The short version

  • Only Crowdin has a free tier, so it costs nothing to try first.
  • Each has a real cost: Crowdin pricing based on hosted words (words × target languages) makes per-unit costs variable; 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.
  • 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.

Crowdin

  • Pricing based on hosted words (words × target languages) makes per-unit costs variable
  • Individual plan pricing not published; requires contacting sales
  • 14-day trial limited to Team plan only; enterprise trial is 30 days
  • Annual billing only available for enterprise plans

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.

Source

Source
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.

Crowdin: What trial options does Crowdin offer?

Crowdin provides a 14-day free trial of the Team plan and a 30-day free trial for enterprise plans. Open source and academic licenses are also available.

Source
Sonix: How accurate is it really?

Yes, Crowdin offers a 30-day money-back guarantee if canceling within 30 days of signup. Unlimited translators and proofreaders are included on all paid plans.
