The reason this exists.
I got tired of ChatGPT.
But the real issue wasn't ChatGPT itself. It was asking for help and getting nothing useful back.
Puzzling over something your teacher has already explained in front of 30 other students? I felt stupid. Texting your tutor at 11pm about an integration problem? You feel like you're bothering them. Admitting you don't understand something your friends seem to get? It makes you feel bad about yourself.
So you stay stuck. You don't ask. That's when you start thinking: "Maybe I just suck at maths?"
Every time I asked ChatGPT for help, it gave me an answer that looked right but wasn't. The explanation was either written for someone who already knew calculus, or it was totally incorrect. Integration by substitution, integration by parts, trigonometric identities — it got every method wrong, in a different way, every time. It would write out a solution with complete confidence, and it would be wrong in ways you'd only catch if you followed every single line.
So I built something new. FEZA: What are you stuck on? No judgment. It explains things clearly because it's designed for students who don't understand yet. It marks your working, shows you exactly where you went wrong, and does it at 2am if that's when you need help. No shame. No awkwardness. Just answers.
