Score: 6.5/10 (Innovation: 7, Technical: 6, Documentation: 8, Utility: 5)

Rutter is a personal memory layer for AI agents that stores session summaries and decision records as plain markdown files in your own notes folder, using an MCP server to share memory across multiple AI clients like Claude Code, Grok, and Codex. It innovates by capturing append-only records with content hashes of cited notes, enabling cross-tool recall of past decisions without vendor lock-in. The approach is portable, greppable, and designed for users who already keep markdown notes.

Target audience: developers using AI coding assistants who maintain markdown notes
