Human quality assurance. Because “good enough” just isn’t good enough

A single wrong word can have major consequences for the customer experience, your brand or your business. Our human quality assurance ensures AI translation is safe to scale.

Why human quality review is still needed

The example of the knitting pattern reveals why human quality review is still necessary. When AI was tasked with translating the Swedish word "varv” into German, it lacked the local context and understanding required to choose the correct term between knitting in the round or knitting back and forth. The result was an inaccurate translation in this particular case.

These are exactly the kinds of nuances that human language reviewers catch. AI can work quickly and efficiently, and both prompts and glossaries can be improved over time. And yet, when large volumes of content are translated, small errors can quickly accumulate to tarnish the work and impact the customer experience and brand. That’s why human-led quality review is still an important part of the process.

Light proofreading

A quick human check of grammar, consistency and obvious errors. Ideal for high-volume content where AI quality is generally high, but where a final human pass adds extra peace of mind.

Full post-editing

A thorough human review and refinement of AI-generated content — with adjustments to language, tone and terminology. This is our most popular QA level for product descriptions and
marketing content.

Localisation review

Alongside linguistic accuracy, we also ensure the content is localised to a particular market. Does the material resonate and connect with the target audience? Are idioms, references and tone of voice properly adapted to the culture?

Our linguists always work in their native language and have a thorough and deep understanding of the markets they cover.

Improving AI prompts through feedback loops

Our QA doesn’t just correct errors — it also helps improve the AI workflow over time. Our linguists identify recurring patterns and help refine glossaries, tone of voice and Lexi prompts.

As a result, every review iteratively improves the system.

How it works

1. Content is translated with AI via your
configured Lexi solution.

2. The content is flagged and categorised for
human review.

3. A specialist reviewer checks, comments and corrects.

4. The feedback is structured and used to improve the AI prompts.

5. Quality improves step by step, without you having to do a thing.
