CRUX Knowledge measures users' knowledge based on what they have read and shows them in real time how much they've covered and which article they should read next. Users get rewarded for their focus and progress and can make informed reading decisions, allowing them to successfully navigate the information landscape around any topic. Quantifying knowledge gives content platforms and publishers a numbers-based language to trigger and inform user interactions and communications, and optimize user engagement. The company's revenue model is unique and charges content providers and publishers with a fee based on increased engagement and revenue from using the tool.
