Grok Build now has long-term memory too, with /dream automatically organizing project experience from each round.

Beating AI News Flash: Grok Build launches automatic long-term memory. After each task round, it records project conventions, decisions, and facts worth retaining long-term in the background, so the next time the same project is opened, it can pick up directly without the user needing to re-explain.

These memories are all saved in Markdown. /memory allows direct viewing, while /dream merges recent scattered notes into different themes such as testing and code style, and the system also automatically executes this periodically.

This approach is not new. Claude Code already added Auto Memory in February this year, similarly automatically recording project knowledge and organizing it into MEMORY.md and topic files, with /memory also available for viewing and management. Codex has since also added a mechanism for automatically extracting and organizing historical memory.
