Quillium Omni: cloud sync across all your devices.
Real-time collaboration that just works.

No spam. You'll hear from us when Omni is ready for early testers.

What Omni adds

Two things, bundled.

Cloud sync across your devices, and real-time collaboration with other people. One subscription, both included.

Across your devices

MacBook
Studio
iPhone*

Every device, one document

Start a draft on your laptop. Edit a paragraph from your phone on the train. Pick up on your desktop at home—even mid-sentence, with your revision history intact. Omni is fast, background, and invisible.

macOS Windows Linux

*Quillium is not yet available for mobile.

Offline-first, always

Lose Wi-Fi, crash the app, yank the power: Quillium keeps going. Every keystroke lands on the device in front of you first. The cloud is just where they meet.

Offline

Saved locally · will sync when online

With other people

The lighthouse cast its beam across the water, indifferent to the storm.

Rena · editor

Can we try "swept" here? More active.

Y

You · just now

Yeah — also wondering if "storm" is too tidy.

Annotations that move in real time

Comments, suggestions, and revisions sync live, anchored to the exact words they reference.

One document · two views

You viewing

Same branches, same annotations — each of you decides which revision to look at.

Shared text, independent views

Read one revision while your friend edits another, or opt into follow mode when you actually want to sit beside them.

FAQ

When will Omni ship?

It's currently available through the waitlist!

Why is this a paid add-on?

Running a real-time relay server costs real money. We'd rather charge honestly for infrastructure than mine your data. The free app stays free because it doesn't rely on our servers.

What if I cancel?

Your documents were always stored on your local device first. Omni is only a layer on top, not a replacement.
