What is Sonix?
Sonix is a web-based platform that converts audio and video files into text using AI speech recognition, with the company stating 99% accuracy across 54+ languages. Users upload files such as MP3, WAV, MP4 or MOV, receive timestamped transcripts with speaker detection, and edit them directly in a browser editor where changes to the text also update the audio.
Beyond transcription, the platform offers AI translation of transcripts, automated frame-perfect captions and burnt-in subtitles, and AI Analysis that generates summaries, chapters and sentiment. Newer workspace features let teams upload documents alongside recordings and ask questions across all files. Collaboration includes multi-user permissions and read-only sharing, and the product lists SOC 2 Type 2 and HIPAA compliance with encrypted storage.
