Hi Product Hunt! I'm Yura, the solo developer behind Glotti! We’ve all been there: staring at the ceiling the night before a huge investor pitch, a high-stakes performance review, or a difficult conversation with a client. Practicing in the mirror doesn’t help, and traditional text LLMs are too polite—they wait their turn and let you ramble. That’s why I built Glotti. I wanted to build a true "flight simulator" for difficult conversations. By integrating the new Gemini Multimodal Live API via WebSockets, I was able to achieve sub-second voice latency. This means the AI doesn't just listen—it actively spars with you. It can realistically interrupt you (barge-in), push back on your arguments, and challenge you in real-time. You pick a persona (Skeptical VC, Angry Customer, etc.), speak naturally through your mic, and practice defending your points under pressure. Afterward, Glotti generates a data-driven report so you can actually measure and train your resilience over time. I’d love your feedback! What kind of conversational “sparring partner” persona would be most useful to you in your day-to-day work? Drop your thoughts below, and thank you for checking it out!
