:
it does exactly what I need, it's slotted sleamlessly into my daily work flow, it's great. The versioning is really cool too, we take it for granted with code and git, but having it for company wide knowledge/data is great. Make so much sense.

It's truely MCP first, set up was a prompt and a few follow up questions in my agent, super simple.
