Show HN: LeetDuck – AI voice-to-voice mock interviewer for LeetCode.com (opens in new tab)

I made this because I had trouble "thinking aloud" during technical interviews, even when I knew the optimal solution.

I'm using it right now to work on practicing vocalizing my ideation, which is a huge component of technical interviews that leetcode doesn't cover.

It integrates seamlessly into leetcode.com and sits on your screen as a little "rubber duck."

LeetDuck is automatically configured to proactively ask you a random behavioral question at the start, respond to runs and submits, and ask you about the time and space complexity when you successfully complete the problem.

Let me know what you guys think! Is this actually something other people would use too?
