TranslateNext

A tiny, beautiful, free, open-source extension for real-time website, PDF, and video subtitle translation.

TranslateNext seamlessly integrates AI translation into your browsing workflow, making it easier than ever to enjoy content in your own language. It features real-time bilingual subtitles for videos, accurate PDF translation with layout preservation, instant text selection translation, and full-page multilingual translation—all within a clean, open-source interface. TranslateNext is a breath of fresh air compared to traditional translators. It uses the latest and greatest LLMs (OpenAI, Gemini, Claude, DeepL, etc.) and VLM to really get to grips with context, delivering translations that feel as natural as can be and are just like the human voice. 🚀 Privacy-First & Open Source: TranslateNext is a project created and maintained by an independent developer.
