As answered by people managing Qoder IDE and PrepyAI.
PrepyAI's answer:
Software engineers and technical job seekers, primarily fullstack, frontend, and increasingly AI/ML engineers - preparing for technical interviews at tech companies, from early-career developers to experienced engineers switching roles.
PrepyAI's answer:
Next.js/React on the frontend, Node.js backend, Supabase (Postgres) for the database, with Gemini/AI integration powering the AI Coach.
PrepyAI's answer:
Built solo by a fullstack team lead with ~10 years of experience, after seeing firsthand how broken technical interview prep is - stuck between boring static content and prohibitively expensive mock interviews. PrepyAI was built nights and weekends to close that gap with an AI-first approach to interview coaching.
PrepyAI's answer:
Most interview prep tools are either static flashcards/question banks or expensive human mock interviewers ($100–200/hr). PrepyAI sits in between - affordable, available anytime, and powered by an AI Coach that gives feedback on your thinking process in real time, not just pass/fail on the final answer.
PrepyAI's answer:
PrepyAI combines three things most interview-prep tools keep separate: coding rooms, trivia-style knowledge checks, and a real-time AI Coach that actively talks you through your reasoning instead of just grading your final answer. It's built for the AI era of interviewing - not just leetcode grinding, but structured learning paths and badges that track real progress over time.
