Emailing yourself
Send it from the phone, open it on the computer. In five days it leaves on its own.
Universal clipboard
Paste into Zas, then scan the QR code on another device to open the same session. No cables or matching brands needed.
Troubleshooting a bug? Send the log, code snippet and screenshot through the same session. Share each item with a link that opens without an account.
Any device. Text, screenshots, files, anything.
Paste on the page. No forms, no folder to choose.
It appears on your other devices at once. A link passes it to anyone.
// 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 lasts 2 days without an account, or 5 days with one.
The replacement
Send it from the phone, open it on the computer. In five days it leaves on its own.
The photo arrives with every megapixel. Pass it on with a link, and it opens without an account.
They arrive, you use them, they go. In five days the list clears itself, with no folders to maintain. What you keep, you pin.
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
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.

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
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.
The agent asks, you approve in Settings. Up to 5 agents on a free account.
Send and read are separate switches on each channel. Turn either off at any time.
Every agent item carries an agent mark and deletes itself after 5 days.
An agent can send or receive large files through Direct, without storing them.
For teams
An administrator decides who sends, who receives and how much room each person has, all under the company identity.
Your logo, colour and domain on the team’s links.
Invite by work email. Each person arrives with the role you chose.
An administrator sets each member’s storage and largest Direct file.
Every administrative change keeps date, author and detail, exportable as CSV.
