From Idea to Reality in 30 Minutes: How AI Turned My Vision Into a Working App

Your idea is a prompt away from being brought to life.

The power of the current generation of AI models is so great that with just an idea and the ability to articulate it and answer questions, it’s just a prompt away from reality.

This morning as I got ready to present to SMPS Ontario, I realized at 7:30 AM that there is no simple way to show translated captions natively on MacOS.

Yes, MacOS can show live captions, but in the system language, not translated. PowerPoint can do the translation, but only in PowerPoint.

Are there apps that do this? Sure. But those are more subscriptions I don’t need or want.

So I opened up Gemini 2.5 and dictated aloud as I was getting ready what I wanted – to use a local speech recognition software model (NVIDIA Parakeet TDT v2) to automatically transcribe what I was saying in real-time, and then feed it to a local LLM (Google Gemma 3) to translate it into Canadian French.

Gemini 2.5 helped me build the requirements document in 10 minutes. It built the file-by-file workplan in 5 minutes. Then I fired up Cline and had it build the workplan in Python, using Kivy for a simple interface while I took a shower.

When I came back, the app was ready to test. After 10 minutes of debugging, it was live – realtime translation on my computer, using no Internet, no cost, just local models and local code.

My idea was ready before I was even fully dressed for the day.

One of the things I say in my keynotes is that whoever has the most, best ideas (and can articulate them) in the age of AI will win. This is an example of exactly that. I had the idea, and AI brought it to life.

Could it be more polished? Sure. I could add a whole bunch of stuff to it. But the cycle from idea to MVP was under 30 minutes.

What ideas are you sitting on that AI could unleash? Have you asked?
