WeBWorK Parentheses Autocomplete is a free Chrome extension developed by caseyw. This add-on falls under the Browsers category and specifically the Add-ons & Tools subcategory.

The main feature of this extension is its ability to automatically complete parentheses when typing in WeBWorK. With this extension, whenever you type an opening parenthesis, it will automatically close it for you. This saves time and eliminates the need to manually type the closing parenthesis.

In addition to the parentheses autocomplete feature, this extension also includes an experimental and buggy integration with Wolfram|Alpha. By clicking on an equation, the extension will attempt to display it using Wolfram|Alpha. However, it is important to note that the Wolfram|Alpha integration may not always provide accurate results, so it is advised not to rely too heavily on it.

Overall, WeBWorK Parentheses Autocomplete is a useful tool for users of WeBWorK who frequently work with parentheses. It streamlines the typing process and offers additional functionality with its Wolfram|Alpha integration, although with some limitations.
