Shared memory layer for LLMs. Store documents, knowledge and notes in a single portable database and access them from any MCP-compatible client — Claude Code, VS Code Copilot, ChatGPT, Mistral Vibe, custom agents, or anything that speaks MCP.
Runs privately in a Docker container or natively. Your data never leaves your machine.
Every LLM session starts from scratch. Claude doesn't know what ChatGPT learned yesterday. Your Copilot session can't access the architectural decisions you discussed with Claude last week. Each tool operates in complete isolation.
Mnem-O-matic fixes this by providing a shared, persistent memory that any LLM can read from and write to.
Documents — reference material, code snippets, specs, configs, notes. Anything you want LLMs to have access to.
Knowledge — discrete facts, decisions, and observations. "The auth system uses JWT with RS256." "We chose Postgres over SQLite for the main database." "The deploy pipeline runs on GitHub Actions."
Notes — quick thoughts, ideas, observations, and voice transcripts. Informal content that LLMs should be aware of but that isn't structured enough to be a document or atomic enough to be a knowledge entry.
All types support namespaces (per-project or global), tags, and metadata. Everything is searchable via full-text and semantic search.
A sample agent skill file is included at skills/mnemomatic/SKILL.md. It teaches an agent how to use Mnem-O-matic effectively — when to search, which search mode to pick, what content type to store, and how to retrieve full content after a search.
The skill is written for Claude Code but can be adapted to any agent framework that supports custom instructions or skill files. Tailor the wording, triggers, and examples to match your agent's terminology and workflow.
