Introducing SAM – a revolutionary web application designed to transform the way you learn from lecture videos. With SAM, you can effortlessly upload any lecture video alongside its corresponding slides, creating a personalized study session tailored just for you. SAM isn't just a passive learning tool; it's an interactive mentor that's there with you every step of the way.

SAM's advanced artificial intelligence understands the entirety of the video's context and the corresponding slides, enabling it to provide comprehensive assistance. It seamlessly integrates with the lecture content, offering real-time explanations and insights. Moreover, SAM is proficient in handling formulas, equations, and complex concepts. Whether you need clarification on a mathematical formula or a detailed explanation of a scientific theory, SAM is equipped to assist you effectively.

As you progress through the video, SAM allows you to ask questions in real-time whenever a concept isn't clear. This immediate feedback ensures that you grasp the material thoroughly, enhancing your understanding and retention.

Interactive Learning: As you watch a lecture video, SAM is always ready to assist. Didn’t understand a concept? Just ask! SAM provides instant clarifications, ensuring you grasp every topic thoroughly. This real-time interaction fosters a dynamic learning experience, where students actively shape their own understanding. Research shows that human-AI interaction enhances learning outcomes by promoting curiosity and exploration. With SAM, learners maintain full agency — deciding when to seek help, what questions to ask, and how deeply to dive into a topic, turning passive watching into an active, personalized learning journey.

Flexibility: Learn at your own pace, on your own schedule. SAM is available 24/7, ready to assist you whenever you need. With SAM's comprehensive understanding of the lecture context and slides, you can review material at any time and receive personalized guidance to enhance your understanding and retention.

Latest Results: Younger participants (18–27) showed the greatest knowledge gains with SAM, while learners aged 28–37 performed better in the control group, suggesting SAM may be more effective for digital-native learners. Students with flexible schedules outperformed full-time workers, likely due to spending more time actively engaging with SAM's real-time support. Users with prior knowledge asked more questions, typically 2–3 minutes after a new topic, and questions spiked at the lecture’s end for summaries or clarification. Learners appreciated SAM’s fast responses and interactivity, expressing a high willingness to use it again. Though user feedback may be biased due to unfamiliarity with the topic, expert evaluations confirmed that 97.6% of SAM’s answers were factually correct. Rare hallucinations mostly involved incomplete or misaligned content, highlighting areas for future improvement. Overall, SAM proved to be a reliable tool that enhances learning through instant, context-aware support.
