Open Brain pitches thinking infrastructure layer

This is more ambitious than a notes app: OB1 is trying to become the source of truth your agents consult, not just another interface you visit. The pitch lands if you buy into a personal knowledge base as AI infrastructure, but the setup and behavior-change burden is still real.

• –Supabase-backed storage plus vector search makes the "shared memory" idea concrete instead of hand-wavy
• –MCP support and Slack capture point at agent workflows, not just human note-taking
• –The extension path for CRM, meal planning, and job hunting suggests a personal operating system, not a single-purpose app
• –The biggest challenge is adoption friction: the system only pays off if you consistently feed it useful context
• –If OB1 grows, the moat is likely the data model and integrations, not the front-end surface
