AI Quiz Bot

Contextual evaluation engine running TensorFlow.js entirely inside the browser.

Inference Location100% In-Browser
Evaluation Latency< 15ms Local
Server Cost$0.00 / Zero Leakage

Problem & Challenge

Most AI quiz tools send user inputs to expensive, slow external LLM APIs on every keystroke. This project pushed evaluation entirely to client-side tensors for instant scoring with zero hosting overhead.

Engineering Architecture

In-browser model execution with TensorFlow.js and Web Workers for non-blocking UI threads
Client-side semantic similarity comparison for automated free-text response grading
Zero external server dependencies or API costs per evaluation cycle
