The short version

  • Only POEditor has a free tier, so it costs nothing to try first.
  • Each has a real cost: POEditor the quota counts every string on the account, including obsolete terms from retired features, so cost creeps upward unless someone deliberately prunes projects.; 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.
  • They diverge on capability: POEditor covers String based billing, Sonix covers Automated transcription.
  • 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.

POEditor

  • The quota counts every string on the account, including obsolete terms from retired features, so cost creeps upward unless someone deliberately prunes projects.
  • Several projects share one account quota, so a team can be pushed into a higher tier by work in an unrelated repository.
  • There is no in-context or visual editor, so translators guess at where a string appears and length or gender errors surface only after a build.
  • Quality assurance checks are basic compared with the larger platforms, with no configurable rule sets or enforced terminology gates.
  • The company is small, support is email based, and there is no self-hosted or on-premises option, which rules it out where data residency is contractually fixed.

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.

Answered from the vendors’ own pages

POEditor: Does it charge per translator?

No. Contributors and languages are unlimited on every plan. Only the total string count is billed.

Sonix: What does Sonix cost per hour?

$10 an hour on pay-as-you-go, and $10 an hour for any usage beyond the monthly allowance on every subscription tier. That overage rate is published, which is unusual in this market.

POEditor: Is there a free plan for open source?

Yes, open source projects can apply for a free plan, which is why many community translated applications use it.

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.

POEditor: Does it support in-context translation?

No. Translators work from the string list and any comments or screenshots you attach, not from a live preview.

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.
