Whose Restream account is it?
Yours. Restream is the fan-out and it is their product on their plan. I set it up inside your account and point your OBS at it. How many platforms you can hit at once is set by the Restream plan you choose, not by me.
What does TikTok need?
LIVE access on your TikTok account, which TikTok grants, not me. The chat reader uses an unofficial connector that can break when TikTok changes its side. There is no way to write replies into TikTok chat, so replies to TikTok viewers are spoken on air.
What about Facebook?
Facebook Live goes out through Restream to your profile or your Page. Facebook does not expose live comments on either, so Facebook chat is not in the merged rail automatically. LinkedIn and X ride Restream the same way, and X live needs a Premium account.
What does YouTube need?
A YouTube Data API key on your Google account for reading chat, and a one-time OAuth grant if you want replies written into YouTube's own chat column. YouTube's daily quota is finite, so write-backs are capped per run.
What machine and software?
OBS Studio 28 or newer with the built-in websocket on. Windows for the process-priority manager and the one-button check. A local transcription install for captions, so no audio leaves your machine. A voice service such as ElevenLabs only if you want spoken replies; the cards on screen need no voice at all.
Can it show how much someone tipped?
No. The card shows a first name and the platform. The amount is never rendered or spoken, and that is enforced in the code.
What is not included?
Restream, YouTube, TikTok and voice-service fees, which are on your accounts. Cameras, mic and lights. A Discord room with a stage and a live-chat channel, which is The Room. Both, wired and run together, is the studio solution.
