Holding a room is about attention, not memorization. Two tools make it easy: a teleprompter for your points, and answers on demand for the questions you can't predict.
Big, adjustable talking points in a floating overlay let you keep your gaze up and your delivery steady — no shuffling notes, no dead air.
When someone asks for the number, the example, or the rebuttal you didn't prep, screenshot the slide and pull the answer mid-flow — privately, without breaking eye contact.
The overlay is excluded from screen sharing, so it helps you without ever appearing to your audience. When you must share the whole screen, the phone companion reads the answer in your ear.
