Amazon Personalize

Amazon Personalize delivers real-time recommendations using the same machine learning technology perfected by Amazon.com.

This managed service automates the complex ML pipeline (data processing, feature engineering, and model training) to serve hyper-specific content to users. Developers feed activity streams—like page views or signups—into the API to generate personalized product rankings and search results. It handles high-scale workloads for brands like Lotte Mart and Subway, improving click-through rates by up to 15 percent through specialized recipes for 'Similar Items' or 'User Segmentation.' By abstracting the infrastructure, Personalize allows teams to deploy sophisticated ranking models in days rather than months.
