Sonix, operating since 2017, focuses specifically on transcription and subtitling for video rather than broader audio editing or production. Its browser-based editor follows a text-first approach similar in spirit to Descript, edit the transcript text and the underlying timing adjusts, but Sonix stays scoped to transcription and captions rather than expanding into full audio and video editing.
Strong multi-language support is a specific strength: transcription and translation span a wide range of languages, useful for media companies and research teams working with non-English source audio or needing translated subtitle exports for international distribution. Export formats cover the specific subtitle standards video platforms and broadcasters require.
There's no free tier; pricing starts around $10 a month based on transcription minutes. For a video production or research team that specifically needs accurate multi-language transcription and broadcast-ready subtitles, rather than a general-purpose audio and video editor, Sonix's narrower scope keeps it focused on doing that one job well.
