How Hosiqo compares and tests toolsFinal recommendation
Shortlist Felo Subtitles when following and translating multilingual video meetings on zoom, google meet, teams, or webex in real time matters most, and SyncWords when delivering accessible, fcc-compliant live captions for a broadcast matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Felo Subtitles, made by Felo Inc. (Sparticle), is a real-time transcription and translation tool delivered as a Chrome/Edge browser extension plus companion desktop apps for Windows and macOS.

It recognizes speech in roughly 23 languages and translates into about 20 target languages.
