As answered by people managing JavaScript Operator Lookup and speaking.app.
speaking.app's answer:
speaking.app began with a personal realization. Its founder, Bjarte Sunde, an engineer by training, found that in a world increasingly shaped by AI, the skill that mattered most was still an old one: speaking clearly and confidently when it counts. While working on his own communication, he wanted honest feedback and a private way to practice, without an expensive coach and without waiting until the moment had already passed.
The product is built on a simple belief: how you come across in an interview, a pitch, or on stage should not come down to luck or budget. Everyone deserves a place to rehearse, hear how they actually sound, and improve before it matters. What began as a personal tool is now used by individuals, founders, students, and organizations to turn high-stakes speaking from something you hope goes well into something you have prepared for. Built in Dublin by Prosody Ltd, speaking.app is working toward a future where confident communication is something anyone can develop, not a privilege of the few.
speaking.app's answer:
speaking.app analyzes both how you speak and what you say, then coaches you until it becomes second nature.
Most tools stop at delivery metrics. speaking.app tells you what to fix, shows you how, and helps you rehearse it until it sticks.
speaking.app's answer:
Choose speaking.app because it does more than measure your delivery. It helps you fix it and rehearse until you are ready.
It is practice software for getting genuinely better beforehand, not a live in-call copilot.
speaking.app's answer:
speaking.app is for people with a high-stakes speaking moment coming up, and the organizations that train them.
speaking.app's answer:
speaking.app is a modern web application. There is nothing to download or install.
