Hello8 vs Sonix

Hello8

Hello8 sits between raw auto-captioning and a localisation agency: machine transcription and translation, followed by an AI pass that points at the lines most likely to be wrong so an editor only reviews those. That is a real time saver for teams that already check subtitles by hand, and the European hosting suits EU buyers. The catch is cost: the reviewer bills five credits a minute, so a reviewed hour of video eats most of a Starter allowance.

Pros

• +AI Reviewer comments on likely errors line by line, with one-click accept or dismiss
• +90-plus languages for transcription and translation
• +Exports SRT, VTT, ASS, TXT or an MP4 with burned-in subtitles
• +Optional linguist review when a file must be right
• +Data processed on European cloud infrastructure under GDPR terms

Cons

• −The AI Reviewer costs 5 credits per minute, so reviewed video burns credits six times faster than transcription alone
• −Video-length caps per plan: 5 minutes free, 30 minutes on Starter
• −Prices quoted in euros only, so the dollar cost moves with the exchange rate

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
