IF I WERE STARTING FROM ZERO TODAY, I'D BUILD MY AI BRAIN ON GITHUB FIRST

Summary from the TLDR Marketing newsletter

A GitHub repository acts as a living brain, using markdown files to store priorities and decision logs. A background file holds key context while a journal file forces regular prioritization. A Claude Code routine runs in the cloud each night, scanning Slack, email, calendar, and meeting transcripts. It then drafts replies, updates tasks, surfaces summaries, and writes changes back to GitHub. Notion is used for drafting and editing, Slack is used for notifications through a custom bot, and the whole setup runs continuously without manual prompts.
