What Makes a Caption Tool Good for Streaming

Generic transcription tools are not built for streaming. You need: sub-500ms latency (generic tools run 2-5 seconds behind), gaming vocabulary support (game names, slang, and fast speech), OBS browser source compatibility, and multilingual translation. Most tools fail on at least two of these.
