Show HN: I built a tool to practice startup pitching with AI investors

I’m a solo founder who built Pitchine, a tool designed to help founders practice their pitch out loud with an AI-powered simulation of a boardroom of investors.

I realized reading about pitching wasn’t enough ... you really have to say it out loud and get real-time feedback. Pitchine listens to your pitch, asks challenging follow-up questions, and then scores your performance with actionable feedback.

The AI’s responses are modeled on common investor mindsets and questions I studied from YC videos, Paul Graham essays, and real pitch decks.

I’m using it daily myself to prepare for investor calls, and I thought other founders might find it useful too.

Would love any feedback, especially on:

How realistic the investor interactions feel

Features you’d want to see before demo day

Ways to improve the scoring and feedback

Thanks for checking it out!
