PrepAI is an interview-preparation platform that pairs ~900 hand-authored, browser-runnable coding drills across six language tracks (JavaScript, TypeScript, HTML, CSS, Node.js, Node microservices) with mock interviews, peer reviews, gamification, and a Gemini-powered AI mentor. Each drill is a typed object with a starter, a hidden assertSource test suite, and three tiers of progressive hints, executed instantly in a sandboxed JS Web Worker (CodeMirror 6 by default, Monaco one toggle away) — no server-side code-execution cost. Beyond drills it offers timed mock interviews (AI, peer, or mentor-led), peer code reviews with reputation, gamified leaderboards, and D3 progress dashboards, with five roles (Candidate, Mentor, Instructor, HR Reviewer, Admin) sharing one product. Built on React 19.2 with the React Compiler, Vite 8, TypeScript 6, and Capacitor 8 for Android, monetized by an honest Free / Pro $8 / Ultimate $14 subscription that never locks away the core learning.
