# Grok Adds Cross-Session Memory to Grok Build

The feature captures project conventions, decisions, and facts in the background as markdown notes to inform subsequent sessions.

- Notes are scoped per project, with a separate global set for cross-project preferences
- The /dream command consolidates recent notes into organized topic markdown files
- The /memory command opens a read-only browser to inspect captured notes by scope
- Memory excludes task state, tentative conclusions, secrets, and repository documentation
- Instructions in the active conversation take precedence over stored memory notes

## Why it matters

Developers using Grok Build no longer need to re-explain project conventions, architecture decisions, and setup commands across new sessions.
