Features

• Hybrid search -- FTS5 full-text + sqlite-vec semantic + reranking for precision
• Knowledge graph -- Automatic entity extraction and relation tracking across memories
• Importance scoring -- LLM-scored 0.0-1.0 per memory for smarter retrieval
• Auto-archive -- Configurable age + importance threshold to keep memory clean
• STM-to-LTM consolidation -- LLM summarization of related memories in a category
• Duplicate detection -- Warns before adding semantically similar memories
• Zero config -- Built-in local Qwen3 embedding + reranking, no API keys needed. Optional cloud providers (Jina AI, Gemini, OpenAI, Cohere)
• Multi-machine sync -- JSONL-based merge sync via embedded rclone (Google Drive, S3, Dropbox)
• Proactive memory -- Tool descriptions guide AI to save preferences, decisions, facts
