LinguaFlow - Bilingual Web & PDF Translator by Kloverdevs

LinguaFlow is an advanced, AI-powered bilingual translator that transforms your web browser and PDF viewer into a seamless, immersive reading experience.

Unlike traditional translators that replace the original text and erase the author’s voice, LinguaFlow uses a non-destructive bilingual approach: it dynamically displays high-quality translations directly alongside or beneath the original content. Maintain full context, preserve the original formatting, and read websites in your native language without losing the nuances of the original text.
