Shodh Memory
Local, LLM-free persistent memory for AI agents — Hebbian learning, offline, 30MB binary.
Shodh Memory is a unique, zero-LLM memory store for agents that need fast, deterministic, and private recall on edge hardware. It outpaces vector-only solutions for causal reasoning but lacks cloud sync or enterprise management. Best for developers who want local, auditable memory without API costs.

About Shodh Memory
Shodh Memory is a local-first persistent memory system for AI agents that operates without any LLM calls. Unlike conventional memory solutions that invoke an LLM for every store, consolidate, or recall operation, Shodh uses Hebbian learning rules and decay curves to strengthen frequently co-accessed memories and let irrelevant ones fade naturally. The result is deterministic, auditable, microsecond-speed memory operations that never leave the user's machine. The tool is designed for developers building autonomous agents, robotics systems (ROS2/Zenoh), edge devices, and air-gapped environments. It runs as a single ~30MB Rust binary with no Docker or external dependencies. It provides a knowledge graph augmented with temporal indices and hybrid ranking, enabling causal retrieval and blind spot detection that vector-only memory stores cannot achieve. Shodh integrates with Claude Code, Cursor, Windsurf, Claude Desktop, VS Code (Continue extension), and Docker. It offers a REST API, 37 MCP tools (as per current docs), and client libraries for npm, PyPI, and crates.io. All operations run fully offline, making it suitable for Raspberry Pi, Jetson, and industrial PCs. What sets Shodh apart is its cognitive architecture: Hebbian strengthening, natural decay, spreading activation, and diagnostic introspection (detecting blind spots, orphaned clusters, stale zones). It is open source (Apache 2.0), backed by published research, and features 1,089 tests. Latest posts highlight causal retrieval — a feature that vector-only solutions cannot replicate, and a strong argument for replacing ephemeral few-shot learning with persistent memory.
Behind the Verdict
Shodh Memory takes a genuinely different path from mem0, Zep, or cognee by never calling an LLM in the memory loop. Instead, it uses Hebbian learning and decay curves — algorithms that run in microseconds and produce deterministic results. That means no surprise bills, no latency spikes, and no privacy trade-offs: every memory stays on your machine in a ~30MB Rust binary. We'd reach for Shodh when building autonomous agents that need persistent, ground-truth memory without reliance on cloud APIs or LLMs. The causal retrieval feature — highlighted in recent blog posts — reconstructs chains of reasoning, answering "why did I decide X?" in a way vector memory cannot. That's a real edge for debugging agent behavior or building explainable systems. Where it bites: there is no native cloud sync or team-sharing. If your use case demands collaborative memory across devices or a hosted management UI, you'll need to build that yourself. Enterprise features like SSO and RBAC are not available yet. And non-technical users won't find a GUI — it's primarily CLI and API. Compared to mem0, which also offers open-source memory but leans on LLM calls for summarization and enrichment, Shodh is faster and cheaper per operation (literally $0). However, mem0 provides a cloud-hosted option and a higher-level API for less technical teams. Similarly, Zep and cognee offer cloud sync and team features but charge monthly fees. In practice, Shodh shines on edge devices: Raspberry Pi, Jetson, industrial PCs. It's also a strong choice for robotics workloads via ROS2/Zenoh. The published benchmarks (<1μs graph lookups, 34-58ms semantic search) are backed by 1,089 tests. Just don't expect a polished frontend or enterprise support — this is a developer's tool first.
