You can study Portuguese for months and still freeze when it's time to talk. Parlita fixes that by making you speak from the first session: real conversations with an AI partner, living stories you act inside, and the words you stumble on woven into spaced repetition so they stick.
What learning Portuguese is actually like
Portuguese sounds very little like it looks, at least early on. The vowels go nasal in places English never goes, and Brazilian and European Portuguese have drifted far enough apart in rhythm that they can feel like relatives rather than the same language. Pick one and stay with it for a good while before you start listening to the other.
If you have any Spanish at all you are already most of the way in on both vocabulary and grammar, which is why people who come to Portuguese second tend to move alarmingly quickly. The cost of that head start is the occasional small trap. A door in Brazil marked puxe would like you to pull it.
