11. Albert AI Albert is a self-learning software that automates the creation of marketing campaigns for your brand. It analyzes vast amounts of data to run optimized campaigns autonomously, allowing you to feed in your own creative content and target markets, and then use data from its database to determine key characteristics of a serious buyer. Albert identifies potential customers that match those traits, and runs trial campaigns on a small group of customers—with results refined by Albert himself—before launching it on a larger scale.
