at a networking event, we met pratham pengoria of JEE Simplified and Solve Arena. we ended up at 
tim hortons in hsr layout, talking for hours about education, jee and neet, and the difference between a flashy demo and something a student will actually return to.
the useful part was not a promise or a headline. it was the specificity. where do students get stuck? which kind of explanation actually changes their understanding? what does a school or platform need before it can trust a new tool?
that conversation pushed 
vivacity away from being a vague AI video idea. it made the work more concrete: use visual explanation to help with the exact questions students cannot yet see their way through.
