A multilingual quality partner for AI teams

We don't build AI models. We make the ones you build better in every language.

For years, Rolling Translations has reviewed, adapted and quality-checked language for government agencies, media companies and global brands. Today we bring that same linguistic rigor to AI: professional, native-speaker linguists who can tell when a response is technically correct but sounds wrong — and explain why.

Whether you're training, fine-tuning or launching a multilingual product, we give you the human judgment that automated metrics miss.

What we do

Multilingual AI Response Evaluation

Human review of AI-generated responses for linguistic accuracy, fluency, cultural appropriateness and instruction-following. Our linguists rate and compare model responses against your guidelines, flag errors, and write clear rationales your team can act on.

  • Accuracy, grammar and fluency scoring
  • Cultural and regional appropriateness
  • Instruction-following and tone adherence
  • Side-by-side response comparison and ranking
  • Written rationales and error categorization

Linguistic Data Annotation

Text classification, intent labeling, sentiment annotation and multilingual dataset review. Clean, consistent labels start with annotators who truly understand the language — including slang, idioms and context that change meaning.

  • Text and topic classification
  • Intent and entity labeling
  • Sentiment and tone annotation
  • Multilingual dataset review and cleanup
  • Guideline-based consistency checks

AI-Generated Content Quality Assurance

Reviewing and correcting machine-generated translations and multilingual content. We apply the same QA standards we use for human translation to content produced by AI, so it's ready for real audiences.

  • Machine translation post-editing (light and full)
  • Terminology and style-guide compliance
  • Error tagging and quality reports
  • Review of AI-generated marketing, support and product content

Multilingual Chatbot Testing

Testing AI assistants across languages and regional variants to identify linguistic errors, inconsistencies and unnatural responses. We talk to your assistant the way your users will — and report back on where it breaks.

  • Conversational testing by native speakers
  • Regional variant coverage (e.g. Latin American vs. European Spanish)
  • Consistency, tone and persona checks
  • Edge-case and ambiguity testing
  • Structured bug reports with suggested fixes

Why AI teams work with Rolling

👩‍💼

Linguists, not crowdworkers

Every project is handled by professional, native-speaker linguists with translation and QA experience.

🏥

Subject-matter teams

Dedicated linguist teams for medical, legal, education, government, technology and marketing content — so domain-specific responses are judged by people who know the field.

🌎

Regional depth

We know that "correct Spanish" in Mexico City isn't always correct in Buenos Aires or Madrid. We test and evaluate by variant, not just by language.

✅

Built on QA

Quality assurance is the core of what we've always done. Clear criteria, consistent scoring, and reports your engineers can use.

🤖

Hands-on with AI workflows

Our team already works inside AI-enhanced language pipelines, from AI dubbing script adaptation to machine translation post-editing.

🔒

Confidential by default

Your data, prompts and model outputs are handled under strict confidentiality.

How we work

1

Scope

We review your use case, languages, guidelines and volumes.

2

Pilot

We run a small calibration batch so you can check quality and alignment before scaling.

3

Scale

We assign a dedicated linguist team per language and domain, with ongoing QA.

4

Report

You get structured results, error trends and recommendations — in the format your team uses.

Languages and variants

We support evaluation, annotation and testing across 160+ languages, with special depth in Spanish regional variants for Latin America, the U.S. and Spain. Need a language not listed? Ask us — we'll tell you honestly if we can cover it.

Frequently asked questions

Do you develop AI models?

No. We're a language services company. We provide the human linguistic expertise that helps AI teams evaluate, train and test their own models.

Can you work with our guidelines and tools?

Yes. We adapt to your rating rubrics, annotation guidelines and platforms, or we can help you define them.

Can we start with a small pilot?

Yes — we recommend it. A pilot lets you validate quality and calibration before committing to larger volumes.

How do you keep ratings consistent across linguists?

Through calibration rounds, shared guidelines, reviewer spot-checks and regular feedback loops.
