GitHub·high signal

claude-mem is a Claude Code plugin that continuously observes every coding session, compresses observations via AI to reduce token overhead, stores them in a local Chroma vector database with tree-sitter AST indexing, and injects relevant past context automatically into future sessions. It supports multi-provider backends (Claude, Gemini, OpenRouter), is worktree-aware, and generates distributed CLAUDE.md files across project folders. At 36,207 total stars gaining 1,017 today, it's the most-traction Claude Code memory solution yet and directly addresses the stateless-session problem every Claude Code user hits.
