Question: I'm looking for a tool that can automate product recommendations to customers based on their preferences.

First, Boxx.ai is an AI-powered e-commerce personalization and recommendation engine that can boost conversions and revenue. It offers behavior-based recommendations, personalization across all touchpoints, and integrates with Shopify, Magento and other e-commerce platforms. It's up and running in less than five minutes, and it's GDPR compliant so it won't hurt your site's SEO.

Another powerful option is Recombee, an AI-powered real-time recommender service that's available through a RESTful API and SDKs. It works with a broad range of businesses and lets you control the recommendation engine with your own filters and boosters. It's very high scale, handling more than a billion recommendations per day, and comes with real-time analytics and AI-powered A/B testing to help you optimize KPIs.

LimeSpot is another strong contender, with advanced personalization features like real-time audience segmentation, personalized email and SMS, and multivariate A/B testing. It integrates with Shopify and BigCommerce, and promises big revenue and conversion rate improvements. The visual editor is easy to use, and LimeSpot's continuous optimization based on customer behavior means it's a good way to improve eCommerce sites.

If you prefer a no-code approach, Pickzen is an ecommerce product recommendation engine that uses AI to recommend products and offer product finder quizzes. It offers measurable results and actionable insights, so you can easily customize and optimize for better customer engagement and conversion rates. Pickzen has been used by big brands and has delivered impressive results, including higher conversion and order values.
