WhoKnowsMe is a web-based application that allows users to create a short, personalized quiz about themselves and share it with others via a single link. The primary function of the tool is to test how well friends, family, or group chat members know the quiz creator. The quiz typically consists of 8 to 10 questions covering topics such as personal preferences, habits, and memorable stories. Participants do not need to install any app or create an account to take the quiz; they simply click the link, answer the questions, and receive a score. After completing the quiz, each participant is given a shareable image that displays their score. This image can be posted on social media platforms like Instagram, Facebook, WhatsApp, or X, which in turn can prompt others to create their own quizzes. The workflow is designed to be quick and straightforward. A user creates a quiz about themselves, sends the generated link to a group chat or social circle, and then watches as scores are submitted. The entire process, from quiz creation to seeing results, is described as taking about two minutes. There is no sign-up requirement for either the quiz maker or the participants. The shareable card that each taker receives functions as a growth mechanism: when someone sees the card posted online, they may become curious and make their own quiz, perpetuating the loop. Typical use cases include group chats among friends, social media challenges, or casual icebreaker activities. The tool is entirely web-based and does not require any downloads or installations. Its technical requirements are minimal, as it operates through a standard browser. The website also includes a frequently asked questions section to address common queries about the service.
