Brilliant launches personal tutor powered by ElevenLabs

Brilliant, an interactive learning platform, has launched an AI tutor named Koji to enhance math and coding skills through real-time problem-solving, utilizing a step-by-step explanation method powered by ElevenLabs' voice technology. After extensive testing of various voice providers, Brilliant chose a voice for Koji that conveys a friendly and genuine presence, crucial for maintaining learner trust and accuracy in educational contexts. Koji functions as a virtual learning assistant that interacts with users by seeing their screen and offering guidance when they encounter difficulties, with users able to select custom voices for a personalized experience. The development of voice-first educational products like Koji highlights the importance of natural and accurate voice quality, as robotic or uncertain tones can erode confidence in the learning material.
