The moment you multistream from OBS, your audience splits. Twitch is in one window, YouTube in another, Kick in a third, and TikTok on your phone. You miss questions, you answer the same thing twice, and viewers on the smaller platform feel ignored because they are.
Combining the chats fixes the reading problem twice over: once for you, in a dock inside OBS, and once for your viewers, as an overlay on the stream itself. This page is about the second one — the combined chat overlay. Both come with the same plugin, and both read from the same connections.
Most multi-chat overlays are websites. You sign in to their platform, link every account, copy a URL, paste it into OBS by hand, and go back to their site every time you want to change the font size. Many of them also want a monthly plan for it.
This one is part of an OBS plugin you already have open. The same connections that feed the Multi-Chat dock feed the overlay, so there is nothing extra to link and nothing to copy — and it costs €4.99 once, not every month.
Because this is a real OBS plugin and not a web page, it can talk to OBS directly. Press “+ Add to stream” in the Multi-Chat dock and the browser source appears in your current scene, already sized and positioned. Change the theme or the text size later and press “Apply changes” — every overlay source in every scene updates itself. No deleting, no re-adding, no fiddling with URLs.
An overlay is not a chat window with a different colour. This one is built for being on screen: transparent background, text outlined so it stays legible over bright scenes, messages that fade in and can auto-hide after a while, and a per-platform filter if you only want some chats on stream.
Three themes are included — clean text, translucent cards with a platform-coloured edge, and a compact bar for narrow strips. Twitch badges and 7TV, BTTV and FFZ emotes render inline. The CSS class names are stable, so you can restyle everything from the browser source's own Custom CSS field.
1. Install the MultiStream OBS Plugin and restart OBS. A Multi-Chat dock appears in your docks menu.
2. Open the connections panel and connect Twitch, YouTube, Kick, TikTok or X. Twitch, YouTube and Kick log in with their own buttons; for TikTok and X you paste the link of the live you are running.
3. Pick a theme and a text size, then press “+ Add to stream”. The browser source is created in your current scene, already sized and positioned.
That is the whole setup — there is no URL to generate, copy or paste. The overlay reconnects on its own, survives scene changes, and shows recent messages again immediately after OBS reloads the source, so it is never empty on camera.
The same three steps work for any combination: Twitch and Kick, Twitch and YouTube, YouTube and TikTok, or all five at once. Platforms you have not connected simply do not appear, and you can hide one from the overlay without disconnecting it using the per-platform filter.
A combined chat overlay makes most sense when you are actually live on several platforms at the same time — and that is the other half of this plugin. The same €4.99 that gives you the overlay also lets you stream to Twitch, YouTube, Kick, X and any RTMP server at once from one OBS, encoding your frames a single time.
So the two halves fit together: go live everywhere from one OBS, read all the replies in one dock, and show the merged conversation on screen so your viewers can see that the room is bigger than the platform they happen to be on. If you are still choosing how to multistream, the comparison against obs-multi-rtmp and the comparison against cloud restreaming cover that side.
People mean two different things by "combine my chats", and it is worth being explicit about which one you need.
A dock is for you. It lives inside the OBS window, nobody watching sees it, and it is where you read and reply — you can answer Twitch and Kick straight from it without alt-tabbing. An overlay is for your viewers: a browser source sitting in the scene, on top of gameplay, showing the merged conversation to everyone watching on every platform.
Most streamers want the dock for themselves and the overlay for the audience. Both are included, both read from the same connections, and turning the overlay on does not change anything about the dock.
The overlay is one part of the plugin. The same €4.99 covers multistreaming to Twitch, YouTube, Kick, X and any RTMP server at once, a vertical 9:16 output for TikTok and Shorts, the Multi-Chat dock inside OBS, and an Activity Feed with follows, subs, raids, bits and Super Chats from every platform.
The chat overlay ships in version 1.5.0 and is currently in beta: it works, but give it a test run before leaning on it in an important stream.
Install the plugin, connect your platforms in the Multi-Chat dock and press “+ Add to stream”. The browser source is created in your current scene already configured, so every platform's chat appears on screen in a single box. You can also copy the overlay URL and place it manually in any scene.
Yes. The overlay only needs the platforms you connect in the Multi-Chat dock, not the multistream outputs. If you go live on Twitch alone but keep a YouTube live running, or you only want the merged chat on screen, it works the same. Multistreaming is included in the same plugin, but the overlay does not depend on it.
The dock is a panel inside the OBS window that only you see; it is where you read every platform at once and reply to Twitch and Kick without alt-tabbing. The overlay is a browser source placed in your scene, so the merged conversation is visible to everyone watching. Both are included and both read from the same connections.
No. Because this is an OBS plugin rather than a website, pressing “+ Add to stream” creates the browser source for you. Changing the theme or the text size later updates every overlay source in every scene, with no deleting and re-adding. Copying the URL manually is still possible if you prefer to place it yourself.
Twitch, YouTube, Kick, TikTok and X (Twitter). Each message is tagged with its platform colour, and Twitch badges plus 7TV, BTTV and FFZ emotes are rendered inline.
Yes. Three built-in themes (clean text, translucent cards and a compact bar), font size in pixels, optional auto-hide of old messages, and a per-platform filter. The overlay has a transparent background and stable CSS class names, so you can also restyle it from the browser source's own Custom CSS field.
No. The overlay uses the platforms you already connected in the dock, so there is no separate site to sign up to. It is covered by the same one-time payment of €4.99, with no monthly plan and no limit on messages.
€4.99 once. Twitch, YouTube, Kick, TikTok and X in a single box. No subscription.
