Moldavite vs brain.md
Moldavite: Moldavite is a local-first note-taking application that stores all notes as Markdown files on your computer, ensuring data ownership and privacy. It integrates with AI tools via a built-in MCP server, offering features like semantic search, wiki-links, and multi-platform support across macOS, Windows, Linux, iPhone, and iPad.; 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
Moldavite01Local-first storage: All notes are plain Markdown files in a user-chosen local folder, ensuring data ownership and no vendor lock-in.
02AI and Agent integration: Built-in MCP server allows connection with AI tools (e.g., Claude, Cursor) for tasks like reading, searching, and creating notes using 'Moldavite Skills'.
03Advanced note management: Includes wiki-links, backlinks, graph view, tags, daily/weekly notes, and an opt-in local semantic search.
04Cross-platform synchronization: Offers optional iCloud Drive sync on Mac and dedicated apps for iOS/iPadOS, alongside Windows and Linux beta versions.
05Browser clipper & publishing: A browser extension to clip web pages into Markdown notes and direct publishing to WordPress.com.
brain.md01Obsidian-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
Moldavite↳Personal knowledge base: Create and manage a personal knowledge base with interconnected notes, semantic search, and robust organization.
↳AI-powered note interaction: Use AI agents to query, summarize, or generate content within your notes without leaving your local environment.
↳Project documentation: Maintain project documentation with version control (if using Git with the Forge) and easily link related information.
↳Research and learning: Clip articles, organize research notes, and leverage semantic search to quickly retrieve relevant information for studies.
brain.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.
