Personal memory engine for AI agents — zero Docker, SQLite-everything (BM25 + sqlite-vec + SQLite graph)
Project description
kioku-agent-kit-lite
Personal memory engine for AI agents — zero Docker, SQLite-everything.
kioku-agent-kit-lite là phiên bản nhẹ của kioku-agent-kit, thiết kế để chạy hoàn toàn local, không cần Docker, không cần server nào. Mọi thứ đều trong SQLite.
Tính năng
- ✅ Tri-hybrid search — BM25 (FTS5) + Vector (sqlite-vec) + Knowledge Graph (SQLite)
- ✅ Zero Docker — không cần ChromaDB, FalkorDB hay Ollama server
- ✅ FastEmbed ONNX — embedding local, offline-capable (
intfloat/multilingual-e5-large) - ✅ Agent-driven KG — agent tự extract entities →
kg-index(không cần built-in LLM) - ✅ CLI —
kioku-lite save,search,kg-index,setup,init - ✅ Python API — import trực tiếp
KiokuLiteServicevào code - ✅ Multilingual — tiếng Việt, tiếng Anh và 100+ ngôn ngữ khác
- 🔜 MCP server — planned (v0.2)
Cài đặt
pip install "kioku-lite[cli]"
Quick Start
CLI
# Lưu memory
kioku-lite save "Hôm nay họp với Hùng về dự án Kioku. Rất productive." --mood work
# Tìm kiếm
kioku-lite search "Hùng làm gì gần đây"
# Index knowledge graph (agent tự extract entities)
kioku-lite kg-index <content_hash> \
--entities '[{"name":"Hùng","type":"PERSON"},{"name":"Kioku","type":"PROJECT"}]' \
--relationships '[{"source":"Hùng","rel_type":"WORKS_ON","target":"Kioku"}]'
Python API
from kioku_lite.service import KiokuLiteService
svc = KiokuLiteService()
# Save
result = svc.save_memory("Hôm nay gặp Lan và Minh ở cà phê.", mood="happy")
print(result["content_hash"])
# Search (BM25 + Vector + KG)
results = svc.search("Lan gặp ai hôm nay", limit=5)
for r in results:
print(r["content"], r["score"])
Agent Workflow
Workflow mẫu để AI agent (Claude Code, OpenClaw,...) sử dụng kioku-lite:
1. Agent lưu memory:
hash = kioku-lite save "..." --mood work
2. Agent extract entities từ context (dùng LLM riêng của agent):
entities = [{"name": "Hùng", "type": "PERSON"}, ...]
rels = [{"source": "Hùng", "rel_type": "WORKS_ON", "target": "Kioku"}]
3. Agent index KG:
kioku-lite kg-index <hash> --entities '<json>' --relationships '<json>'
4. Khi cần tìm kiếm:
kioku-lite search "Hùng làm gì" --limit 5
Thiết kế: kioku-lite không tự gọi LLM — agent chịu trách nhiệm extract entities từ context. Điều này tách biệt hoàn toàn memory store khỏi LLM dependencies.
Cấu hình
Cấu hình qua environment variables với prefix KIOKU_LITE_:
| Variable | Default | Mô tả |
|---|---|---|
KIOKU_LITE_USER_ID |
default |

KIOKU_LITE_DATA_DIR |
~/.kioku-lite/data |
Thư mục chứa SQLite DB |
KIOKU_LITE_MEMORY_DIR |

Thư mục chứa markdown files |
KIOKU_LITE_EMBED_PROVIDER |

KIOKU_LITE_EMBED_MODEL |
intfloat/multilingual-e5-large |
Model name |
KIOKU_LITE_EMBED_DIM |
1024 |
Embedding dimensions |
KIOKU_LITE_OLLAMA_BASE_URL |
http://localhost:11434 |
Ollama URL (nếu dùng Ollama) |
Hoặc dùng file .env:
KIOKU_LITE_USER_ID=phuc
KIOKU_LITE_EMBED_PROVIDER=fastembed
KIOKU_LITE_EMBED_MODEL=intfloat/multilingual-e5-large
Benchmark
Benchmark so sánh với kioku-agent-kit (full Docker):
| Metric | kioku full | kioku-lite | |
|---|---|---|---|
| Search latency | ~2–3s | ~1.2s | lite nhanh hơn |
| Precision@3 | 0.60 | 0.60 | Ngang bằng |
| Recall@5 | 1.04 | 0.89 | kit nhỉnh |
| Infrastructure | 3 Docker containers | Zero | lite |
Với cùng embedding model (
intfloat/multilingual-e5-large) và cùng Claude Haiku cho KG extraction, kioku-lite đạt chất lượng search bằng kioku full trong khi không cần bất kỳ Docker container nào.
