Overview
Sonix is an automated transcription platform aimed at teams and individuals who need fast, accurate text from meetings, interviews, podcasts, and video — not a human transcription agency. It uses speech recognition that reaches up to 99% accuracy on clean audio, automatically detects and labels multiple speakers, and timestamps every word so you can click a phrase and jump to that moment in the media. The standout workflow is the in-browser editor stitched to your audio: you correct transcripts inline while listening, then export to Word, PDF, SRT, VTT, and 30+ other formats. Sonix also translates into 40+ languages with a side-by-side editor, which is useful for global teams and subtitled video. It is SOC 2 Type 2 audited with AES-256 encryption, and a Medical Enterprise tier supports HIPAA/BAA for sensitive research. Pricing is duration-based (per audio hour), not per minute of effort, so a one-hour file costs the same whether it takes five minutes or an hour to process.

Comparison
vs. AssemblyAI: AssemblyAI is the developer-first API for building transcription into apps; Sonix is the finished product with editor, translation, and subtitles out of the box. vs. Deepgram: Deepgram wins on ultra-low-cost, high-volume API transcription; Sonix adds a polished human review editor and translation that developers would otherwise build themselves. vs. Otter.ai: Otter centers on live meeting notes and collaboration; Sonix is stronger for file-based transcription, translation, and subtitle export.
