Twitch chat reactions and what they mark in a VOD
Chat tells you where the moments are, but not all of its reactions mean the same thing. Here is what each one is actually saying, and what it implies about where a clip starts and stops.
Four kinds of reaction
Reelium reads a stream's chat replay message by message and sorts each one into at most one of four buckets: laughter, hype, surprise, or emotional. A message that carries two — someone posting a laugh emote and a hype emote together — is counted once, under whichever comes first in that order, so a mixed reaction cannot be double-counted into looking bigger than it was.
What matters for finding a clip is that the four behave completely differently in time. Laughter and hype spike on impact and decay in seconds. Surprise splits: some of it is a sharp shock, and some of it is tension that runs for minutes. Emotional reactions are the slowest and the rarest. Reading a chat replay as one undifferentiated “chat popped off” line throws away most of that.
Two other things are worth knowing before you trust a spike. A window is read on its strongest single category rather than on the sum of all four, so a burst of concentrated laughter is not diluted by whatever else chat was doing. And the number of distinct people posting matters: one account posting the same line thirty times is discounted against thirty people posting once.

Where this fits
Chat reactions are one input among several. Reelium also reads the clips your viewers made themselves, the transcript, and enough scene context to keep a moment intelligible once it is cut away from the stream around it. If you mostly stream Just Chatting, IRL or variety, where there is no scoreboard to key off, the variety streamer page covers how that works in more detail. If you are trying to work out how many clips a given stream is likely to yield, the clips per stream calculator is a rougher but faster answer.
Reelium reads the chat replay for a finished Twitch stream and ranks the moments, with the reason for each pick written out. You keep, drop or re-trim them before anything is exported.
