Product Overview & Architecture
Obsidian is the gold standard of local-first personal knowledge management (PKM). Your thoughts, research, and documentation remain 100% private and future-proof as standard text files on your local hard drive. With interactive knowledge graph visualization, bi-directional [[wikilinks]], infinite canvas boards, and an open plugin ecosystem, Obsidian is the ultimate second brain.
BEST SUITED FOR:Engineers, researchers, writers, and power thinkers who refuse proprietary cloud lock-in for their personal notes
Key Features & Capabilities
100% local-first architecture: Notes are plain Markdown (.md) files on your filesystem
Bi-directional linking with interactive 2D/3D knowledge graph visualizer
Infinite canvas workspace to arrange notes, cards, images, PDFs, and web links visually
Over 1,500 community plugins (Dataview, Excalidraw, Calendar, Kanban, Git sync)
End-to-end encrypted Obsidian Sync across macOS, Windows, Linux, iOS, and Android
Free for 100% personal use with zero artificial document or note limits
