[Product Hunt]( [Read in browser]( [This newsletter is brought to you by]( GOOD MEWS That subject line wasn’t a mistake, but points to you if you remember [that HBO intern](. We’re talking about smarter A/B testing in today’s Product Highlight. But first, some good news. - [Google Maps is getting AI-driven updates.]( Your move, [TikTok](. - [UO is selling “vintage” iPods.]( 🤷‍♀️Needs the “When We Were Young” playlist. - [Boston Dynamics turned Spot into a guide with ChatGPT.]( Alfred in the next Batman? PRODUCT HIGHLIGHT [A UI that changes for its user]( Ah, the old A/B test. It’s been a staple in the back pockets of product people, marketers, and designers for years. But if AI has its way, the A/B test will soon look as old as a 2013 CD-Rom with Photoshop. Reinforcement Learning (RL) has entered the chat, and makers can now use it to do real-time personalization. RL is an area of machine learning concerned with decision-making — learning the optimal behavior to obtain the maximum reward, per Synopsys. Applied to tech apps, it can look like each user seeing a UI that is most likely to get them to press “add to cart," in real-time. That's the idea behind [flowRL](. It's a new product that makers can integrate into their products to leverage Reinforcement Learning. “We use Reinforcement Learning to predict the best UI Variants (of the ones you set up in code) for each user… our model automatically adapts the interface to drive metrics of your choice!” explains maker [Alexey Primechaev](. But is it just a bunch of A/B tests happening really fast? Not exactly. “Traditional A/B testing tools… typically estimate which version performs better on *average* for all users. In contrast, flowRL uses Reinforcement Learning to go beyond averages and tailor experiences for each individual,” writes flowRL CEO [Fred Kurdov](. Getting into the depths of RL sounds like a better job for our [AI newsletter](, but the [highlight]( here is that [flowRL]( says it can give products a 2–3× target metric uplift. [Better than an A/B tests]( Sponsored By Being a founder is HARD. Finding product-market-fit is one of the toughest challenges that constantly poses questions like "Are people using my product? How are they using it? Are they returning to get value week over week?" When first starting out, Segment co-founders didn't understand how important these questions were or how to use analytics to answer them. So they spent 1.5 years and 7 different MVPs in their pursuit of product-market-fit before finding the secret sauce. Segment helps you collect, clean, and act on your customer data. You can now build fast with a reliable, performant, and compliant stack.
