EasyRead: Read English PDF papers in comfortable Chinese, locally
Key Highlights
EasyRead is a locally running PDF paper reader whose pitch is simple: "read English papers in comfortable Chinese." It translates page by page in the background, keeps formulas and tables in their original layout, lets you compare against the source at any time, highlight and take notes while reading, and conveniently ask an AI or manage references. For non-native-English researchers, the daily cost of reading literature is real, and EasyRead is built to lower it without sending your PDFs to a stranger's server, which matters even more for unpublished drafts and confidential reviews.
What It Does
The flow is straightforward. You import an English PDF, and EasyRead translates it page by page behind the scenes, preserving the layout of formulas and tables so nothing gets blurry or misaligned. While reading, the original and the translation sit side by side, so you can check any uncertain passage instantly instead of guessing. You can highlight, annotate, and leave notes, and when a question pops up, you ask the AI right in context without switching apps. The result feels less like "running a translator" and more like "reading a bilingual edition" that you control, where the Chinese carries the meaning and the English is always one click away for verification.
Technical Details
It is packaged with Electron and uses Python at its core, which makes a desktop app that feels native on the usual operating systems and keeps your files on your own machine. It can call large models such as Claude Code and Codex for translation and Q&A, and arxiv imports work smoothly, so a paper you find online drops straight into your reading list. Because it is local-first, your papers are not uploaded to a public server, which is better for privacy and for unpublished drafts. Translation quality depends on the connected model, and faithful reconstruction of formulas and layout relies on layout parsing; complex two-column pages may occasionally need a small manual tweak, but the original is always present for checking, so you are never stuck with a wrong translation.
Versus Alternatives
Against online translators and generic PDF translators, EasyRead's selling point is the closed loop of "compare plus annotate plus ask AI plus manage references," not just a block of translated text. The idea is close to Zotero's translation plugins, but EasyRead folds reading, Q&A, and reference management into one desktop app, which is more convenient and less disruptive for non-native-English graduate students and researchers. You do not lose your place hopping between a translator tab, a PDF viewer, and a notes app; the whole reading session lives in one window, and the notes you take stay attached to the paper they came from.
Industry Impact and Use Cases
The value is most direct for non-native-English research readers: the barrier to reading literature drops noticeably, and the time saved compounds across a semester of weekly reading. Simply put, it turns "wrestling with an English PDF" into "Chinese-first, source-checkable, ask-anytime," which fits daily literature surveys, lab-meeting prep, and note-taking during the writing phase. It also makes it easy to turn what you read into reusable notes and a managed reference library, so the next paper builds on the last one instead of starting from scratch, and the effort you spent understanding a paper pays back later.
Practical Notes
To start, grab the desktop build from the project's homepage and open a paper you already need to read; the translation runs locally, so give the first batch a moment to warm up. Connect the model you trust for translation quality, and keep the original pane open while you read so you can verify terminology. Use highlights and notes as you go rather than after, since they are easier to review later. For a research workflow, export or sync your notes into your reference manager so the reading and the writing stay connected. Check the license before any commercial or classroom use, and avoid pointing it at documents you are not allowed to process locally. If a paper matters, read the methods section in the original English even after translation, because that is where subtle claims tend to hide. A good habit is to export the notes you take into your reference manager at the end of each session, so the reading you did today directly feeds the writing you will do next week.
