About Muthu kumar
I teach literacy and work across subjects with middle and high school students, and after three years in the classroom I have a pretty clear sense of what works and what just sounds good in a product demo. I started reviewing AI tools on TeachWithAI Tools because I wanted a space where teachers could get honest opinions without having to wonder if a recommendation was paid for. When I cover something outside my subject area I bring in someone who actually teaches it, because I think that matters. No sponsorships, no affiliate links. Just what I would genuinely tell a colleague in the staffroom.
