Sonix and Otter.ai both transcribe speech but do different jobs. Sonix is a cloud transcription and captioning service billed per hour, leaning on accuracy (up to ~99%) plus AI analysis (sentiment, topic, entity detection) across 53 languages. Otter.ai is a cloud meeting assistant built for real-time capture and live notes across Zoom, Google Meet and Microsoft Teams, centred on three languages (en, es, fr). Pick by whether you process media files or capture live meetings.
Choose Sonix when you have audio or video files to transcribe, caption or analyse — interviews, media, multilingual content — and pay-as-you-go billing from $10/hr suits irregular volume.
Choose Otter when you mainly want hands-off meeting notes and summaries that sync with your calendar and collaboration tools, starting at ~$17/user/mo.
Both are cloud-only, so neither suits audio that must stay on your own infrastructure. If privacy or compliance matters, see the best on-prem transcription ranking and the on-prem vs cloud transcription guide.
