Sonix
Pick Sonix when the transcript is a working document you will correct, subtitle and hand off — the editor is the product, not the ASR. If you mainly want live meeting notes, Otter is cheaper and better suited; if the recording is legally critical, Rev's human tier is the safer route.
Pros
- The word-locked editor makes correcting a long transcript far faster than re-typing
- 50+ languages for both transcription and translation, priced at the same hourly rate
- REST API with batch processing and custom vocabulary is included with subscriptions
- SOC 2 Type II, HIPAA posture and a stated no-training policy on customer files
Cons
- Per-seat pricing at $25/mo each punishes small teams sharing one library
- Hour allowances are the real constraint; Core's 5 hrs/mo goes fast on video
- The 99% accuracy claim is vendor marketing — independent tests put it near peers, around the mid-90s
- No free plan, only a 30-minute trial
