Mirror is a privacy-first AI interview coach built for the MongoDB Hackathon (Problem Statement Two: Memory You Can Govern). Traditional AI speech coaches suffer from "AI amnesia," treating every session in isolation. Mirror tracks speech cadence (WPM), verbal fillers, and eye-contact stability 100% locally in the browser, storing episodic memories in MongoDB Atlas with Vector Search. ## How ElevenLabs is Used After each session evaluation, Mirror calls the ElevenLabs Text-to-Speech API (`eleven_turbo_v2_5` model) to synthesize spoken, empathetic coaching critiques that speak directly to the candidate: > *"Your pace improved from 118 WPM to 142 words per minute. Eye contact remains your biggest growth area. Keep your gaze anchored to the camera lens."*
