Lumina-Note

Lumina Note is a free, open-source, local-first Markdown note-taking application for Windows, macOS, and Linux. It stores notes as ordinary Markdown files that remain accessible outside the application. Its editor supports live preview, reading mode, bidirectional links, and knowledge graph visualization. Users can organize interconnected information through WikiLinks, backlinks, and linked documents. PDF reading, annotations, images, and flashcards expand its knowledge management capabilities. An integrated AI agent can create, summarize, reorganize, and connect notes across an entire vault with user permission. Supported AI providers include OpenAI, Claude, Gemini, DeepSeek, and local Ollama models. Custom commands, agent skills, and experimental plugins allow users to extend its functionality.
