The Problem AI assistants have amnesia. Every new Claude/ChatGPT/Cursor session starts from zero. You waste hours re-explaining your project architecture, coding preferences, and previous decisions. Existing solutions (Mem0, Zep, Letta) are cloud-based, cost $40-50+/month, and your private code goes to their servers. Stop paying → lose all your data. My Solution: Local-First, Free Forever Built a universal memory system that stores everything on YOUR machine, works with 16+ AI tools simultaneously, requires zero API keys, costs nothing. 10-Layer Architecture Each layer enhances but never replaces lower layers. System degrades gracefully if advanced features fail. Layer 10: A2A Agent Collaboration (v2.6) Layer 9: Web Dashboard (SSE real-time) Layer 8: Hybrid Search (Semantic + FTS5 + Graph) Layer 7: Universal Access (MCP + Skills + CLI) Layer 6: MCP Integration (native Claude tools) Layer 5: Skills (slash commands for 16+ tools) Layer 4: Pattern Learning (Bayesian confidence) Layer 3: Knowledge Graph (TF-IDF + Leiden clustering) Layer 2: Hierarchical Index (parent-child relationships) Layer 1: SQLite + FTS5 + TF-IDF vectors Research-Backed Built on published research, adapted for local-first:

A2A Protocol (Google/Linux Foundation, 2025) GraphRAG (Microsoft arXiv:2404.16130) MACLA Bayesian learning (arXiv:2512.18950) A-RAG hybrid search (arXiv:2602.03442)

Key difference: Research papers assume cloud APIs. SuperLocalMemory implements everything locally with zero API calls. How Recall Works Query "authentication" triggers:

FTS5 full-text search TF-IDF vector similarity Graph traversal for related memories Hierarchical expansion (parent/child context) Hybrid ranking (combines all signals)

Installation bashnpm install -g superlocalmemory Auto-configures MCP for Claude Desktop, Cursor, Windsurf. Sets up CLI commands. That's it. Why Local-First Matters

Privacy: Code never leaves your machine Ownership: Your data, forever Speed: 50ms queries, no network latency Reliability: Works offline, no API limits Cost: $0 forever
