NoteRich
NoteRich is a smart note-taking app built around rich editing, AI memory, and local-first privacy. Your original notes stay 100% on your device, while AI features use only minimal context temporarily, without compromising privacy. It combines Markdown and rich text in one workspace, allowing users to write polished documents or work quickly with code-friendly syntax. Notes can include tables, charts, code blocks, math formulas, Mermaid diagrams, Graphviz graphs, ECharts visualizations, attachments, and media, making NoteRich useful for research, documentation, planning, and personal knowledge management. Its AI assistant is powered by local notes and gets smarter over time, helping users scan and extract content, summarize ideas, ask questions, and generate personalized insights from their own knowledge base. NoteRich’s AI Memory transforms a passive note collection into an active, intelligent knowledge base by combining local-first privacy with retrieval-augmented generation.
