Olá and Oi both mean hello, but they have different tones and contexts. Olá is slightly more formal and neutral, while Oi is casual and friendly. Think of Olá as the equivalent of hello and Oi as hi. Both are widely used in Brazil, so choosing one depends on who you are speaking to and the situation.
