Obius — Notes that evolve.
Designed for the way you think.
Your ideas don't arrive in straight lines. Obius is a visual workspace where notes carry color, ideas connect to each other, and what you wrote yesterday folds into what you're building today.
Built for founders, PMs, designers, researchers — and anyone who outgrew Apple Notes but never quite fit into Notion.
LOOPS — WRITE ONCE, REUSE EVERYWHERE
Drop a Loop into any note — a named, reusable content block like @launch_checklist or @weekly_review. Edit it in one place, every copy updates instantly. Perfect for running lists, shared context, and anything you reference more than once.
SECTIONS THAT CARRY MEANING
Every section has an intent — a color that tells you at a glance what kind of thinking lives there. Open ideas, questions you're sitting with, work in motion, issues to fix, things that are done. Five colors. Five intents. Your thinking, visible.
— Drag and drop to reorder
— Collapse, expand, and nest sections
— Rich content: text, checklists, code, quotes, images, audio
— Tap once to change a section's intent
ECHOES — REMINDERS THAT BRING THE NOTE BACK
Attach a time-based reminder to any Loop. Unlike calendar pings, an Echo resurfaces the full note when the moment matters — with all its context intact, not a one-line nag.
OBIUS INTELLIGENCE
AI that lives inside the workspace, not in another tab.
— Generate full pages from a single prompt
— Edit, rewrite, and refine content in place — no copy-pasting between apps
— Smart titles that actually describe the page
— Semantic search that finds ideas, not just keywords
— Research context: pull what you need, paste, and think from there
INSIGHTS THAT SURFACE WHAT MATTERS
Obius watches your pages for patterns so you don't have to. Cleanup suggestions, related notes you forgot about, lists hiding in your text, and safety flags for leaked credentials or secrets.
VERSION HISTORY, BUILT IN
Every note quietly snapshots itself. Browse the timeline, restore any earlier version, watch your thinking evolve over time. No save button. No lost work.
SHARE LIVE OR FROZEN
Generate a short public link to share a live note that updates as you edit — or freeze a snapshot in time. Readable URLs. View counts. Comments optional.
CALENDAR
See your work across time. Plan ahead, look back, stay oriented — without leaving Obius.
LOCAL-FIRST. PRIVATE BY DEFAULT.
— Pages stored on your device first
— Works fully offline; syncs when you reconnect
— End-to-end encrypted sync
— No tracking. No selling data. Not now, not ever.
— Optional local-only mode for maximum privacy
YOUR MIND. YOUR ARCHITECTURE.
Obius isn't another notes app. It's a workspace shaped like thinking — simple enough to start in seconds, deep enough to grow with how you actually work.
Designed for the way you think.

Ratings & Reviews
• Friendlier onboarding: founder letter, demo pages, and a starter Personal project
• AI workspace confirms layout before generating; Echo alerts are now time-sensitive
• Smoother iOS editing — momentum scroll, drag-to-reorder, unified keyboard toolbar
• Power Pack is now a one-time purchase, plus sync, share, and section-delete fixes
