NetEase Youdao launches interactive math tutoring Agent Euler
KEY FACTS
- NetEase Youdao has launched an interactive math tutoring Agent called Euler, now available in app stores.
- The product offers step-by-step explanations: it first hints at the direction of thinking, then unfolds the derivation, and classifies the method at the end.
- Students can ask follow-up questions about specific steps, and the explanation adjusts dynamically based on their actual understanding.
- The product uses dynamic blackboard writing and graphical demonstrations to present abstract relationships such as geometric auxiliary lines and function graphs.
- Youdao was founded in 2006, and its first-generation AI question-answering pen sold out after launching in February 2025.

PHYSIX OBSERVATION
Search-for-answer tools have long been criticized for giving only answers without explaining the reasoning; Euler shifts the competitive focus to the explanation process itself. For the industry, this means the moat for learning hardware is shifting from the size of the question bank to the model's tutoring capability; for users, the standard for judging a product should also shift from how fast it searches to how thoroughly it explains.
