When Harvard's researchers reported their striking result last year — students learning more than twice as much with an AI tutor as in an active-learning classroom, in less time — most coverage treated it as a story about artificial intelligence. Read the study closely and it is a story about a teacher. Greg Kestin and his colleagues did not point a generic chatbot at a physics course and hope for the best.
Every museum has her. She has volunteered for thirty years, she gives the Thursday tour, and she knows things no label copy will ever tell you — which portrait makes schoolchildren go quiet, what the founder's letters actually say, the one question visitors ask that takes ten minutes to answer properly. She is the interpretive heart of the museum. She is also there four hours a week, and one day she will retire, and most of what she knows will go home with her.
In 2025, researchers at Harvard published a result that should change how we think about AI in education. In a randomized crossover trial with 194 introductory physics students, Greg Kestin and his colleagues compared a custom-built AI tutor against one of the strongest alternatives available: an active-learning classroom led by experienced instructors. The students who learned with the AI tutor learned more than twice as much — and they did it in less time, reporting greater engagement and motivation along the way.
Understanding the difference between stylistic 3D avatars and photorealistic AI video avatars is essential when choosing the right solution for your needs. Both are types of generative avatars, which operate in real time. These avatars can listen to users or receive text input, and they respond with voice or text. This is different from static AI-generated videos, which do not change or respond to user interaction.

Emiliano De Laurentiis introduces Kathleen Tarochione, founder of the Golden Life Community, to discuss their partnership in creating AI-powered "golden legacy living memoirs" to help older women share their life stories.
For Teachers: Personalized Teaching Assistant
Knowledge Avatar bots are customizable, allowing teachers to upload tests, notes, videos, rubrics, and other resources. This creates a powerful, personalized assistant that can:
"The greatness of humanity is not in being human, but in being humane.” — Mahatma Gandhi
When it comes to addressing knowledge gaps, it helps to go back to basics—starting with concepts.
In this episode, Karl Dakin, a business advisor, discusses a Knowledge Avatar he created called CAP to answer questions about entrepreneurship and funding. He believes Knowledge Avatars, trained with specific, intentionally biased information, provide more accurate answers than general AI platforms. Emiliano De Laurentiis, who helped develop CAP, emphasizes the advantage of Knowledge Avatars in controlling and monetizing intellectual property and their real-time, interactive capabilities.
Brainwaves: The Knowledge Avatar Experience is a vibrant podcast that dives into the dynamic world of Knowledge Avatars, unraveling how these virtual personas are revolutionizing how we learn and interact with information.
In each episode Emiliano De Laurentiis, our host, explores cutting-edge developments, shares insightful conversations with experts, and offers practical tips to harness these digital vanguards for personal and professional growth.
