Welcome to the AI Math Tutor. Click anywhere on the screen to skip the introduction. You can enter text using the on-screen braille keyboard or by holding the spacebar to speak. For faster typing, you can use six-key braille input: the S, D, and F keys correspond to braille dots 1, 2, and 3, while the J, K, and L keys correspond to dots 4, 5, and 6. Once you've selected your braille dots, click the 'Insert Character' button to send the character to the chatbot.
