Be in the room.

See it all. Details matter. Direct peer-to-peer on a screen that can actually do 4K and 8K.

No account required. Paste an invite code or start a call above.

Presence that fills a high-end display instead of shrinking people into a postage-stamp tile.

Video and audio travel machine to machine. No media server sits in the middle decoding your stream.

Resolution follows the hardware. Extra cameras can join as a supporting angle when the host allows — not a promised mobile or TV feature.

What no one else does

Everything runs in the browser, peer-to-peer, with nothing decoding your video in a data centre.

Optimized for the screen, camera, and network you already own. The goal is presence, not a grid of tiny tiles.

Direct peer-to-peer, no media server. A full mesh for small rooms, built for long sessions.

Insertable Streams encryption with a 4-emoji Safety Number.

Free STUN only — no TURN, no SFU, no bandwidth bills.

4K and 8K when your camera, network, and screen can deliver it. No artificial caps, and no warranty either.

Three rooms we built for first. Each one starts with the same reason.

I 4kChat because I have a business that needs to be shown — not reduced to a postage-stamp tile.

Pitches, consultations, and reviews where the other person should read as life-size, not as a thumbnail.

I 4kChat because the client and I need to judge the real feed — not a compressed proxy.

Small-shop shoots and client review where focus and colour have to survive the trip to the other end.

I 4kChat because my guest and I need to look like we share a room — and keep clean local sources.

Interviews and podcasts where the guest joins from one link and each side keeps its own file for the edit.

Free calls run at the resolution your machine and network can sustain. Upgrade for extra cameras as participants, local recording, and more.
