An end-to-end agentic memory framework built around CogniGraph, a lightweight hierarchical graph that uses entities and relations as semantic indexing layers. Targets efficient long-term reasoning: keep the memory graph small and the retrieval cheap while preserving multi-session recall. Published as an arXiv 2025 paper with public code.
- Storage
- CogniGraph — a hierarchical graph of entities and relations serving as semantic indexing layers, backed by dense embeddings (BGE-M3 in the paper's evaluation).
- Retrieval
- Temporal- and hierarchy-aware search over the CogniGraph with integrated reranking, aiming for adaptive, coherent knowledge retrieval at low token cost.
- Self-host
- Self-host: moderate

Strengths
- Graph-structured memory (CogniGraph) with temporal + hierarchy-aware search and reranking
- Paper reports strong LoCoMo and LongMemEval accuracy at low token cost across two backbones
- Its evaluation provides a clean head-to-head re-run of Mem0/A-Mem/Zep (useful as an independent baseline source)
Watch out
- No LICENSE file in the repo — code is public but all-rights-reserved by default; not legally reusable until licensed
- Deprecated here: only 4 commits ever (a 3-day burst in Jan 2026), then no activity for ~6 months as of 2026-06-30 — a research code-drop, not a maintained framework. Revisit if the authors add a license and resume development
- Headline scores are self-reported (authors' own system); independent reproduction pending
Best for
- Researchers comparing graph-based agentic memory under a controlled, efficiency-focused evaluation
