Study with your hands,
not your phone.

Broof is a small box that quizzes you. Gemini writes the questions, you answer with a real joystick, and lights, a screen and a voice tell you how you did.

How it works

Pick a topic or paste your notesChoose a topic with the joystick on the box, or type your own or paste lecture notes on the web page. Gemini writes 8 questions in one call.
Answer with the joystickPush up, right, down or left for A, B, C or D. The box does not care about your notifications.
Get feedback you can see and hearThe LCD and LED go green or red, and a short "why" explains the answer in a normal, coach, or mom voice.
Miss one? It comes backQuestions you get wrong return a few answers later, and each lesson ends with a score and a review of what you missed.

Why it is different

📵

No phone

The phone is the distraction. This box does one thing: it makes you recall.

📝

Your own notes

Quizzes come from what your class actually taught, not generic trivia.

🧠

Learns from mistakes

Every answer comes with a why, and missed questions are asked again.

🎙️

It talks back

Voices by ElevenLabs read questions and explanations aloud.
