Technical details
Description
CatalyzeX is a free browser extension that enhances your research workflow by automatically locating open-source code implementations for research papers across numerous platforms. It integrates seamlessly into your browsing experience, inserting visible [CODE] buttons next to papers on Google, ArXiv, Google Scholar, PubMed, IEEE, GitHub, Twitter/X, and other search engines, forums, LLM/AI chats, and academic websites. When you click a [CODE] button, you are taken directly to the corresponding open-source repository, saving you the time of manually searching for implementations.
Key Features
- Automatic Code Discovery: As you browse normally, the extension scans pages for research papers and automatically adds [CODE] buttons when it detects any linked open-source implementations. This works on a wide range of sites, including major search engines and academic databases, ensuring you never miss a codebase for a paper of interest.
- Alert Creation: A bell icon appears next to papers, allowing you to set up alerts for new code releases on specific topics, papers, or authors. This is particularly useful for staying updated on the latest developments in your field without constantly revisiting the same pages.
- Ask Authors Questions: A question box is placed next to papers, enabling you to directly submit inquiries to the paper authors. This feature facilitates direct communication for clarifications, collaboration, or deeper understanding of the research.
CatalyzeX is powered by the CatalyzeX.com repository, which is used by thousands of engineers, researchers, developers, and tech leaders worldwide to browse algorithms, models, and papers with code for state-of-the-art developments in AI, data science, computer vision, speech recognition, deep learning, and large language models. The extension respects your privacy: it does not track your search history or personal data. It only inserts buttons and question boxes on pages where papers are detected. For feedback or issues, contact [email protected]. CatalyzeX also works on Opera and UC Browser, and Firefox and Edge add-ons are available separately.
