Obius — Notes that evolve

Loops that sync. Echoes that remind. Nodes that progress. A visual workspace designed for the way you think. Architect your thoughts.

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.
