mnemo-cortex vs brain.md

mnemo-cortex: Mnemo Cortex provides AI agents with persistent, local, and cross-agent memory, enabling deep recall, overnight synthesis, and structured fact management without cloud dependencies. It functions as a cognitive coprocessor, enhancing agent intelligence by automatically capturing and consolidating conversational context across multiple tools and sessions.; brain.md: brain.md is a local-first markdown editor and knowledge base designed to serve as a 'second brain' for both humans and AI agents. It integrates built-in semantic search (RAG) using local WASM ONNX embeddings or external LLM APIs, and provides a Model Context Protocol (MCP) server for seamless interaction with AI clients, all while keeping data in plain .md files.

Features

mnemo-cortex logomnemo-cortex
01Active Memory: Automatically captures, classifies, and consolidates agent interactions, learning what works over time.
02Cross-Agent Dreaming: Synthesizes recent memories across all agents overnight, creating shared context for collective intelligence.
03Structured Facts: Provides a key-value store with confidence tracking for sub-millisecond exact lookup of entities and attributes, enhancing knowledge accuracy.
04Local-first & No Cloud: Operates entirely on your local machine, guaranteeing privacy and independence from cloud services.
05Document Discovery (The Librarian): Indexes all workspace files (including content snippets) to enable agents to quickly find documents based on fuzzy descriptions.
brain.md logobrain.md
01Obsidian-compatible Markdown: Supports wikilinks, embeds, callouts, math, mermaid, tasks, frontmatter, and aliases; directly opens existing Obsidian vaults.
02Built-in Semantic Search (RAG): Features a per-vault embedded vector store (pure JS), with notes chunked, embedded, and indexed on every save. Supports pluggable embedders (local WASM ONNX, Ollama, OpenAI, etc.).
03MCP Server (Streamable HTTP): Mounts 17 tools and 2 resources on the same port, enabling AI agents like Claude Desktop to read, search, query, and write notes with per-folder permissions.
04Local-first & No Vendor Lock-in: Vaults are plain .md file folders, accessible by any editor, ensuring data ownership and full offline functionality, including embeddings.
05Git Autocommit & History: Automatically commits every save to Git, providing full version history, diffs, one-click restore, and manual checkpoints.

Use Cases

mnemo-cortex logomnemo-cortex
↳Providing AI agents with persistent, long-term memory that survives sessions and tool switches, preventing amnesia.
↳Facilitating seamless collaboration among multiple AI agents by sharing and synthesizing learned context overnight, making collective knowledge available.
↳Creating a private, self-hosted knowledge base for AI agents, ensuring data privacy and eliminating reliance on external cloud services.
↳Storing and retrieving structured factual information with confidence tracking for precise lookups, complementing semantic search for critical data.
↳Safely ingesting and managing developer behavioral claims into an agent's context, including review queues and content detectors for robust privacy and security.
brain.md logobrain.md
↳Personal Knowledge Management (PKM): Organize and manage personal notes and knowledge in an Obsidian-compatible, local-first markdown vault.
↳AI Agent Memory Layer: Provide a robust, privacy-preserving memory layer for AI agents to read, search, and write notes securely via the MCP server.
↳Context for LLMs: Supply relevant context to large language models by transforming personal notes into retrievable chunks for RAG queries, enhancing AI responses.
↳Offline AI Workflows: Perform semantic search and embedding generation entirely offline using the bundled WASM ONNX model, suitable for privacy-sensitive or disconnected environments.
↳Collaborative Agent Environments: Enable multiple MCP-compliant AI agents (e.g., Claude Desktop, Cursor) to interact with a shared knowledge base, with granular folder-level permissions.
