LocalizeAI is a single-file tool that translates your website content into 12 languages: Spanish, French, German, Portuguese, Italian, Dutch, Polish, Hindi, Arabic, Chinese Simplified, Japanese, and Korean. Paste your text, pick your languages, and it translates your page title, meta description, and content, and generates the hreflang block for multilingual SEO. Works with the free MyMemory provider with no key required, or bring your own DeepL, Google, or Microsoft key. One file, no subscription, works offline in your browser except for the translation calls themselves. Translation quality varies by language; you pay nothing per translation beyond any key you choose to bring.
