đ cognee Update: September 2025
Vasilije MarkovicCo-Founder / CEO
Hey there, cognee community!
September was a sprint. We ran a full Launch Month, upgraded retrieval and graph intelligence, merged a ton of community PRs, hit Github trending again, and showed up at events across the memory/context for AI agents ecosystem. Hereâs the quick list and then the details.
At a Glance
- Launch Month with daily drops: We started with our new evals, product announcements like memify pipeline, auto-optimization, three case studies - still counting.
- Cognee UI: local & cloud (Cognee Cloud) notebooks plus a Graph Explorer.
- Retrieval upgrades: a new lexical-chunk retriever, temporal fixes, feedback loops.
- Graph intelligence: ontology resolver + matching strategies, time-graph options, more.
- Adapters: new DuckDB vector adapter, Pinecone in community adapters, FalkorDB/Chroma updates.
- Community wins: we hit GitHub Trending, again!**.
- We were on the road (and air): talks, conferences, meetups, and partner sessions with Redis, Neo4j, and more.
- Challenge: the September âContribute to Winâ challenge wraps todayâwinners announced in the next days.
Launch Month recap
Memify: Memory enrichment layer
Memify lets you treat post-processing as a first-class pipeline: adjust structure, fix entities, or add relationships and persist the deltasâno full rebuild. Itâs live with docs + beta access.
Memory Auto-Optimization with Feedback Loops
With cognee's memory auto-optimization, rated responses aggregate into weights on the edges used to answer questions. Those weights guide future ranking so relevance improves with real usageâless manual prompt twiddling.
The new Cognee UI
The new Cognee UI gives you one workspace for adding data, cognifying, querying, and exploring the reasoning subgraph using notebooks. Run locally, hook your cloud datasets, and visualize results in Graph Explorer (enable use_combined_context=True).
Graph-aware embeddings
Introduced Graph-aware embeddings fusing semantic vectors with graph signals (hierarchy, time, entity types) to improve ranking precision, context fidelity, and latency via smarter reranking. Available in paid plans; fully compatible with our open-source stack.
Case studies we shipped
- Knowunity (EdTech): we mapped 40,000 German learners to surface likely classmates and study partners using proximity + academic contextâturning isolated effort into networks. Read more here
- UWYO (Education policy): turned scattered PDFs into an evidence graph that answers natural-language questions with page-level provenance; built for teacher workflows. Read more here
- Tier-1 US bank (Financial services): delivered a semantic layer that unifies card rules, APRs, rewards, and fees for precise, auditable answers. Read more here.
Product Highlights
Retrieval & Reasoning & Graph Intelligence
- Feedback loops enabled during search, scores are written back to enrich the graph
- Ontology resolver improvements
- Time graphs: toggle validity windows
- Temporal retriever improvements: more consistent âas-ofâ answers.
- Graph-aware embeddings fuse semantic vectors with graph signals (hierarchy, time, entity types) to improve ranking precision, context fidelity, and latency via smarter reranking.
Cognee UI & DX
- Programmatic UI start + auto-start backend for frictionless local runs.
- Simplified search endpoint, graph-view + search harmony.
- New starter notebook on UI
- Clearer errors, quieter logs, and CI reliability tweaks.
Adapters & Connectors
- DuckDB vector adapter
- Pinecone adapter added to community set.
- Chroma and FalkorDB updates; adapter tests tightened.
Agent Frameworks / MCP
- Easier CLI flows to start MCP from the UI, version bumps, and better serialization/return types.
- We integrated with LangGraph. Many more integrations are in the queue.
Community & Events
- Our September âContribute to Winâ challenge closes today. Weâll highlight a selection of PRs and announce winners in the next days.
- We showed up on GitHub Trendingâthank you for the stars, forks, and shout-outs from our community and partners!
- We were out in the wild: Conferences meetups, partner webinars, community newsletters (Year of the Graph), many blog/social media posts from our community.
Some of the highlights:
âď¸ AI Alliance Ă Cognee
âď¸ Redis Released â SF
âď¸ Graph Exchange (Fall 2025, SF)
âď¸ DuckDB Podcast
âď¸ AI Engineer Paris
âď¸ Qdrant Vector Space Day
âď¸ Memgraph community webinar
If you met us at any of these, thank youâthese already helped shape our approach this month!
Whatâs Next
We continue shipping!
Expect many more integrations with Agent frameworks and exciting product announcements.
This month we'll focus even more on building with you, improving with your feedback, refining our docs.
