Your second brain,
in the cloud.
A powerful, Obsidian-inspired knowledge management platform. Write in Markdown, connect ideas with wiki links, visualize your knowledge graph, and ask AI questions about your notes — all from your browser.
Everything you need to build your knowledge base
Powerful tools that work together seamlessly, so you can focus on what matters — your ideas.
Markdown Editor
A powerful editor with live preview, syntax highlighting, and auto-save. Write naturally in Markdown and see your formatting come alive instantly.
Wiki Links & Backlinks
Connect your ideas with [[wiki links]]. See every note that references the current one. Rename a note and watch every link update automatically.
Knowledge Graph
Visualize how your notes connect with an interactive, force-directed graph. Discover hidden relationships and navigate your knowledge visually.
AI Chat
Ask questions about your notes and get answers grounded in your own knowledge base. Powered by Claude, your AI reads across your entire vault.
Vaults & Import
Organize knowledge into separate vaults for work, personal, and research. Already use Obsidian? Import your entire vault in one click.
Real-Time Sync
Your notes sync instantly across all your devices. Every change is persisted in real time. No manual saving, no sync conflicts, ever.
Write, Link, Discover
Experience a distraction-free markdown editor with live preview that shows your formatting as you type. Headings, bold, italic, code blocks, and task lists all render inline — no toggling between modes.
Type [[ to link to any note in your vault with fuzzy autocomplete. Every link creates a bidirectional connection — see who references your note in the backlinks panel.
Rename a note, and every wiki link across your entire vault updates automatically. Your knowledge graph stays consistent, always.
See the Big Picture
Watch your knowledge come alive with an interactive force-directed graph. Every note is a node, every wiki link is a connection. The more connected a note, the larger it appears.
Click any node to open that note. Drag nodes to rearrange. Zoom and pan to explore. Your active note glows in purple so you always know where you are.
Discover unexpected connections between ideas you never thought were related. The graph reveals the hidden structure of your thinking.
Ask Your Notes Anything
Chat with an AI that has read every note in your vault. Ask questions, get summaries, find connections — all grounded in your own knowledge base, not generic internet answers.
Every answer cites the specific notes it drew from, so you can verify and dive deeper. It's like having a research assistant who knows your work inside and out.
Powered by Claude, responses stream in real time so you never have to wait. Ask follow-up questions to explore ideas further.
Based on your notes, the Zettelkasten method revolves around three core principles:
1. Atomic notes — each note captures a single idea, making it reusable across contexts.
2. Connections over categories — instead of filing notes in folders, you link related ideas using wiki links.
3. Emergence — insights emerge from the network of connections rather than top-down organization.
