Academic Question [HEP/GR Tools] is a Chrome extension developed by suchideas.com. This free add-on falls under the Browsers category and specifically the Add-ons & Tools subcategory. The purpose of this extension is to provide quick access to arXiv PDFs and a popup INSPIRE search within the Chrome browser.

The extension offers two main features. Firstly, it includes a toolbar button that allows users to easily access a search interface for INSPIRE. Additionally, it provides a convenient way to open arXiv PDFs by using their identifiers. Users can simply select text on any page, including PDFs opened in the browser, and right-click to open any arXiv PDFs referenced by the selected ID.

It is important to note that this extension is unofficial and not endorsed by INSPIRE or arXiv. However, it was designed with theoretical physicists in mind and aims to be a helpful tool for their research needs.
