LessonSide — Your AI tutor for YouTube lessons Make every YouTube lesson count. Ask about anything on screen, get auto study notes, and quiz yourself — all while you watch. 🎯 What it does

Is LessonSide — YouTube Summary · AI Q&A · Quiz Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
