PrepDragon

PrepDragon is an AI-powered interview practice tool that provides adaptive feedback for both technical and behavioral rounds. I originally built it to help myself after finding I struggled with confidence during HireVue and other interview settings. I often felt nervous when talking about myself and answering questions.

The main point of an interview is not to rehearse every possible answer; that part can be practiced. Confidence, however, is much harder to develop.

PrepDragon aims to bridge this gap by measuring a user's confidence through eye tracking and tone analysis, then delivering personalized feedback to help improve overall interview performance.

Currently built on Gemini 2.5 Flash, PrepDragon supports drop-in API switching and can be run locally, provided you supply your own API key.
