Table of contents
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
Status
2026-05-02 -- Architecture stabilization update
Past months saw significant churn around credential handling and the daemon-bridge auto-spawn pattern. This caused multi-process races, browser tab spam, and inconsistent setup UX across plugins. As of v, the architecture is stable: 2 clean modes (stdio + HTTP), no daemon-bridge layer, no auto-spawn from stdio.
Apologies for the instability period. If you encountered issues with prior versions, please update to v+ and follow the current
docs/setup-manual.md-- most prior workarounds are no longer needed.Related plugins from the same author:
- wet-mcp -- Web search + content extraction
- imagine-mcp -- Image/video understanding + generation
- better-notion-mcp -- Notion API
- better-email-mcp -- Email management
- better-telegram-mcp -- Telegram
- better-godot-mcp -- Godot Engine
- better-code-review-graph -- Code review knowledge graph
All plugins share the same architecture -- install once, learn pattern transfers.
