AI translation quality varies by language. For widely-spoken African languages (Swahili, Afrikaans, Amharic, Zulu), quality is generally good. For less-resourced languages, the AI output may need more human editing than European languages typically require.

Colonial: English, Spanish, French, Portuguese (with regional variants for each country)
Hawaiian, Māori, Samoan, Tongan, Fijian
Lang Forge supports classical and constructed languages if you need them: Latin, Ancient Greek, Esperanto. AI translation quality for these is experimental and depends on the provider.
Lang Forge uses standard ISO 639-1 and ISO 639-2 language codes, with optional ISO 3166-1 alpha-2 country suffixes for regional variants:
en — Englishen-us — English (United States)en-gb — English (United Kingdom)de — Germande-at — German (Austria)zh-cn — Chinese (Simplified, Mainland China)zh-tw — Chinese (Traditional, Taiwan)pt-br — Portuguese (Brazil)es-mx — Spanish (Mexico)The full list of codes is visible in the Lang Forge language picker.
Based on benchmark testing, Lang Forge’s AI translation (via GPT-4o and DeepL) produces these rough quality tiers:
Tier 1 — excellent (post-edit light touch):
English ↔ German, French, Spanish, Italian, Portuguese, Dutch, Polish, Russian, Japanese, Chinese (Simplified)
Tier 2 — very good (review before publish):
Most other major European and East Asian languages, Arabic, Hebrew, Turkish, Korean, Vietnamese, Thai, Indonesian
Tier 3 — good (human review recommended):
South Asian languages, Central Asian languages, most Southeast Asian languages, widely-spoken African languages
Tier 4 — experimental:
Classical languages, constructed languages, and less-resourced regional languages
Your language switcher picks it up automatically, and your site is ready to receive translated content for the new language.
If you need a language that isn’t in the standard list, contact us. WordPress itself supports a long tail of languages and regional variants, and we can usually add anything that WordPress supports.
