DeepL Translator Browser Extension - Chrome Extension

DeepL Translator Browser Extension is a Chrome extension designed for readers of academic papers who want fast, high-quality translations without leaving the page. When you open a paper page on supported research platforms—arXiv, OpenReview, or the ACL Anthology—the extension automatically detects the abstract and translates it with DeepL as the page loads. The translated version is then inserted directly into the webpage near the original abstract, so you can read both in context without copying text into external tools.

To make comparison easy, the extension includes sentence-level linking between the source and the translated text. When you hover over a sentence in the translation, the corresponding sentence in the original abstract is highlighted (and vice versa, depending on the site layout). This helps you verify meaning, check terminology, and quickly resolve ambiguities—especially useful for technical writing where small wording differences matter.

The extension is also configurable. Beyond the built-in support for common paper repositories, users can add additional translation targets by specifying rules for other sites. This makes it practical for researchers who frequently browse multiple conference pages, lab websites, or institutional repositories.

Once installed, everyday use is simple: navigate to a supported paper page and the translated abstract appears automatically. No workflow changes, no manual copy/paste, and no separate translation window—just an integrated bilingual reading experience optimized for scanning and understanding research abstracts quickly.
