• 🎯 Advanced Queries - Full-text, date ranges, tag filters (AND/OR/NOT), hybrid search
• 🔀 Cross-references - Auto-linked related memories based on similarity
• 🤖 LLM Deduplication - Find and merge duplicates with AI-powered comparison
• 🔗 Memory Linking - Typed edges, importance boosting, and cluster detection

Tools & Visualization

• ⚡ Memory Automation - Structured tools for TODOs, issues, and sections
• 🕸️ Knowledge Graph - Interactive visualization with Mermaid rendering and cluster overlays
• 🌐 Live Graph Server - Built-in HTTP server with cloud-hosted option (D1/Pages)
• 💬 Chat with Memories - RAG-powered chat panel with LLM tool calling to search, create, update, and delete memories via streaming chat
• 📡 Event Notifications - Poll-based system for inter-agent communication
• 📊 Statistics & Analytics - Tag usage, trends, and connection insights
• 🧠 Memory Insights - Activity summary, stale detection, consolidation suggestions, and LLM-powered pattern analysis
• 📜 Action History - Track all memory operations (create, update, delete, merge, boost, link) with grouped timeline view

Install
