NoteRich is a free, offline-first note-taking app that runs entirely in the browser, storing notes locally in IndexedDB so data never leaves the device. It offers a rich text and Markdown editor with LaTeX, Mermaid diagrams, and ECharts, plus AI-powered RAG search over a local knowledge base. Notes can be synced across devices via direct peer-to-peer connections with AES-GCM encryption, without relying on cloud servers.
