What is Lufe AI?
Lufe AI is a translation tool, delivered mainly as a Chrome browser extension, that displays web pages in two languages so the original and the translation can be read together. It is aimed at language learners and at people who read foreign-language sites, with adapted support for Reddit, YouTube, Discord, WhatsApp and Threads. The extension detects the page language automatically, lets users change how translations are displayed, and offers a choice of engines: conventional machine translation from Google, Bing and Yandex, or AI models from ChatGPT, Claude and Gemini. Selecting a word brings up an instant translation with pronunciation. Separate tools translate the text found in uploaded images and in PDF files. More than 100 languages are supported. Machine translation is free and unlimited, while AI translation draws on credits included in the paid Starter, Standard and Premium plans.
