Luminator is a chrome highlighter extension developed by Wool Digital. It is designed to allow users to specify words and phrases to be highlighted in their chosen colors, making it easier to identify sets of grouped words. The main goal of Luminator is to enable users to find the information they need in a more accessible format.

To use Luminator, you can set the words you want to highlight on a page from the options popup, which can be accessed by right-clicking on the extension icon. Once you have configured your wordlists, simply click the Luminator icon on any website where you would like to see the words highlighted. The words will then be highlighted on the page in your chosen colors.

If you want to undo the highlighting, simply refresh the page and the highlighting will be removed.

Luminator is a free extension available on the Chrome platform. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory.
