SideLingo — AI Web Translator

Bilingual AI translation for pasted text, web pages, PDFs and YouTube links.

SideLingo turns web pages, selected text, PDFs and YouTube subtitles into clear bilingual translations without breaking your reading flow. Translate four ways: • Page — translate readable content and optionally place translations directly beside the original text. • Selection — translate only the text you highlight. • PDF — extract text locally in Chrome, then translate it in structured batches. • YouTube — translate available captions while preserving timestamps. Built for accurate reading: • Automatic source-language detection. • Natural, formal, literal and simplified translation styles. • Personal terminology glossary. • Layout-aware translation that preserves lists, punctuation, numbers and links. • Bilingual original/translation cards with quick copy and clear actions. • Responsive side-panel interface for compact and wide layouts. Privacy by design: SideLingo runs only after you ask it to translate. It does not read passwords, form values or cookies, and it does not create a browsing-history log. PDF text is extracted locally before the selected text is sent for translation over HTTPS. The free version includes 20 translation actions per day.
