Beta use

The site is intended for learning Vietnamese. Some dictionary, game, study, and AI features are still being improved and may change.

Vocabulary explanations, generated exercises, and AI responses can contain mistakes or unnatural wording. Please use them as learning support, not as official advice.

Vocabulary sources, license, and AI-assisted text

Some vocabulary pages, feature cards, quizzes, and problem sets may include definitions, examples, translations, or prompts edited, translated, or summarized by goigoi from content by Wiktionary contributors.

Applicable third-party-derived text is available under Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0). goigoi may edit, translate, summarize, or reorganize that text.

Chinese-character and chữ Nôm forms are reference displays. Some are source-aligned for the whole word; others are assembled from per-syllable character mappings and are not necessarily the only or official spelling.

Some meanings, translations, examples, or learning prompts may be generated or edited with AI assistance. Mistakes, omissions, or awkward phrasing may remain.

• Paid features are not offered unless a page clearly says so.
• If account or paid features are added later, the terms and privacy information will be updated.
