Every serious streamer hits the same wall: one great show that deserves an audience on every platform at once. Twitch on the big screen, a vertical cut on TikTok, a lean feed for YouTube. Aitum pulls all of it into a single, comfortable control surface, so you stop babysitting four tools and start actually streaming.
Aitum multistream is a free plugin that pipes your OBS output to several destinations at once, straight from your own machine. There is no cloud relay sitting in the middle and nobody else deciding your bitrate. You keep control of the encoder and audio tracks for every output, so a sharp YouTube feed and a leaner Twitch feed sit side by side without dragging each other down.
Most relay services hide a catch in the fine print. Free tiers cap your resolution and framerate, and they often lock each platform to the lowest common quality. Aitum multistream refuses that trade. Every destination keeps its own ceiling, which means fewer upload stalls, cleaner audio routing, and a setup that scales politely when you bolt on another service next month.
Most new viewers arrive through a phone these days. TikTok, YouTube Shorts, Instagram Reels and mobile live formats all want a 9:16 frame, and cramming a landscape scene into that narrow box never looks good. Aitum vertical gives you a dedicated canvas inside OBS built solely for that tall, portrait layout, so you stop guessing and finally look native on every screen.
Instead of running two messy scene collections by hand, Aitum vertical binds them together. When you cut to your camera scene on the main canvas, the matching portrait scene follows without a thought. The result is a broadcast that looks deliberate on a television and a phone alike, never like a cropped afterthought in the corner.
Aitum TV turns a spare tablet, touch monitor or phone into a proper control surface. Trigger scene swaps, fire hotkeys, nudge audio, and fire whole actions from a grid of buttons you arrange yourself. If you have ever eyed a stream deck or a desktop companion for this kind of duty, this is the same job done tidily, only it stays glued to the wider Aitum family instead of living in its own isolated corner.
Drop a button down, point it at an action, and you are mostly finished. There is no scripting rabbit hole involved. Because it speaks to your OBS scenes directly, a single press can fire off a chain of changes that used to demand three or four separate clicks mid-stream, exactly the kind of relief a busy creator needs during a live show.
The Aitum vertical plugin drops into OBS with remarkably little friction. Install the package, restart OBS, and a clean vertical canvas appears right beside your usual one. From there you add services, pick encoders, and begin routing a genuine portrait feed to TikTok, Instagram, YouTube and more within a few clicks.
Pair your landscape scene list with its portrait counterpart once, and changes flow between them automatically. This is the step that turns a messy double layout into one cohesive broadcast, and it is the reason most people keep the vertical plugin around after the very first test run.
Plenty of creators mix live and pre-recorded output. Record a clean short while the main broadcast keeps running, push separate overlays to each format, and keep your audio exactly where it belongs. The vertical plugin exists to delete the busywork, no matter how many platforms you juggle in a single evening.
I dropped my relay subscription the week I installed it. The quality jump on YouTube is night and day.
Running a proper vertical feed without a second PC felt impossible before. Now it just works.
My whole desk now fits on one tablet. It feels like a real production room.
Yes. The multistream and vertical plugins are free, and the core tools ship a generous free tier. There are no hidden charges that quietly appear on your card at the end of a long setup day.
Not a monster, no. Your GPU and your upload connection are the real stars. Since there is no cloud relay, each added output eats a little bandwidth and CPU, so a stable connection and a mid-range computer handle a few extra destinations comfortably.
Not at all. You can send your tall canvas to TikTok, Instagram, YouTube Shorts, and many other services. The entire point is that every platform that loves a phone-shaped frame can get one without a messy repackage.
An ordinary soundboard gives you one angle. Aitum TV is built as a touch-driven console, designed to be read at a glance while your eyes stay on the game or the chat. It feeds off the same command engine as the rest of the tools, staying truly portable in the process.
You will want a reasonably current version. It ships tested against modern releases, so keeping the streaming software updated is the simplest way to avoid the odd layout or missing menu that older builds sometimes cause.
Grab the free plugins and turn one great stream into a full broadcast across every corner of the internet.
