Sonix
San Francisco transcription platform that converts audio and video into searchable, translated, and subtitled text.

Sonix was founded in 2017 in San Francisco by Jamie Sutherland, Stephen Hopkins, and David Dat Nguyen. The company has stayed privately held and self-funded, running with a lean team while serving a large user base across legal, media, education, and enterprise customers. The platform converts spoken audio and video into transcripts, offering automated speech recognition across more than 50 languages plus translation into a similarly wide set of target languages. Beyond raw transcripts, it generates subtitles and captions in standard formats, AI summaries and chapter breaks, and lets users edit the underlying audio by editing the transcript text directly, a workflow many podcast and video editors use to cut filler words and dead air quickly. Sonix reports millions of users across more than a hundred countries and lists organizations including Google, Adobe, The New York Times, and Stanford University among its customers. It competes directly with tools like Rev, Otter.ai, and Descript's transcription features, and has built its reputation mainly on transcription accuracy and straightforward per-minute pricing rather than a broader content or editing suite.
