> **Engram** gives AI agents a brain — not a database.
> It remembers what matters, forgets what doesn't, and builds connections between ideas.
> All inference runs **locally** — no API keys, no cloud, no token cost per memory operation.

## Why Engram?
Most AI memory solutions (like [Mem0](https://github.com/mem0ai/mem0)) use LLM calls for every `add()` — extracting facts, classifying operations, resolving conflicts. That's powerful, but **expensive** and **opaque**.
Engram takes a different approach:
| | **Mem0** | **Engram** |
| ---------------------------- | ------------------------------ | ----------------------------------------- |
| **Who decides what to save** | LLM automatically | Agent explicitly |
| **Cost per memory write** | LLM call (extraction + update) | Local embedding only |
| **Cost per memory read** | Vector search + LLM | Hybrid search + local reranker |
| **External dependencies** | OpenAI API / vector DB service | **None** — fully local |
| **Memory unit** | Atomic fact ("User prefers X") | Typed record with full context |
| **Forgetting** | No built-in mechanism | Ebbinghaus-inspired decay + consolidation |
| **Knowledge graphComments
