The short version

  • Each has a real cost: Smartcat smartwords are consumed as source words multiplied by target languages, so a product going from five to ten locales doubles consumption on identical source content and the plan you sized last year no longer fits.; Unbabel the attractive low per-word rate requires a minimum annual commitment reported around $120,000, which prices out most small and mid-sized businesses.
  • They diverge on capability: Smartcat covers Smartword allowance, Unbabel covers Machine translation with human post-editing.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Smartcat

  • Smartwords are consumed as source words multiplied by target languages, so a product going from five to ten locales doubles consumption on identical source content and the plan you sized last year no longer fits.
  • The gap between the entry tier at 1,200 USD a year and the next at 24,000 is twentyfold with nothing between them, so a team that outgrows Adapt faces a step change rather than an increase.
  • Subscription Smartwords expire at renewal and monthly plan credits expire each cycle, so unused allowance is lost rather than banked and overbuying is a straight write-off.
  • Marketplace access, the reason many buyers choose Smartcat at all, does not exist on the entry plan, and API access with single sign-on only appears two tiers up at 60,000 USD a year.
  • The published commission table in the help centre still names retired plan tiers, so the rates a buyer would use to model marketplace cost cannot be reliably mapped onto the plans actually on sale.

Unbabel

  • The attractive low per-word rate requires a minimum annual commitment reported around $120,000, which prices out most small and mid-sized businesses.
  • It should not be compared directly to per-character machine translation APIs, since the pricing unit, inclusion of human review and use case are all different, and doing so understates the real cost.
  • Turnaround time is inherently slower than pure machine translation, since human post-editors are part of the pipeline, which matters for real-time chat use cases.
  • Public pricing detail is limited outside the enterprise tier, so smaller buyers get little transparency into what they would actually pay before a sales conversation.
  • Quality and turnaround depend partly on the availability of the human post-editor network for a given language pair, which can vary for less common languages.

Answered from the vendors’ own pages

Smartcat: What is a Smartword?

A credit. One Smartword is consumed per source word per target language, so 1,000 words into five languages costs 5,000 Smartwords. AI dubbing costs ten Smartwords per dubbed word.

Unbabel: Is Unbabel comparable to Google Translate’s API on price?

No, they are different products: Unbabel is a managed service billed per word with human post-editing included, while Google’s API is raw machine translation billed per character.

Smartcat: Does Smartcat take a cut from freelancers?

No. The vendor states it does not deduct a platform commission from supplier earnings; the marketplace commission is charged to the client. Freelancers pay withdrawal fees, a fixed one to ten dollars plus half a percent, and a two and a half percent currency conversion markup.

Unbabel: What is the minimum commitment?

Enterprise pricing has been reported as requiring a minimum annual commitment around $120,000, which is a meaningful barrier for smaller buyers.

Smartcat: Is there a free plan?

No. There is a fifteen day trial of the full platform. A legacy free tier still appears in help articles but is not on the current pricing page.

Unbabel: Does Unbabel offer fully human translation?

Yes, alongside raw machine translation and MT-plus-post-edit tiers, priced differently by the level of human involvement.

Smartcat: What happens if I do not review delivered work?

After fifteen days the system verifies the work automatically and triggers supplier payment, so silence is treated as acceptance.
