The short version

  • Only Hedra has a free tier, so it costs nothing to try first.
  • Each has a real cost: Hedra free tier limited to watermarked outputs; 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: Hedra covers Creative Studio agent, 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.

Hedra

  • Free tier limited to watermarked outputs
  • Monthly credits reset each billing cycle and do not carry over
  • Enterprise tier requires custom quote and negotiation
  • Documentation and tutorials limited on main site
  • Pricing starts at $15/month for basic commercial 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.

Answered from the vendors’ own pages

Hedra: What is the difference between monthly subscription credits and purchased credit packs?

Monthly subscription credits reset each billing cycle, while purchased credit packs do not expire between billing cycles and carry over.

Source
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.

Hedra: Can I use Hedra content commercially on free and paid plans?

Commercial use is permitted on Basic, Creator, and Professional plans. The free tier produces watermarked outputs.

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.

Hedra: What support is included with different Hedra plans?

Basic, Creator, and Professional plans have standard support. Enterprise plans include dedicated technical support via Slack and a dedicated account manager.

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.
