What is Sonix?

Sonix turns audio and video files into accurate, timestamped transcripts in minutes. It supports over 54 languages and identifies speakers automatically, so you know who said what. You can also upload documents to the same workspace and search or ask questions across all your files.

To get started, you upload any audio or video file. Sonix processes it and gives you a transcript you can edit. Then you can add documents, generate summaries, detect sentiment, and ask questions across folders of transcripts to uncover insights.

It suits media companies, researchers, legal teams, and healthcare organizations that need reliable speech-to-text at scale. The platform is SOC 2 Type II and HIPAA-compliant, with AES-256 encryption and a zero-training policy on your data. Sonix also integrates with tools like Zoom, Teams, Zapier, and Adobe Premiere.
