The honest brief

DeepL

Specialized in-house language models, not a repurposed general LLM, prized for fluent, natural translations.

  • Translates full documents, not just text
  • 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

Smartling

Tiers content across AI Hub, AI Translation, and AI Human Translation, routing bulk copy to machines and key copy to people.

  • Enterprise TMS + AI + human network
  • Tiered quality routing
  • Strong governance and integrations
  • In-house translator network
  • Custom enterprise quotes, opaque pricing
  • Platform fee plus per-word cost
  • Overkill for small teams
