nambok / mentedb
A cognition aware database engine for AI agent memory. Purpose built in Rust with WAL, HNSW, knowledge graphs, and speculative context pre assembly. Not a wrapper, a ground up storage engine that thinks.
Why this job: topics: rag, vector-database, knowledge-graph
What it does
- Automatic Memory Extraction LLM powered pipeline extracts structured memories from raw conversations
- Entity-Centric Memory Extracts typed entities (person, pet, place, event, item, organization) with structured attributes. Entity resolution merges attributes across mentions. Derived and labeled Related edges link entities to the memories t
- Hybrid Retrieval Vector similarity (HNSW) fused with BM25 keyword search via reciprocal rank fusion, plus tag, temporal, and validity filtering. Optional second-pass reranking (pluggable, e.g. a cross-encoder or LLM judge) and optional MMR
- Contextual Retrieval An optional per-memory context blurb is indexed and embedded alongside the content (never stored in it), so a memory is findable by situating terms it never literally contains. The caller generates the context; the engi
- Project Scope Weighting Recall can weight down memories tagged for other projects so the project you are working in ranks first, without hiding a strongly relevant cross-project memory
