Grok Build — xAI’s coding agent — now keeps persistent markdown notes on project conventions and decisions, and reads them back in later sessions. The agent stops re-learning your codebase’s habits every time you open a new chat.

It’s live for new sessions. For anyone using Grok Build on real projects, this is the difference between a clever autocomplete and a collaborator with a memory.

Memory is becoming table stakes for coding agents — Claude Code, Codex, and Copilot all have some form of it. xAI is just catching up, in public, on a live product.
