alt Hacker NewsObsidian would fall into the same answer as how is this different than gBrain. Obsidian is a powerful and configurable... but requires more work to maintain and sharing knowledge with others is more difficult. I want this to be a super easy way for agents to connect to my knowledge, and make it easy for me to share my chunks of knowledge with my teammates and their agents. Just MCP in and have your agents get to work.
I'd say gBrain is also more structured to the priorities of a VC and less of a general-purpose graph-based memory. There are tons of hard-coded regexes that may work beautifully for Garry's priorities and workflow that don't fit other use cases, and are probably really brittle even if you're a VC who uses different words in your notes.
