Multilingual AI website builder
Build the website in the language your customers read
A multilingual AI website builder lets you describe a business in one supported language and create the finished website for readers in another. Casel keeps prompt language and website language separate, so a founder can think naturally, preserve business context, and produce responsive website copy for the audience they actually serve.
Your first build starts with a useful sentence, not a template hunt.
Why this works
A better starting point for a real business.
- Prompt in English, German, Spanish, French, Hindi, Indonesian, Japanese, Korean, Malay, Tamil, or Simplified Chinese.
- Choose the finished website language independently from the prompt language.
- Preserve business names and protected phrases instead of translating them blindly.
- Use typography and spacing appropriate to Latin, Devanagari, Tamil, and CJK scripts.
- Review the complete responsive page and request focused changes in ordinary language.

“जयपुर का एक हस्तनिर्मित सिरेमिक स्टूडियो जो दुनिया भर में भेजता है”

Spanish website copy written for local patients rather than translated button by button.

“京都の小さな旅館。静かな滞在と地域の朝食を大切にしています。”
A Japanese-first hospitality direction with appropriate hierarchy, line length, and density.
How it works
From a natural description to a website worth reviewing.
Step 1
Explain the business naturally
Use whichever supported language lets you describe the offer, audience, place, and personality with the most useful detail.
Step 2
Choose who will read the website
Select the website language from the customers you need to reach, not from the language you happened to type.
Step 3
Generate native page direction
Casel writes the hierarchy, copy, calls to action, and responsive visual direction for the chosen audience and script.
Step 4
Review with a fluent reader
Check names, market terminology, tone, cultural assumptions, and the customer action before treating any generated copy as final.
What is included
A complete first website direction.
- 11 supported prompt and website languages
- Separate prompt-language and output-language choices
- Responsive website copy, hierarchy, and visual direction
- Script-aware typography and mobile review
- Protected business names and phrases
- Plain-language follow-up changes
What is not included
Know the current limits before you start.
- Casel creates one primary website language per build; a complete multi-locale website still requires reviewed pages and stable locale URLs for every market.
- Generated wording needs review by someone who understands the language, business, and local market.
- Publishing, hosting, custom domains, direct code editing, and code export are not included in the current V1 preview offer.
- Language support does not replace legal, medical, financial, or regulated-industry review.
Compare the workflow
Choose the approach that matches the actual job.
| Workflow | What it does | Question to verify |
|---|---|---|
| Language-first generation | Creates for the chosen audience while keeping the original brief as context | Can prompt and website languages be selected separately? |
| Machine translation | Converts existing copy after the page has been designed | Are tone, layout, and calls to action reviewed for the market? |
| Localization management | Maintains multiple published locale versions and translation workflows | Does each language get a crawlable URL and reciprocal hreflang? |
| Manual native writing | Uses a fluent writer or reviewer for market-specific copy | Who owns updates and quality control over time? |
Questions
Before you start
Product facts reviewed 2026-09-01.
What is a multilingual AI website builder?
It is a website-building tool that can understand prompts and create website content across more than one language. Casel also separates the language used for the prompt from the language used on the finished website.
Can I build a website without writing the prompt in English?
Yes. You can describe the business in any of Casel's 11 supported languages and independently choose the language the finished website should use.
Which languages does Casel currently support?
Casel currently supports English, German, Spanish, French, Hindi, Indonesian, Japanese, Korean, Malay, Tamil, and Simplified Chinese.
Does Casel translate an English template?
No. Casel uses the business context, audience, and chosen website language to write the page direction for that audience. It is not a blind word-for-word translation pass.
Can the prompt and website use different languages?
Yes. A founder can explain the business in Spanish, Hindi, German, or another supported language and choose a different supported language for the website readers.
Will each language have its own SEO URL?
This Casel V1 build creates one primary website-language preview. A production multilingual site should give every published language a stable crawlable URL with appropriate canonical and hreflang annotations.
How much does the first website cost?
The Trial pack costs $2.99 once for one complete website and three follow-up changes. No subscription starts automatically; optional plans support ongoing sites and prompts.
Do multilingual AI results need human review?
Yes. A fluent reviewer should check names, claims, market terminology, tone, and customer actions before publication, especially for regulated or high-stakes content.
