About Lufe AI
What Is Lufe AI
Lufe AI is a browser extension that translates what you read on the web. Its pitch is bilingual reading: instead of replacing the page, it adds a translation under each line, so you keep the original text in view while you understand it. That format is aimed at language learners who want to pick up a second language from real articles, novels and news rather than from a textbook. You'll find it at Lufe.ai.
The tool works in two layers. Basic machine translation comes from established engines like Google, Yandex and Bing, and it runs without a paid plan. The heavier work reads context and tone rather than working word by word, and it goes to AI models from Gemini, OpenAI and Claude. Lufe AI says AI translation is about five times more accurate than plain machine translation. That figure is the company's own comparison, not an independent benchmark.
Two limits are worth knowing before you install it. The AI tier is credit based, so heavy use runs through an allowance rather than staying flat. And it is a Chrome extension first, which means the whole experience lives inside the browser rather than in a standalone desktop app.
Getting Started
- Install the Lufe AI extension from the Chrome Web Store; no credit card is needed for the free tier
- Open any foreign language webpage and let the extension detect the source language
- Pick your side-by-side view: full dual line, blurred until you hover, or a style you set yourself
- Translate an image or PDF by uploading or clicking into it and sliding across the content
- Move to a paid tier when the free AI allowance runs out and you want unlimited image and PDF translation

Key features
Bilingual Web Translation
The core view lays a translation under each line of the original, so the page stays readable in both languages. You choose how much shows: a full dual line, a blurred version that clears when you hover, or a style you define yourself. For language learners, that setup is the point, since you can test your own reading against the translation only when you need it.
Select to Translate
Highlight a word or phrase and the extension returns a translation right there, and a voice option lets you hear how it sounds. This covers the moment you hit an unfamiliar term and don't want to open a separate tab. The company says the lookups are context aware, so the suggestion fits the sentence rather than a dictionary default.
Image Translation
You can translate text inside an image by uploading it or by clicking into it, and the tool detects the language and reads the text on its own. The display is built to be slid across, so you move through the image and watch the translation track the content. It suits screenshots, signs and photos where the text is baked into the picture and can't be selected.
PDF Translation
Upload a PDF and the extension translates the document into your language. On the free plan each image and PDF caps at 1,500 words, and paid tiers lift that cap entirely. It's a simpler path than copying passages out by hand. The output is a translated read, not a rebuilt original layout.
Multiple Translation Engines
Basic website translation runs on Google, Yandex and Bing with no limit, and the AI layer draws on ChatGPT, Claude and Gemini. That split means you can read most pages for free through machine translation and spend AI credits only where context matters. Several engines on hand also let you compare output when one of them mangles a passage.
Custom Display Styles
The extension lets you set how translation appears, from a side-by-side layout to a mode where the translation stays hidden until you ask for it. The blurred mode is a small but useful touch for learners: you attempt the original first, then reveal the translation to check yourself, which is closer to how you'd study with a tutor than a page that hands you the answer.
