Lerna AI helps mobile apps boost their campaign and product recommendation conversions, with the world’s first mobile hyper-personalization recommender. In a post-cookies world where third-party data are dying, apps need to better understand their users and make the most of their first-party data potential. Lerna AI mobile SDK enables apps to personalize their content to each user, by training models on content metadata along with user data (demographic & sensor), on-device. This way it predicts the optimal content for each user at a specific time while preserving user privacy.
