Twinfinder is an AI tool that allows users to upload their photo and discover their celebrity lookalikes from a database of thousands of famous people from around the world and throughout history. The tool uses advanced measurements and calculations to identify the closest match based on facial features, rather than factors such as skin color, ethnicity, weight, or gender. The tool is fast and accurate, allowing users to drag and drop files that are less than 30mb in size in .jpeg or .png format for analysis.
