Most interview prep platforms focus on leetcode-style problems. ByteMentor AI is different. It gives you 13+ hands-on practice tools that cover the stuff engineers actually do at work: debugging broken code, writing SQL queries, doing system design, code reviews, behavioral interviews, and more. An AI tutor guides you through each session with personalized feedback. Built by a solo dev as a side project. Free to use with generous daily limits on every tool.

Hey everyone! Thanks for checking out ByteMentor AI. I built this because I kept seeing friends and colleagues get laid off, and most of them told me the same thing: "I know how to code, but I don't know where to practice the real stuff." Things like debugging someone else's code, reviewing a PR, or talking through a system design. Leetcode is great for algorithms but it doesn't cover half of what you actually do on the job. So I started building this on nights and weekends. Right now there are 13+ practice modes and I'm actively adding more. The AI gives you personalized problems and real-time feedback, almost like pair programming with a patient mentor. It's free to use. I'm paying for the AI costs out of pocket, so there are some daily rate limits, but they're pretty generous. I would really love your feedback. There's a form on the site, or just drop a comment here. What tools would be most useful to you? What's missing? I'm a one-person team so every suggestion genuinely shapes what I build next. Thanks for the support!
