Aitum is the advanced multistream tool for streamers running complex setups: per-platform scene customization, per-platform audio routing, per-platform overlay differences, and platform-specific content adjustments. Aitum gives you the control that Restream and Streamlabs Multistream do not.

The advanced use case: streaming the same broadcast to a SFW-friendly platform like YouTube and an adult-vertical platform like LiveJasmine simultaneously, with different scenes, different overlays, and different audio routing for each. Aitum lets you configure the per-platform differences without running two separate streaming sessions.

The setup complexity: Aitum has a steeper configuration learning curve than Restream or Streamlabs Multistream. The payoff is full control over what each platform's audience sees and hears, which matters for streamers running cross-vertical broadcasts.

The tool is paid (subscription tier) and runs as a companion app alongside OBS or Streamlabs. The streamers who need it know they need it. Streamers running standard cross-platform broadcasts with no per-platform differentiation should default to Restream or Streamlabs Multistream first.
