# Mipha user guide > Mipha helps people learn English from videos with interactive subtitles, word lookup, explanations and practice based on their learning history. The guide covers product operation, access requirements and common problems. Use the language the reader prefers; do not assume the interface language from their English learning level. Supported languages: es (Español), pt (Português), ja (日本語), fr (Français), ko (한국어), it (Italiano), tr (Türkçe), id (Bahasa Indonesia), zh-Hans (简体中文), zh-Hant (繁體中文), th (ภาษาไทย), vi (Tiếng Việt). There is no English guide. The default is Japanese (ja). ## Reading a guide HTML: https://mipha.ai/{lang}/docs/{slug} Markdown: https://mipha.ai/{lang}/docs/{slug}.md Overview: https://mipha.ai/{lang}/docs/index.md Replace {lang} with a supported language code.
