Same Wi-Fi. The screen goes straight from laptop to laptop.

The screen is the point.

Video meetings put faces first and squeeze your work into a corner. A Laptop Party room gives the whole window to the screen.

No camera tiles to arrange, pin or hide
No app for viewers to download or update
No sign-up before someone can watch

Need breakout rooms or a camera grid? A video meeting tool will suit you better, and that is fine.

Three steps, and one of them is saying four numbers out loud.

Code, name, done. No download, no account, no waiting for an installer to finish.

Same table, or different time zones.

You can tell the room type from its code. Four digits is a LAN room. Eight characters is a Remote room.

Four laptops around a table, each connected straight to the presenter's laptop.

LAN / Wi-Fi rooms

7392

For when everyone is on the same network. The screen travels directly between laptops, so it stays quick and never leaves the building.

Code: 4 digits
Best for: Classrooms, offices, workshops
Quality: 360p to 1080p60

Laptops in different parts of the world, connected to the presenter through a relay.

Remote rooms

K7Q2M9AB

For when some people are somewhere else. Remote rooms add microphone audio, chat, and a knock-to-join waiting room.

Code: 8 characters
Best for: Distributed teams, online tutoring
Quality: 480p to 1080p

Made for the sessions where a meeting is too much.

Pair programming

Share one coding window in seconds. No cameras to switch on, no meeting link with a full video UI.

Tutoring and teaching

Students type a code and their name, and class starts. It works well on classroom Wi-Fi.

In-room demos

Put the demo on every laptop at the table. Nobody squints at a projector from the back row.

Small on purpose. Still has what you need.

Everything here exists to get a screen in front of people and keep it there.

Share a screen, a window, or one tab

You decide what people see, using the picker your browser already has.

Pick the quality

Drop to 360p on weak Wi-Fi, or go to 1080p at 60 frames for smooth motion.

Anyone can present

Hand the screen to someone else without ending the room.

Survives a refresh

Reload the page and you are back in the same room.

Schedule it when you need to

Plan a room ahead of time. Invites go out by email with a calendar file, and sync with Google Calendar and Outlook.

Knock before entering

In Remote rooms, the host lets each person in.

Asked before the first room.

Something else on your mind? Write to us or read the documentation.

Do guests need an account?

No. Guests open the site, type the room code and their name, and they are in. Only the host signs in, because hosts create the rooms.

Do we all have to be on the same Wi-Fi?

Only for LAN rooms, the ones with a 4-digit code. If anyone is somewhere else, start a Remote room and share its 8-character code.

Is there really no video?

There are no camera tiles. Rooms show the shared screen and nothing else. Remote rooms add microphone audio and chat so you can talk while you share.

Can more than one person share?

Yes. Anyone in the room can start sharing, so you can hand over without ending the session.

Which browsers work?

Current versions of Chrome, Edge, Firefox and Safari. There is nothing to download.
