Overview

Vietnamese is unforgiving of the small errors AI makes constantly: it drops or misplaces the tone diacritics that change a word entirely, and it stumbles over the pronoun system, where the right term depends on age and relationship. Northern and Southern usage differ in ways a model rarely tracks, but a native speaker hears at once.

As a Vietnamese Expert, you'll judge and correct AI output in Vietnamese, teaching models to write the way people actually address one another.

What you’ll actually do

- Review translations between English and Vietnamese for meaning, tone, and the right relational pronouns.
- Score and rank model output in Vietnamese, catching wrong diacritics and phrasing that ignores who is speaking to whom.
- Write the better version when the model falls short, natural in either Northern or Southern usage.

Roles this fits Common backgrounds: Vietnamese Linguist, Bilingual Reviewer, Localization Specialist.

What we look for





- Native or near-native fluency in Vietnamese.
- Sensitivity to the pronoun system and to regional differences.
- Clear written English: your explanations are the training signal.
- No degree required. We care about what you can do, not where you learned it.
