Sonix

Sonix is a web-based platform that converts audio and video files into text using AI, then layers translation, subtitling, and analysis tools on top of the transcript. Files are transcribed with automatic speaker identification, and the resulting text can be translated into more than 55 languages using neural machine translation while timestamps and speaker labels are preserved. The same transcripts can be turned into frame-accurate subtitles and captions for video. Beyond transcription, Sonix generates AI summaries, chapter markers, and sentiment analysis from the transcript, and includes a browser-based editor for correcting and searching text alongside the original audio or video. It offers an API and integrations with Zoom, Microsoft Teams, Adobe Premiere, and Zapier, along with multi-user collaboration and read-only sharing for teams. The company states SOC 2 Type II and HIPAA compliance, with AES-256 encryption and a policy of not training its models on customer data. Sonix, founded in 2017, is aimed at media companies, legal and healthcare organizations, researchers, and journalists who need accurate transcripts at scale, citing users including Google, Microsoft, Stanford, and The New York Times. A 30-minute free trial is available without a credit card, though exact subscription pricing beyond that trial isn't published on the page reviewed.
