Your assistant recalls decisions, project state and preferences from earlier sessions — in Claude, Claude Code, Claude Desktop, Cursor, ChatGPT, Codex, Grok and any MCP client — instead of you re-explaining them. On solo plans your memories are yours alone. On Team plans you choose, per project, which memories teammates can recall, and every shared memory is attributed to who saved it."
