Overview

NoteRich is a browser-based, offline-first note-taking application designed for building a personal knowledge base, often referred to as a 'second brain.' It operates entirely within the browser, storing notes locally in IndexedDB, ensuring that user data never leaves the device. The platform emphasizes privacy, offering 100% offline storage and requiring no sign-up for its free version.

The tool integrates AI-powered RAG (Retrieval-Augmented Generation) search, which processes local notes to provide personalized insights and smart Q&A capabilities. This AI gets smarter over time by learning from the user's content, operating with ephemeral context for privacy. Users can create and edit notes using a rich text and Markdown editor, supporting advanced elements like LaTeX, Mermaid diagrams, ECharts, and multimedia attachments. For cross-device access, NoteRich utilizes direct P2P (peer-to-peer) note synchronization with AES-GCM end-to-end encryption, bypassing cloud intermediaries. The platform is optimized for managing massive libraries, supporting millions of characters per note and tens of thousands of notes per workspace, with features like encrypted exports and responsive UI across devices.
