Your vault is the memory. Claude, Grok Bot, Codex - same brain. Your vault outlives whichever CLI you switch to.
obsidian-second-brain: AI second brain for Obsidian - persistent memory for Claude Code, Codex, Cursor and Grok Bot
Crew works without Obsidian. Claude Code, Codex, Cursor, and Grok Bot share job records in any plain folder. Each agent sees what the others finished and can leave a lesson for review.
Grok Bot joins the same team through its existing runner. A lesson becomes a rule only when a human runs keep. Crew runs no background loop.
