Most tools ask "Where should I put this?" Obius asks "What is this, and how does it connect?"
Every page is built from nodes — discrete, meaningful units of thought instead of endless text. Each node carries a visual identity so your eyes find structure before you read a word.
Collapse what you're not working on. Expand what matters. Nest nodes to build hierarchy. The page adapts to your focus, not the other way around.
No more scrolling through walls of text to find the one thing you need. Nodes break your thinking into pieces you can see, move, and reorganize — so the structure of the page matches the structure of the idea.
When context is defined: work stays focused, ideas stay connected, decisions become clear. Obius doesn't just store information. It sharpens it.
Not a chatbot bolted on. An AI that reads your thinking and works within it.
Read, edit, and restructure your notes through natural language. The AI understands your semantic intents — it knows the difference between your ideas, your questions, and your evidence.
Smart title generation, semantic tagging, and entity extraction happen automatically. Ask it to restructure a section, surface connections, or draft new content.
50k tokens free, 500k tokens on Pro — so it's always available when you need it, without surprise costs.
The advantage is no longer access to information. It's the ability to structure it, connect it, trust it.
Define once. Reference anywhere. Always in sync.
Create a named handle — @project_goals, @key_decisions, @weekly_focus — that holds content you can reference from anywhere. Link any node in any note to a handle — it displays the content live. Edit the handle once, every linked node across every note updates instantly.
Attach time-based reminders to any handle and see them on your calendar. Set a single date or build compound schedules — every 2 days and every 3 weeks. When an echo fires, it surfaces the handle and every note that references it. Your concepts don't just sit there — they come back to you on schedule.
Your @thesis_statement exists in your research note, your outline, and your draft — and when it evolves, it evolves everywhere. No copy-paste drift. No stale versions.
Thinking is nonlinear. Your tools should be too.
Turn thoughts into verified, immutable artifacts.
Auto-saves daily snapshots of every modified note. Save a version manually anytime with a custom name.
Each version is a complete snapshot — not a diff. Full note, all nodes, all media. Compressed archives with SHA-256 integrity hashes. Human-readable IDs like OBX-A1B2-C3D4.
Browse your version history, preview any state, restore to any previous point. Ideas evolve — you should be able to see exactly how.
Share a live note (always current) or a frozen version (specific snapshot) via short URLs. View count tracking included.
Every thought can be traced, verified. A system of record for ideas. A provenance layer for decisions.
Proactive intelligence that surfaces what matters.
Detects leaked API keys, passwords, and personal data in your notes.
Discovers shared concepts between notes you didn't explicitly link.
Identifies dormant handles, nonsense content, and stale sections that need attention.
Spots list-like content that would work better as checklists.
Dashboard of reminders firing within 24 hours so nothing slips through the cracks.
Intelligence that surfaces what matters, before you ask for it.
Everything lives on-device. Cloud sync is optional.
All data stored locally on your device. Nothing leaves unless you choose.
Pro and Founding users get multi-device access. Offline-first — works without internet, syncs when connected.
Lock individual sections with Face ID or Touch ID. Your most sensitive thinking stays protected.
A trust layer for AI-assisted work. Every thought can be traced, verified, understood.
Start free. Go Pro when your system demands it.
200 founding spots at $4.99/mo — locked forever. Once they're gone, they're gone.
