Kibitz
Look at anything together — anywhere on the web.With anyone. Even agentic AI.
No accounts. A room is just a link — open it and you’re instantly together: video, voice and chat, straight between browsers and end-to-end encrypted, so no server can see or hear you. Then look at something together — share your screen in a click, right from the browser. How security works →
free · no signup · works on phones
Add it to your home screen so invite links open right in the app. Every room gets a private, un-guessable link — you choose who can join: anyone with the link, or only verified people or AI agents.
kibitzer (n., from Yiddish) — the one at the card table who isn’t playing: just hanging over the game, watching, chatting. Be that, anywhere on the web.
🃏 Watch an AI kibitzer join your game
Deal yourself a hand of Whist and an AI agent joins your room — it watches your cards and whispers private coaching to you, over the same end-to-end-encrypted channel, acting right in a human’s place. It enters by its own key, sees only what you let it, and never touches the table chat. No accounts, no setup — it all runs on the open Kibitz engine.

Made for side-by-side, not meetings
Pair-programming and debugging · studying together · the daily crossword or Connections · reading a recipe or article together · watching the match · keeping company while you both work.
- 🔒 End-to-end encrypted
- 🙈 No media server
- 🪪 No accounts
- 🚫 No ads or trackers
🔒 Actually private
Calls are peer-to-peer WebRTC, encrypted end to end (DTLS-SRTP). When two networks can’t connect directly, an encrypted relay forwards the call — it still can’t read it, and there’s no media server that could decode or record you.
🛡️ Nothing to subpoena
Your call is end-to-end encrypted and goes straight between browsers — no server ever holds it. So no one, including us, can be made to record, decrypt, or shut down a call in progress. We have nothing to hand over.
🔗 A link is the room
Start a room, send the URL. First to arrive opens the table; friends join from any browser. If everyone leaves, the room simply stops existing.
🤫 Polite by default
Everyone joins muted with the camera off — turn yourself on when you’re ready. Speaking lights up your tile, so the quiet ones stay comfortably quiet.
Show anything — share your screen
Share a tab or your whole screen in one click, right from the browser — no extension, nothing to install. Everyone in the room watches live, and anyone you invite can join from a plain link. The walkthrough, the spreadsheet, the recipe, the match — look at it together.
Built on an open engine — for people and AI
The same room a person joins, an AI agent joins too — over the same encrypted channel, seeing what you see and acting right beside you. It’s the same engine site owners embed in one line or drive headless to build their own thing.
