I've been thinking about this for a long time.
About what it means to think. To reason. To know.
Today we're introducing something I'm really proud of.
We call it Aristotle.
Wouldn’t be surprised if ethereum:0x66a5cfb2e9c529f14fe6364ad1075df3a649c0a5 would do the same or even better performance like zcash:native. Full send!
Companies have raised $47M building AI memory.
Mem0 — $24.5M
Letta — $10M
Cognee — €7.5M
All of them charge per memory.
None of them work offline.
None have a knowledge graph.
I built one that does all of it. For free.
Open source. MIT licensed.
And this is just v1 — the full cognitive upgrade drops soon.

Agreed — human links are implicit. That's exactly why we use spreading activation, not explicit graph traversal. The graph is substrate; activation patterns are the recall mechanism. Same principle as neural associative memory.
Pruning/remapping — solved with offline dream consolidation (batch dedup, merge, prune during idle). SYNAPSE (arXiv:2601.02744) proved activation-based graph recall beats flat vector on LoCoMo benchmarks.
Fair correction on pricing — updated. Letta's Postgres-based approach is solid for self-hosted.
On graphs: they're not for the model to reason over — they're for retrieval. Vector similarity finds what's similar. Graphs find what's connected. "Alice works at Google" + "Google is in Mountain View" — vector search won't connect those. Graph traversal + spreading activation will.
Complicated? Yes. That's the moat.
Benchmarks are coming LOCOMO + LongMemEval. Hindsight wins on recall. We're playing a different game: cognitive architecture (spaced repetition, spreading activation, fleet memory, dream consolidation). They're features that compose, not a feature checklist. But fair numbers talk. We'll publish them.

Free forever. No cloud lock-in.
And what's on GitHub right now? That's just the beginning.
The full cognitive engine — spreading activation, dream consolidation, knowledge graph enrichment — is being battle-tested on a 10-machine cluster as we speak.
v2 drops soon. Star the repo so you don't miss it.

Let's talk about what $47M in VC money built:
Mem0: 8 features. $0.01/memory. No graph. Cloud-only.
Letta: 6 features. Server required. Limited agents.
Cognee: 5 features. LLM-dependent pipeline.
Mnemosyne: 33 features. $0/memory. Full graph. Works offline. Multi-agent native.
Not funded. Not backed. Just built.
