Stream multichat: every message and event in one feed
Koster’s multichat brings stream messages and events into one feed: in the dashboard, in its own window on a second monitor and in a widget on your OBS scene. Twitch is connected today with subs, gifts, raids, bits and channel point rewards, and YouTube and VK Video chat is in development. You can reply to viewers right there.

How it works
Log in with Twitch
Koster connects to your channel’s chat on its own, nothing to set up.
Open chat under “Live”
Messages and stream events show up in the feed right away.
Pop chat out into its own window
A window without extra panels fits nicely on a second monitor next to OBS.
What it does
Platforms
Twitch works today. YouTube and VK Video chat is in development: their messages will arrive in the same feed and the same OBS widget, marked with the platform.
Events stand out
Subs, resubs, gift subs, raids and bits look different from regular messages, so you won’t miss them in a busy chat.
Rewards with the viewer’s text
A reward comes with the viewer’s message when it asks for one. You see who redeemed what.
Reply to viewers
Write in chat from Koster as yourself without switching to the Twitch tab.
Text-to-speech in the browser
Listen to chat right in the Koster window with your choice of voice, speed and volume. For text-to-speech on stream there is an OBS widget.
The feed survives reloads
Messages from the last 30 minutes come back after a page reload.
FAQ
How is Koster multichat different from Twitch chat?
Koster puts stream events and channel point rewards in one highlighted feed, and chat opens in its own window without the player or recommendations. You can reply to viewers there too.
Can I show this chat on stream?
Yes, with the OBS chat widget. It shows the same messages on your scene in your own style.
Do I need a second monitor?
No. Chat opens in any browser window, and with a single monitor the Koster desktop overlay for Windows and macOS shows chat on top of your game.
Does the multichat work with YouTube and VK Video?
Twitch only for now. YouTube and VK Video chat is in development: their messages will arrive in the same feed and the same OBS widget.
