Hadar Shemesh built Delphi, an AI companion that teaches English with his teaching style and personality, available 24/7 for shadowing practice and conversation drills. Students use it during commutes and get instant answers to questions. The AI boosted membership retention significantly by giving learners the support they couldn't get from live coaching calls alone.
Delphi is all my knowledge, a little bit of my personality, my values, the way I coach, all of that in one place, accessible for my students 24/7. Are you ready to take your English skills to the next level? Hi everyone, it's Siddharth. Hi everyone, it's Siddharth, and I am here to help you sound confident, clear, and proud when speaking English. Now, even though in my online programs there was the content and there were a lot of coaching calls, I wasn't always available for everyone. We have students from all around the world and the time zone was not ideal for many of them. Delphi was a game changer for me. Hi, I'm Hadar and I'm so happy you're here. Let's get you speaking English with clarity, confidence, and freedom. Can we practice shadowing? Sure. The best way to practice shadowing— And now I just tell them, go do it with Hadar AI. When you get stuck, ask Hadar AI. Go practice with Hadar AI. They use it for shadowing practice where Hadar AI speaks and they repeat the sentences, or they use it to just have conversations, or they really use it to access my knowledge and they ask questions about life and about personal growth. I have one student who told me that I'm a part of her commute to work. Every single day when she goes to work, she calls me and then we have a conversation, and I absolutely love it. They save so much money because they can work with the real me and in between work with Hadar AI. We were really able to increase our retention rate in our membership significantly once we introduced Hadar AI. And to me, that is very telling. It means that they're getting that part that they didn't have before.
