Astra AI is specifically designed for primary school, high school, and university students who want to improve their grades, pass exams, and truly understand material rather than just memorize it.

The platform is trusted by over 700,000 users across Europe, particularly in Slovenia, Germany, and the United States.
The platform offers a money-back guarantee: if your grade doesn't improve by at least two levels (or 2 points for math), you get your money back.
