AI Dictionary built in hours with Gemini 3 Pro
“Wow… a cool prototype… so what?”
Most PMs and designers hit the same wall: we can’t move beyond the first vibe prototype.
Designers can’t rely on it inside Figma.
Devs can’t reuse the code.
And it takes way too much time to fine-tune or improve anything meaningful.
So I tested something different.
I built a functional AI dictionary in just a few hours with Gemini 3 Pro.
In this video, I walk through the actual functionality I built — and the real insights behind it.
🎯 The shift: we can now discuss real product quality on day one
Model performance
Responsiveness
Behaviour & safety
Error recovery
...
For the first time, product teams can focus on what actually matters on day one, instead of spending weeks arguing over UI spacing or colour usage... 😉
