About Us
Who we are
SIM is developed and operated by JOEL G DE OLIVEIRA LTDA, a Brazilian company operating under the trade name EXPONENCIAL INVESTIMENTOS (CNPJ 47.699.636/0001-37).
SIM is a product of the company, not a separate legal entity. Our focus is digital education and educational software: specifically, AI-assisted tutoring and study support. SIM is our flagship product: a personal AI tutor that identifies exactly where a learner gets stuck and helps them move forward from that point.
What we do
SIM breaks down what a student wants to learn into small, manageable steps, adapts explanations when the student doesn't understand, and tracks progress along the way.
SIM is currently available on Android through Google Play, and as a Web application accessible from any modern browser on iPhone, iPad, or computer.
