R Discovery: Academic Research

Jul 23, 2025

With this update, we're bringing the much-loved Chat PDF from web to mobile. If you've ever struggled to read full-text articles or PDFs on your phone, Chat PDF makes it better by giving you quick summaries, answers, and insights from the content. It works for both PDFs and full texts, and your chats sync seamlessly with the web, so you can continue right where you left off. We've also introduced retracted tags to alert you when a paper has been retracted and may be unreliable for citation.
