Cognee is an open-source knowledge engine that gives AI agents persistent, learning memory without requiring you to architect a graph database from scratch. Under the hood it combines a vector store, a graph database (Neo4j), and semantic indexing into a single interface backed by four simple operations: remember, recall, forget, and improve. The magic is in the auto-routing recall layer. Rather than forcing developers to choose between similarity search and structured graph traversal, Cognee analyzes the query and picks the optimal strategy automatically. Session memory syncs to permanent graphs in the background, so agents accumulate knowledge across runs without any manual persistence logic. At 15k stars and growing fast, Cognee is quietly becoming the memory layer developers reach for when building agents that need to reference past work — think support bots, research pipelines, coding agents that shouldn't forget what a codebase looks like. It deploys on PostgreSQL with pgvector, integrates with OpenAI and Claude, and ships with Docker configs for Railway, Fly.io, and Render.

Elytro is a cryptocurrency wallet designed from the ground up for AI agents rather than humans. Built on Ethereum's ERC-4337 account abstraction standard, it lets agents autonomously create wallets, simulate and execute transactions, swap tokens, and automate payments — all without ever holding the user's private keys. The smart account architecture enforces spending limits, email 2FA, and social recovery directly on-chain as policy constraints. The product addresses a real gap in the agentic AI stack: current AI agents that need to transact on-chain either require unsafe key delegation or constant human approval loops that defeat the purpose of automation. Elytro threads this needle by giving agents programmatic access to a secure, policy-constrained wallet where the rules about what the agent can do are enforced at the contract level, not just in software. Launched on Product Hunt on April 20, 2026, Elytro is free to use and targets developers building autonomous agents that need to participate in onchain economies — DeFi strategies, NFT purchases, cross-chain bridging, and automated treasury management. As AI agents become increasingly capable of taking real-world actions with real economic consequences, infrastructure like Elytro becomes essential plumbing.
Reviewer scorecard
“Six lines of code for persistent knowledge graph memory across agent sessions? That's a genuinely useful abstraction. The auto-routing recall that picks the right search strategy (vector vs. graph) without manual tuning removes a real pain point. PostgreSQL + pgvector backend means you're not locked into a proprietary store. I'm integrating this into my next agent project.”
“ERC-4337 account abstraction is the right primitive for this — on-chain policy enforcement means spending limits aren't just soft constraints in my agent's code, they're cryptographically enforced. For anyone building agents that touch DeFi or need autonomous treasury management, this is the right architecture.”
“Another 'knowledge graph for AI' library in a space already crowded with Mem0, LlamaIndex memory, LangChain's entity store, and MemGPT. The 'six lines of code' promise falls apart when you need custom ingestion pipelines or production-grade tenant isolation. PostgreSQL + Neo4j + vector store is three moving parts for what often just needs a good retrieval strategy. Wait for the ecosystem to consolidate.”
“Giving autonomous AI agents financial capabilities is exactly the threat model that security researchers warn about. One prompt injection attack, one jailbroken agent, one hallucinated transaction, and your on-chain spending limits are the only thing standing between you and drained funds. Interesting concept but the risk surface is enormous and the market is still tiny.”
“Memory is the missing layer in the agent stack. Cognee's cognitive science-inspired architecture — remember, recall, forget, improve — maps remarkably well to how useful agents should work. The feedback loop that improves future responses is the critical piece. As agents run longer and longer tasks, systems like this become the connective tissue that makes them actually reliable.”
“Autonomous AI agents with cryptographically-enforced spending policies are a foundational piece of the agentic economy. When agents can transact, negotiate, and pay for services on our behalf within defined limits, the scope of what automation can accomplish expands dramatically. Elytro is early infrastructure for a world that's arriving faster than most realize.”
“If I'm building a research assistant or a content pipeline that needs to reference past projects, having persistent memory that actually understands relationships (not just semantic similarity) changes the game. The fact it supports multimodal ingestion means I can throw PDFs, notes, and transcripts at it without preprocessing gymnastics.”
“The creative applications are more interesting than they first appear — imagine an agent that can autonomously purchase stock assets, license music, or pay for API usage for a content pipeline, all within a budget I've defined on-chain. This is the kind of plumbing that makes fully automated creative workflows actually possible.”
