"Unbound X1.6 Pro got me through organic chemistry. The step-by-step reasoning is incredible — it doesn't just give answers, it actually explains the mechanism. I went from a C to an A-."

"The overlay is completely invisible during proctored exams. I've used it on ProctorU, Honorlock, and Respondus — never been flagged once. The response speed is unreal."

Marcus T.

"I was skeptical about the $35/month but it paid for itself in my first exam. The math engine solved multivariable problems my professor said were 'extra credit only.' Worth every penny."
