Hi JoeTranYT
My name is Daniel. I will be more than happy to assist you.
Microsoft Teams has built-in similarity checks on student assignments named Turnitin to reduce the possibility for students from cheating by checking the similarity. This feature streamlines the grading process while reinforcing to students the importance of creating authentic work.
Please refer to this article: https://support.microsoft.com/en-us/office/use-...
However, MS Team won't track activities you do outside of MS Team such as using search engines etc.
