Jev AI Just Made AI Apps 100X Better!

So today, I'm gonna show you a powerful app that I've created with Jev AI. So this is the app, as you can see, it runs in real time. It's basically using Jev AI to create decisions in real time. So for example, I can give myself a microphone over here. I can change the headphones to something like this, and it works almost instantly. This is pretty much real time video, as you can see here. And we can change our outfit. This app works in real time, and it's unbelievably fast, as you can see, using Jev AI. So I'm going to show you how to build real time live apps like you see today. And you can see the Jev cost over here. So it is very cheap to use. Really cool. This is actually based and inspired by Nathaniel Tang. So thank you very much for the idea. Fantastic idea. With that, we're going to get straight into how to do this. So what is Jev AI? Well, most AI models write. You ask something, then type an answer word by word, and that takes seconds. Jev doesn't write at all. You hand it three things, which is a situation. For example, I can say, I'm giving a keynote tomorrow. I'm wearing a t-shirt and shorts, whatever it is, a question. For example, which jacket should I wear? And then also a list of allowed answers. So for example, red blazer, leather jacket, overcoat, or, you know, keep what I have. It picks one answer and then tells you how sure it is. So for example, like a red blazer, 81% sure. It never writes a paragraph or explains itself. Now, because it never writes, the answer is in roughly half a second. And it was 95 to 99.5% cheaper than the models actually tested against it. So you can ask it like hundreds of small questions without even noticing. So you want to think of it like the fast part of your brain. When you see a red light, you don't write an essay about it, you just stop. Jev is built for that kind of snap call. Now, why does Jev suit an app like this?

So basically, there are three reasons.

Number one is speed, right? So a mirror that takes five seconds to react feels like it's not working. But Jev answers faster than you can actually finish noticing you asked. So in my test, the full writing model takes about 4.6 seconds for the same decision. You can only answer from your list. A writing model might say, for example, wear a nice Navy cardigan, and when you don't own one, the app just breaks. Jev can only pick from the closet you gave it, which you can see right here.

So every answer is something like the app can actually use, and it tells you how sure it is. Now, you can also answer many questions in one go.

So one sentence from you becomes like seven questions at once. So for example, what kind of request is it? The top, the jacket, the trousers, the shoes, the extras, and the room itself. All seven come back in under a second. That's how we built it. So how can you emulate this sort of system? How does it work step by step? So first of all, you got part one, which is the ear. And this is the speech feature that's already actually built into Chrome. So it can turn your voice into text, and you can type instead. You don't even need to use AI for that part. Part number two is the brain, which is Jev.

So this is basically like a small program running on your Mac. When texts arrive, it sends Jev to your sentence, what are you currently wearing, and seven questions, each with its allowed answers. And the closet is a simple list. So every item has a name and one line saying when you would wear it. So for example, for a red blazer, that line is Julian's signature on stage look, keynotes, conference talks, and that one line per item is all Jev actually knows about how to pick your clothes, which we can check from over here. After Jev picks, the program asks Jev one more question. How well does this outfit fit what he asked for to 3? If the score is under 2, it tells Jev the look clashes and lets it pick again. And then finally, you've got the tailor, which is the picture itself. So we've got two versions. Number one is photo mode. So this is like an image model that takes one photo of you. You can add your own photo, and it repaints the clothes and the room and everything else. The first time it draws a look, that takes about 10 seconds. After that look is saved, it appears instantly. And then we also have live camera mode, which you can see over here, right? And this is basically using my webcam, as you can see, and it uses a real-time video model as well.
