Corbell vs rekal

Corbell: Corbell creates a living knowledge graph of your multi-repo architecture by analyzing code and design docs. It generates AI-powered design specs that respect your team's established patterns, and facilitates task decomposition and export to project management tools.; rekal: rekal provides long-term memory for LLMs via an MCP server. It stores memories in a local SQLite file and retrieves them using hybrid search (BM25 keywords + vector semantics + recency decay). It works with any MCP-capable agent like Claude Code, Codex CLI, and OpenCode.
