Solution

KSN Education built NABBLE AI as a serverless, multimodal tutoring platform on Google Cloud so students can get personalized help through text, voice, and screen-share interactions at any time. Vertex AI and Gemini power the core tutoring logic, generating adaptive explanations, quizzes, and verified step-by-step answers that respond to student performance in real time. Cloud Run supplies the serverless execution layer, Firestore secures student learning histories, and Cloud Storage supports the wider application data model without forcing the startup to manage infrastructure directly. Speech-to-Text API and Text-to-Speech AI add spoken interaction, while Cloud Build, Cloud Load Balancing, Cloud CDN and Media CDN, Cloud DNS, and BigQuery support delivery, reliability, and analysis at scale. The system also uses human review and proprietary curriculum tuning to keep answers trustworthy in a high-stakes exam-preparation environment.

Data flow

Student questions arrive through text, voice, or screen-share channels, are processed by Gemini on Vertex AI through serverless Cloud Run services, stored and secured in Firestore and Cloud Storage, and are returned as adaptive explanations, quizzes, or spoken responses while analytics and delivery services monitor platform performance.

Solution architecture

12 components · 5 layers
