**scoreBoost** was designed to address a critical issue faced by international healthcare professionals, mainly nurses, who struggle with the speaking or writing components of English proficiency exams like OET and IELTS. These challenges often result in repeated, lengthy, and costly exam retake cycles. Instead of creating a simple text-based chatbot, the developer created an advanced voice roleplay engine by integrating technologies like Voiceflow, Cartesia AI for text-to-speech, Deepgram for speech-to-text, and GPT-4 for scoring. This system simulates real-time interactive examiner roleplays with quick response times and is fully integrated without backend server requirements. The creator of scoreBoost, whose expertise lies in product development from concept to completion, plans to transition to an MBA program and a new AI project focused on sustainability. Consequently, scoreBoost is for sale as a pre-revenue, turnkey intellectual property asset. This ready-to-deploy voice engine boasts high gross profit margins and can be marketed immediately to those retaking the OET exam or adapted for other exams like TOEFL and USMLE, as well as corporate language training programs. The basic software package is available for $9,999. For $20,000, buyers receive full ownership transfer, including personalized onboarding, future expansion specifications, and strategic intellectual property growth. The seller is open to considering custom offers above $10,000.
