Second Brain

Overview

Second Brain is a shared context layer in Notion, exposed through the Notion MCP server. The point is that 4–6 agents across 3 active projects read and write the same state, instead of each one drifting off a stale copy.

What I built

• A Notion workspace the agents can reach through MCP, so ongoing work stays in one place
• A proactive Grok bot that asks questions about that work, surfaces priorities, and writes updates back to Notion — context stays current without someone pasting status updates by hand
• A content path for Builders Collective Ottawa, where agents share brand and event context and draft posts and announcements from it

Design notes

• One source of state: if it isn’t in Notion, the agents don’t get to invent a second version.
• The bot does the upkeep: questions and writebacks replace a manual status ritual.
• Brand context included: drafts for the collective come from the same place as the project notes.
