Shuttle Went Multiplayer

Shuttle is an app for exploring ideas in two dimensions — Threads carry the sequential flow, depth links let you dive deeper and surface back. Your documents are Looms, their chapters are Threads, and every bullet is a Node.

Recently, all of that learned to travel: across your devices, and to other people. Everything below is live today at wwwshuttle.app.

Sync My Devices

Your whole workspace, live on every device. Edit on your laptop, glance at your phone — changes appear within moments, in both directions.

No account, no email, no password. Your first device creates the sync room; others join with a link or QR code. Behind the scenes each device carries its own cryptographic identity, so there's nothing to sign up for and nothing to leak.

Offline is a first-class citizen: edits made on the train queue quietly and reconcile when you're back. A crash or a dead battery never costs you a change.

Share This Loom Live

Share a single Loom — just that one document — live with another person. They see your edits as you make them, and they can edit too. The rest of your workspace stays private.

The other person gets a link; when they accept, an Open button takes them straight into the shared Loom. Two commands, two very different things: “Sync My Devices” is all your stuff on your devices; “Share This Loom Live” is one document with other people.

You Stay in Control

The owner of a shared Loom can revoke someone's access, or freeze them to read-only, at any moment. It's enforced by the server and takes effect immediately — not just hidden in the interface.

Identity Without Accounts

No signup, no password, no email — your device is your identity. Each device carries its own cryptographic identity, created quietly the first time it's needed and stored only on that device.

Joining a room means answering a signed challenge: the room learns your public-key fingerprint, and nothing else about you.

Undo That Survives Collaboration

While a collaborator's edits stream in, Cmd+Z still does exactly what you expect: it undoes your last change — never theirs — and never corrupts the shared document. Most collaborative editors get this wrong; Shuttle keeps a private history of your own edits on your device, so undo and redo stay yours.

Images That Don't Weigh You Down

Paste images straight into a node. The bytes live in dedicated blob storage rather than inside the database or the sync stream, so an image-heavy Loom syncs just as fast as a text-only one.

Snapshot Sharing

Sometimes you don't want a live document — you want to hand someone a frozen copy. Share a read-only snapshot of a Loom, or of your whole workspace, as a short link that expires after a time you choose (up to 30 days; 7 by default).

Live sharing is a conversation; a snapshot is a photograph. Both are one command away.
