Use MonstarX in your language
In shortClick the globe at the top of any page (or go to Settings → Profile → Language) and choose one of 16 languages, each listed in its own script. Everything switches — every screen, your account and support emails, the sign-in pages, and everything the AI writes to you, from replies to the feature plan, QA reports and Ask Luna's answers. Your account remembers the choice. A new app is written in the language you use MonstarX in, unless you ask for another one.
MonstarX speaks 16 languages. Choose one and you get all of it in that language — not just the buttons, but everything the AI writes to you as well.

In Arabic, the whole of MonstarX is laid out right to left.
How do I change the language?
Section titled “How do I change the language?”-
Click the globe in the bar at the top of any page — the Projects page, Settings, a project, or the Pricing page.
-
Choose your language. Each language is listed in its own script, with its name in the current language underneath, so you can find yours even if you cannot read the current one.
-
The page reloads in the new language. On the home, Pricing, Privacy and Terms pages you go to that page’s own address in the new language instead — for example
/pricing⇄/ja/pricing⇄/ko/pricing⇄/ar/pricing.
You can also choose it in SettingsProfileLanguage, where the languages sit side by side.
What gets translated?
Section titled “What gets translated?”Everything MonstarX shows you:
- Every screen, button, tooltip and error message
- The emails about your account, plan, domains and projects, and about your support tickets and bug reports
- The sign-in and account pages
- Support: the messages when a bug report or ticket can’t be sent (for example, a file that is too large), and the labels on the Ask Luna conversation added to a ticket
Everything the AI writes to you:
- The builder’s replies and the short lines it writes between its steps
- Plan mode’s questions and the feature plan
- QA’s reports, the security and SEO/GEO reviews, and the wrap-up after a build
- The requirements brief it writes from documents you attach
- The name MonstarX gives your project
Code, file names, web addresses and names stay as they are. MonstarX checks what the AI writes before you see it, and translates any part that slipped into English.
Ask Luna answers in your language too, in writing and out loud (Chinese is spoken in Mandarin), using the names of the buttons you see, even when you ask in English. Ask Luna directly if you want another language. See Ask Luna.
This help centre is available in several languages: choose yours from the language menu at the top of any page. The help links in MonstarX open the copy in your language, or the English page when your language does not have one yet.
What language is my app written in?
Section titled “What language is my app written in?”Your app is separate from MonstarX’s own language:
- A new app is written in the language you use MonstarX in — its pages, buttons and text — until you ask for another language. Use MonstarX in Japanese and a new app is in Japanese; use it in Korean and it is in Korean. An app in Arabic is laid out right to left.
- An existing app stays in the language it already uses.
- You can always ask. For example: “Make the app English” or “Add a Japanese version of every page”.
SEO suggestions for your app (page titles, descriptions, FAQ) follow your app’s language, not MonstarX’s.
Where is my choice kept?
Section titled “Where is my choice kept?”In your account and in your browser. Your account wins, so any computer you sign in on opens in your language. If you chose a language before you had an account, MonstarX keeps it when you sign up.
Before you choose, MonstarX picks for you: your browser’s or computer’s language when it is one MonstarX speaks other than English; otherwise the language of the country you are in — Japanese in Japan, Brazilian Portuguese in Brazil, Simplified Chinese in mainland China, Bangla in Bangladesh, Thai in Thailand, Indonesian in Indonesia, Malay in Malaysia, Korean in South Korea, Vietnamese in Vietnam, Russian in Russia, and Arabic in Saudi Arabia, Egypt, the United Arab Emirates, Jordan, Kuwait, Qatar, Bahrain and Oman; English otherwise. Hindi, Tamil, Swahili and Hausa are never guessed from the country, because India, Nigeria and East Africa have several widely used languages: set your browser to yours or choose it with the globe. A browser set to the Portuguese of Portugal does not count as Brazilian Portuguese, and one set to Traditional Chinese (Taiwan, Hong Kong or Macau) does not count as Simplified Chinese. Choosing with the globe always overrides that guess.
Is there a website in my language?
Section titled “Is there a website in my language?”Yes. The home page, Pricing, Privacy and Terms have an address in every language, under the language’s code from the table above — /ja/, /ko/ and /ar/ are home pages, and /ja/pricing, /ko/pricing and /ar/pricing their Pricing pages. If MonstarX knows you read one of those languages, opening the English address takes you to the one in your language. An address with a language code always shows that language, so you can share it with anyone.
Frequently asked questions
Section titled “Frequently asked questions”Which languages does MonstarX support?
Sixteen: English, Japanese, Brazilian Portuguese, Simplified Chinese, Bangla, Thai, Indonesian, Malay, Korean, Vietnamese, Hindi, Tamil, Russian, Arabic, Swahili and Hausa. Choose yours from the globe at the top of any page. Screens, account emails, sign-in and everything the AI writes switch to that language.
Can I build an English app while using MonstarX in Japanese?
Yes. Ask for it — for example "Write the app in English". An app you already have keeps its own language.
Why did MonstarX open in another language when I never chose it?
Your browser or computer is set to that language, or you are in a country where MonstarX guesses it — Japan, Brazil, Korea or Saudi Arabia, for example. Choose English from the globe and MonstarX remembers it.
Why did the page reload when I changed language?
Everything on the page, including dates and the sign-in screens, is made in your language from the start, so MonstarX reloads the page to show it.
Which other languages are coming?
Today MonstarX offers the 16 languages in the table above. More languages can be added; watch What's new.
