As answered by people managing speaking.app and Cert Decoder.
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.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
speaking.app's answer
speaking.app is a modern web application. There is nothing to download or install.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
speaking.app's answer
speaking.app is for people with a high-stakes speaking moment coming up, and the organizations that train them.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
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.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
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.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
