The honest brief

DeepL

  • Developer API for app integration
  • DeepL Write for editing
  • Broad app coverage
  • Next-gen model is paid-only
  • Fewer languages than Google
  • Not a general assistant

Smartcat

Bundles AI translation with a 500k-linguist marketplace and native vendor billing, so sourcing and paying humans stays in-tool.

  • Integrated linguist marketplace + payments
  • 280+ languages, translation memory
  • AI translation plus human review
  • Collaborative project management
  • Marketplace pricing varies by linguist
  • Less developer/API-first than rivals
  • Can be complex for simple jobs
