Twenty games, already in the thread
Send one from the message box and it lands in the conversation. Whoever wants to play taps in, and every result is worked out on the server — so nobody wins by editing their own screen.

Calls that sound like a room
Voice and video for two or the whole group. Share your screen, and turn your camera on or off whenever you like.
Groups you can actually run
Reports get looked at rather than filed away, and who can add you to a group is up to you.
Notified, not nagged
Push when you want it, muting per chat, and quiet hours you set once.
Find it again
Search every chat and jump to the message where it was said.
On any computer
Any modern browser — a school Chromebook, an old laptop, a gaming PC. Your chats and games follow you between them, and they work on a phone too.
Questions people ask
Is Sivo free?
Yes. Chatting, calls and all twenty games are free, with no adverts in your chats. Sivo Premium is an optional extra with a few bonuses, such as live typing.
Do I need to download anything?
No. Sivo runs in your browser, on a computer or a phone.
How do the games work?
Pick one from the message box. It sends into the chat like a message, anyone in that conversation taps to join, and it opens full screen. Games are decided on the server, so nobody can rewrite the result on their own computer.
Can I use it on more than one computer?
Yes, and at the same time. Your conversations and settings are on your account rather than on one device, so a phone and a computer show the same chats.
How old do I have to be?
Thirteen or over. Sivo asks for your birthday when you sign up.
Do I have to give a phone number?
No. An email address or a Google account is enough, and your friends add you by username.
Who can see my messages?
The people in the conversation. Reported messages are reviewed so reports can be acted on, and Sivo’s owner has safety tools for serious cases, explained in the Privacy Policy. Messages are not end-to-end encrypted. You can export or delete your account whenever you like.
That’s the bottom. Go send a game.
Sign up with your email or Google in about thirty seconds, add people by username, and send them something to play before they have picked a profile picture.
