AI translation service

Complex texts, accurately translated

Specialised content in a technical structure — that's not something you can simply run through a translator. VertaalDuo combines AI technology with human expertise to deliver translations that are accurate, careful, and structurally intact.

Problem

Standard translation tools fail with complex texts

DeepL and Google Translate do fine with simple texts. But when structure and specialisation come together, things break down. We know this problem — because we ran into it ourselves.

⚠️

Standard tools translate the code as well and break the file

Specialised content

Medical questionnaires, legal documents, IT documentation, or psychological instruments — every field has terminology that cannot simply be translated word for word. One wrong term changes the meaning.

Technical structure

Your text isn't in a Word document but in a file format with its own structure. Standard tools then also translate the markup, break the structure, or skip passages entirely.

Our approach

AI power with human craftsmanship

We don't use AI to replace the translator, but to accelerate the process. The technology does the heavy lifting; we ensure quality, and you provide the domain expertise. Together we raise the result to a higher level.

Analysis

We examine your text: what structure, what terminology, what pitfalls? Based on this, we determine the best translation strategy.

AI translation & refinement

Our AI-driven method translates the content while preserving structure. We then refine the result for accuracy and terminology.

Review & delivery

In consultation with your subject matter expert, we review the translation. Only when it's right — in structure, language, and content — is it done.

Proven results

Not new to the craft, just new as a service

VertaalDuo is new as a brand, but our methodology is not. We developed our AI-assisted approach while translating an extensive psychological questionnaire — complex in both structure and subject matter — from Dutch to English.

Structure preserved — XML markup, nested elements, and conditional logic remained intact

Turnaround shortened — what previously took weeks was completed in days

Content verified — reviewed and approved by a domain expert
