Live rooms · one code · no account

Seven characters,
and the room exists.

A room here is a code. Make one, hand the seven characters to anybody, and they are in it — up to a hundred people at once, with no account to make and nothing to install.

Words, files to 100MB, voice notes, polls and a webcam call, all in the same room. Seal it and the words are encrypted on your own device before they leave it. Thirty days after the last word the room and its files are swept.

Method

A code, a shelf, and a thirty-day clock.

A room is a code

Seven characters, minted on the wire and never guessable from the last one. Up to one hundred seats to a room. An account is optional and only keeps your name and your log — a seat survives a reload because the code is the key, not a session.

Files go up in pieces

Anything up to 100MB, sent as 4MB chunks so no single request has to be heroic. Images and movies show themselves in the room; everything else downloads. Anything a browser would execute is served as an attachment — a chat room must never become a place to host a page.

Sealed rooms seal in the browser

A sealed room encrypts with AES-GCM through the browser’s own crypto.subtle before anything is sent, so the wire holds ciphertext and nothing else. Polls seal their question and choices too, and a push nudge carries one empty tickle — never a payload, never the words.

Thirty days, then swept

A room and its files live thirty days past the last word, ninety if the host moves the KEEP dial, and then the shelf is cleared. A single line can be set to burn on its own clock — a minute, five, or an hour — and leaves blanked exactly as a redaction leaves it.
