SUN is an AI-powered audio learning app that creates personalized audio courses and book summaries on any topic, almost instantly. Users can choose the topic, voice, pace, and ask questions at any time while listening to receive real-time, context-aware answers, turning every lecture into an interactive learning experience.

The app allows users to generate audio content from a single prompt, choosing from multiple narrator voices and setting the duration from quick 5-minute overviews to in-depth, hours-long explorations. SUN features context-aware conversational AI that understands the lecture context, topic, and learning history to provide tailored responses. The platform offers hyper-personalization that adapts content based on user preferences, listening behavior, and real-time inputs.

SUN's technology includes layered validation with structured data checks, cross-source verification, and real-time sanity filters to minimize hallucinations and ensure trustworthy content. The Q&A engine is grounded in the actual course content rather than generic AI responses, providing context-aware answers during listening sessions.

The app provides an unlimited, always up-to-date catalog that adapts to how users learn, allowing them to gain insights from books and topics quickly. Users can learn about almost anything in nonfiction including philosophy, science, history, business, biographies, psychology, and personal growth.

SUN is designed for mobile learning experiences available through iOS and Android apps, targeting users who want personalized, interactive audio learning with the ability to customize content and engage with material through real-time questioning.
