About Cipher by Byterover
Cipher by Byterover is an open-source persistent memory layer designed specifically for AI coding agents, compatible with Cursor, Claude Code, Gemini CLI, Windsurf, VS Code, and more via the Model Context Protocol (MCP). It captures two memory types — System 1 (programming concepts, business logic, past interactions) and System 2 (the AI's own reasoning steps) — plus a shared Workspace Memory that syncs team knowledge across IDEs and sessions. Cipher automatically creates and retrieves memories without manual input, giving AI agents persistent context across projects, sessions, and team members.
