The short version

  • Only Transifex has a free tier, so it costs nothing to try first.
  • Each has a real cost: Sonix monthly hour allowances are small relative to the subscription price: the $25 Core plan includes five hours, which at the published $10 overage rate means the subscription is only worth buying for storage and features rather than for the hours.; Transifex word-based scaling creates unpredictable costs beyond base subscription
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Sonix

  • Monthly hour allowances are small relative to the subscription price: the $25 Core plan includes five hours, which at the published $10 overage rate means the subscription is only worth buying for storage and features rather than for the hours.
  • Unused hours do not accumulate into a meaningful reserve, so an irregular workload of a heavy month followed by a quiet one pays overage in the first and wastes allowance in the second.
  • There is no human correction tier at self-service prices, so anyone with an accessibility or legal accuracy obligation has to add a separate supplier or a member of staff to the workflow.
  • The cited 99 percent accuracy is a best-case figure on clean single-speaker audio, and overlapping speakers, strong accents, technical vocabulary and room noise degrade it enough that editing time, not transcription cost, becomes the real expense.
  • Storage is capped per plan at 25GB to 100GB, and video files consume it fast, so long-running teams end up deleting source media or upgrading a tier for storage they do not otherwise need.

Transifex

  • Word-based scaling creates unpredictable costs beyond base subscription
  • AI words restricted to annual plans only for some tiers
  • Vague collaborator limits (10, 30, 100) with broad definitions
  • Custom Enterprise+ pricing not published
  • Separate AI words and MT words add-ons create additional costs

Sonix: Is there human transcription?

No. Sonix is automated transcription plus an editor for you to correct. If you need a contracted accuracy level, this is the wrong category of product.

Transifex: What's the starting price for a paid plan?

The Starter plan costs $160 per month USD (or $135 per month on annual billing, $1,620 per year). It includes unlimited projects, translation memory, online editor, and collaboration tools.

Source
Sonix: How accurate is it really?

The 99 percent claim assumes clean, single-speaker, standard-accent audio. Multi-speaker recordings with background noise land noticeably lower, and the cost shows up as your editing time.

Sonix: How many languages?

Transcription in over fifty languages and translation into a similar number, which is wider than most self-service competitors.
