Universal clipboard

Like your clipboard, but across all your devices.

Copy on your phone, paste on your computer: a link, a paragraph, a file. No cables, no matching brands, no shared account.

  1. 1

    Copy

    Any device. Text, screenshots, files, anything.

  2. 2

    Paste at zas.red

    Paste on the page. No forms, no folder to choose.

  3. 3

    It is everywhere

    It appears on your other devices at once. A link passes it to anyone.

JavaScript
// split into chunks before it leaves
async function upload(file) {
  const parts = await split(file, 4 * MiB);
  return Promise.all(parts.map(send));
}

Code arrives as code: monospaced, coloured, language set.

Unlike your clipboard, the next copy does not replace it: it lives for 5 days.

The replacement

Everything you used for this.

Instead of

Emailing yourself

Send it from the phone, open it on the computer. In five days it leaves on its own.

Instead of

WhatsApp

The photo arrives with every megapixel. Pass it on with a link, and it opens without an account.

Instead of

Drive or Dropbox

They arrive, you use them, they go. In five days the list clears itself, with no folders to maintain. What you keep, you pin.

Instead of

A USB stick

Turn on Direct and the file travels device to device, encrypted. If the network requires it, Zas uses a relay. Nothing is stored unless you choose the 24-hour encrypted fallback. Both devices need Zas open.

The corridor

A corridor, not a warehouse.

Everything you send starts with a 5-segment ring, one per day. When the ring goes dark, the item deletes itself. Nothing piles up. Pin what needs to stay and its clock stops until you release it.

Day 1

just arrived

Day 3

3 left

Last day

gone tomorrow

Pinned

stays as long as you want

Always encrypted.

Zas encrypts content on your device. Storage receives encrypted bytes. The service keeps the account, channel, delivery and expiry metadata needed to sync and remove items.

Agents

Your agents send and read what you see.

Pair a coding agent with a code. It sends files and notes into the channels you allow, and reads what is there. When two of your agents share a channel, they pass work to each other and you see every item, marked as theirs.

Any MCP client can pair: Claude Code, Codex and others.

  • One code to pair

    The agent asks, you approve in Settings. Up to 5 agents on a free account.

  • Permissions per channel

    Send and read are separate switches on each channel. Turn either off at any time.

  • In plain view

    Every agent item carries an agent mark and deletes itself after one day.

  • Direct as well

    An agent can send or receive large files through Direct, without storing them.
