Obsidian.brain is a web-based second-brain workspace that helps users create, connect, and visualize notes as a knowledge graph.
The project is inspired by how the human brain connects ideas instead of storing information in isolated lists.
- Create, edit, and delete notes
- Add tags to notes
- Connect related notes manually
- Auto-link notes using
[[Note Title]] - View backlinks automatically
- Visual knowledge graph using SVG
- Search notes by title, content, and tags
- Markdown support
- AI-style smart suggestions based on tags and keyword similarity
- Data persistence using LocalStorage
- Clean modern dashboard UI
Traditional note-taking apps store information in a linear way.
But human thinking is non-linear and connection-based.
Users often struggle to:
- Find relationships between ideas
- Remember connected concepts
- Organize learning material visually
- Discover hidden links between notes
Obsidian.brain solves this by turning notes into a connected knowledge graph.
Each note acts as a node, and relationships between notes become edges.
Users can explore their thoughts visually, discover backlinks, and build a personal second brain.
