Memories.sh is an open source tool that abstracts the shared memory layer for AI coding agents. Save rules, skills, decisions, and project facts once, then generate native configs for Claude Code, Cursor, Copilot, Windsurf, Gemini, and more. Get semantic recall, local-first SQLite that works offline, and optional cloud sync. Includes CLI, MCP server, and TypeScript SDK middleware for memory-aware AI apps.
