Feedback on app to improve communication

Hi everyone! We are building Poise - an AI based communication coach that listens to you in online meetings and provides real-time, post-meeting feedback and personalized recommendations to help you improve. We've just launched our closed beta and would love to get feedback from this group.
We are hoping to especially help founders communicate their stories better. Please signup on the page (https://www.getpoise.com/), comment here or reach out to me directly.
