OMEM is an accountability layer for AI agents, built as belief-revision memory. Most agent memory overwrites facts when they change, so when a client or a security reviewer asks "why did the agent do that?", the evidence is already gone. OMEM keeps the record instead: contradictions...

As answered by people managing MemoryPlugin and OMEM.
OMEM's answer:
Most agent memory decides what is true: when two facts conflict, the newer one wins and the loser is deleted, usually by an LLM's judgment that leaves no trace. OMEM refuses to make that call. Both sides of a contradiction stay on the record, marked, with which one is currently believed. Every belief can answer why(): which source, when, on what basis, what it contradicted. A risky action waits for a named human approver, and refusals are recorded too. And the engine that reads the record is frozen: it must replay the whole log byte-identically, verified in CI on every commit, so not even an upgrade can rewrite an agent's past. Think of it as sworn testimony rather than a scratchpad.
OMEM's answer:
Choose by the question you need answered. If the question is "what does the agent remember about this user", tools like Mem0 and Zep are excellent: they use an LLM to distill conversations into memories with near-zero integration work, and their ecosystems are much bigger than ours. If the question is "why did the agent believe that, who approved the action, and can I prove the record was never rewritten", that is what OMEM was built for, and the recall tools cannot answer it, because the LLM that curated their memory left no defensible reason behind. Many teams honestly need both: a recall layer behind the model, OMEM in front of the action. Also worth knowing: every claim we make is backed by a CI test you can run, including one that fails the build if the server ever makes a non-loopback connection. Verify, don't trust.
OMEM's answer:
Two groups. First, teams that ship AI agents to clients: agencies, dev shops, and vertical SaaS whose agents act on someone else's behalf. They are the ones who get asked "why did it do that?" in a security review, and since the EU AI Act's logging obligations became enforceable, that question arrives in writing. Second, open-source builders who want memory with receipts on their own machine: it is one pip install, self-hosted, MIT, with no external services and no dependencies, and there are SDKs for Python and TypeScript, an MCP server for Claude, a LangGraph store, and an n8n node.
OMEM's answer:
OMEM stands for Operational Memory. It is built by one person, and it started with a simple observation: agent memory kept stating things with total confidence that were really a coin flip between two sources, because the losing source had been silently deleted. Fixing that meant taking an old idea from AI, belief revision, seriously: keep the claims, track what is currently believed, never destroy the evidence. Once the record existed, the rest followed from asking what it would take for someone to actually trust it: provenance for every belief, a frozen engine that replays the log byte-identically so upgrades cannot rewrite history, a human approval gate in front of risky actions, and MIT licensing, because a record you cannot audit down to the source code is just another thing you are asked to take on faith.
OMEM's answer:
Python, with zero runtime dependencies on purpose: pip install omem-infrastructure gives you the server, the engine, and the dashboard, running against SQLite by default or PostgreSQL if you prefer. The belief engine is versioned and frozen, and CI verifies on every commit that it replays the append-only log byte-identically. Around the core: a TypeScript SDK, an MCP server so Claude and other MCP clients can use it as memory, a LangGraph BaseStore integration, an n8n community node, and one-click deploys for Render and Fly. Everything is self-hosted; a CI test fails the build if the server ever opens a non-loopback connection.
OMEM's answer:
Honest answer: OMEM is early, and there are no named customers to point at yet. The software is free, MIT, and self-hosted, so nobody has to become a customer to run it in production. On the commercial side, a small number of hands-on design-partner pilots are open for teams that ship agents to clients and need to pass a security review; the pilot is risk-reversed, meaning if it does not produce a review-ready artifact, you do not pay. When the first references exist and agree to be named, this answer will name them.
