Vibe-coding a kid-friendly AI fortune teller for your Halloween festivities | Marco Casalaina

Welcome to a spooky and unplanned Halloween edition of How I AI. I'm Clarvo, product leader and AI obsessive here on a mission to help you use LLMs to do spooky stuff for your kids. Today we had a haunted episode recording that we couldn't get to work. So instead of our regular scheduled programming, we did a quick Halloween vibe code that I think some of you parents out there will be inspired by. If you have other Halloween vibe codes, please share them with us in the comments and enjoy this very short episode of How I AI Halloween Edition. Marco, we may we may not be able to do our podcast today. We are haunted >> by >> expired expired corporate credit cards, but you have a a Halloweenbased AI use case we're going to talk about instead just for a few minutes before we >> res. I do. And maybe I'll I'll kind of do it live on the fly here. >> Yes. >> And so why don't we why don't we not just talk about it, why don't we actually do it. So I'm dressed as Captain Peicard right now. Uh as I do every year dressed as Captain Peicard. I mean, it naturally fits with my, you know, >> and stuff like that. Of course, I am a huge Star Trek fan. I'm in the middle of Strange New Worlds right now, season 4, >> but uh by night, at least for Halloween, I do something a little bit different. I am the block fortune teller. So, this is the Halloween party block that I live on here in Pedmont, California. And so, we will block off the street and all of our neighbors do crazy stuff. And so, you know, my neighbor across the street is going to have all this projection stuff going on and they have like fire coming out of something and but what I do well I am a fortune teller. So, traditionally uh what I have done for the past few years is that I have pre-created fortunes. So, I set up this table and on this table uh I have a a crystal ball and the crystal ball glows and stuff like that. It's not a high-tech crystal ball. has nothing but a couple of LED lights in it. But the kids come up and there's lots of kids in town, you know, hundreds of them really come up and they they will get their fortunes from this thing. Now, in reality, what I did was I in the past had precreated these fortunes. So, I make a list of them with GPT3 and then GPT4 and I store them in a note on my phone and I kind of keep it between my legs under the table and I'll kind of pick one at random. So, when a kid comes up, I'll pick this one and I make kind of kid-friendly fortunes. Now, this year, I was thinking about doing this, and since we're talking, I'm gonna do this live now. I'm gonna actually do this live. I'm gonna let me give you >> We're gonna Are you gonna read my fortune? >> Uh, we're gonna we're going to make a fortune for you. Yeah. >> Yes. >> So, I think that for this now, there's lots of tools that I can use to do this. I can use Lovable. I can use Bolt. I can use Vzero. I'm going to use GitHub Spark for this one. >> Was not expecting a GitHub Spark today on Halloween, so this is exciting for me. >> How about that? Okay. So I'm going to say make a mobile app which when I click a button generates a new fortune in the context of a fortune teller. Okay. Uh I don't think I need to tell it much more than that. It's probably going to kind of work on the first try. Well, we'll see. Let's see what this does. Now you know in other circumstances I have sometimes given it like a list of things to scroll between. You might have seen on the screen that earlier I had a chemistry ion flashcards app. My daughter uh is in honors chemistry and she was at the time studying polyatomic ions uh chlorate perchlorate you know sulfate stuff like that. And uh she needed to memorize the name to the the formula of these poly ions. And so I made a flashc cards app with this thing which actually worked really well. I mean I just gave it basically the list of the polyatomic ions and it totally freaking did it in this kind of flash card interface that worked on the phone and so that was pretty nice. That's kind of one of the reasons why I decided to go with GitHub Spark for this one is because I know that kind of worked for me before and in a way you could look at this as kind of being a flashc card app too. It's going to kind of make these flash cards of fortunes I guess. >> Um >> oh my gosh. Well, I I have a block party tomorrow, so I might steal your idea. >> You could do this. >> Definitely pass for a fortune teller as well, you know. >> Yeah. Oh my gosh. Okay, so this is going to Oh, it made a PRD. That's, you know, I loved. Let's see. Can we see it? Let's see if we can see what it's doing while it's doing it. Oh, it does. Okay. So, wow. It's really It's going fast and furious over here. So, it's it's totally writing this PRD over here. And now it's it's made a page index. So it's starting to make the actual HTML. So it's it's going to write this in HTML and you know this is this is common and now it's got some CSS. So it's going to style uh the page. Uh but I mean this is this is vibe coding or anyway front-end vibe coding as we do it today. Uh now in reality though I mean when I'm doing real vibe coding uh projects and while this thing is working since I actually already have this on my screen I'm going to bust this out over here. Now, if I'm doing a real project, like a serious project, not just a little fortune teller app nowadays, I will 100% use specit. Uh I absolutely do use spec kit. In fact, it so happens I was earlier today working on just such a project. So, I am by the way, I'm VB products of corei at Microsoft. However, uh I do come from an engineering background and I still code pretty much every day something. So, I'm working on this project and in this project uh where I did use spec kit. So here like this is a full feature specification that I'm working on. I have this whole agent thing that I'm I'm working on and uh I am adding this ability to give user feedback. So this agent will like fill out a questionnaire for me and that's cool but I want to be able to pick a a cell a question and be like no no no you did that wrong fix it. And then the agent should just wake up and do it when you use spec kit. And so like this is the proper way to write a spec. Uh when you use spec kit it does this stuff over here. So you see what it's going to do. it throws these questions at me. So, it's like, wait a minute, how long should the feedback be? What if the user gives you like a ton of feedback? Then what do I do? And it it'll it'll lob all of these questions at me while it does this. So, spec kit is cool. It's totally free. It works with like in this case I'm using it with GitHub profil, but it works with FOD code and it works with cursor and all these other things. So, that is super cool. Uh, I love it. It helps you write a better spec. Uh, but >> oh, look at this. >> My app is here. Okay. Tap to reveal your fortune, the cosmos. >> Okay, >> I'm very excited about this. >> Wow. Okay, >> that's a little bit too uh >> let me let me read this for people that are not on video. In the tapestry of the cosmos, the stars weave a path illuminated by your dreams. Trust in their guiding light. Now, what I like about this is it is completely ambiguous and means nothing. Excellent. excellent fortune, but I bet you want it to be a little more fun and kids friendly for for your use case. >> And so over here on the left hand side, you can see that I'm saying make each fortune only one sentence and make it kid-friendly. So now I'm going to kind of prompt my way towards doing something and it's starting to generate again. So I mean I mean you got to admit though, I mean it's pretty freaking good on the first try. >> Really good. You know what? I haven't seen um this GitHub Spark uh done live, but the design is actually really cute. So, so often in these vibe coding tools, you get these incredibly boring designs, but that is actually quite quite lovely. Okay. >> All right. Did we get it? >> It's done. It says it's done. So, here we go. Let's see what happens. >> Mystic Oracle, what is my fortune? When you sprinkle kindness like fairy dust, the whole world transforms into a playground of magical adventures and shimmering smiles. >> That's it. Is that is lovely and kid-friendly. >> Still maybe a little bit on the big words there. I mean, I can >> And on the abstract side, >> yeah, on the abstract side, I mean, uh, let's see. Make the fortunes a little more concrete >> and and let's make them a little more fun >> and maybe a little more humorous. >> Yeah. try not to use such big words. I mean, a lot of times like the kids that'll come up to my fortuneelling booth, they'll be like, you know, two or three years old, you know? >> Yeah. Yeah. >> And for them sometimes I'll like not even use my little app thing and I'll be like, >> "You're going to try a new food today and it's going to be yummy." And their parents will be like, "Thank you." Like >> your candy in your Halloween bag will multiply. But I mean, you know, Peepon is a small town and I actually know a lot of these parents and stuff like that. Sometimes they come back at me later and they're like, "You told my kid this fortune." Like I told one kid a fortune once and it was like, "You're going to make a new friend today." Which actually did come from my my the previous version of this uh generation. >> And uh she said he was talking about it for the whole next day. She was like, "The fortune teller said, "I'm going to make a friend today. Like this is going to be cool." >> Well, your kid's 15. Should I uh tell her she's going to get a car in her future? >> >> Now, okay, now now we're going off the rails here. Okay, here we go. You ready? Here's your This is This one's for you, Claire. Okay, ready? >> This week, you will find a shiny rock that looks like a slice of pizza and makes everyone giggle when you >> like that. That would entertain my six-year-old. >> I mean, that is very concrete for sure. And now, you know, your six-year-old Yeah. would totally be looking for, oh, where's that rock that looks like the slice of pizza? I'm gonna find it. >> That's exactly right. Okay. I >> One more. >> One more. Let's see. One more. This week we're Okay, again with the rock and maybe it's going a little over much on the rocks here. You recover a rock that looks like a cupcake. Sprinkles of that. I mean, this is why you you got to like integration test these things. Are these all rocks? Oh no. Today a fluffy squirrel will steal your snack, but then share a secret about the best hiding spots in the park. Okay. >> I'm surprised the squirrel is not sharing the secret about the best rocks in the park. So, I mean, >> you got it. Okay. I um you know, it's it's Halloween. It's almost 11:00 a.m. I've got my block party is tomorrow. So, we're blocking off the street. We're doing a posth Halloween. Everybody bring your candy so you can give it all more away party. And I'm gonna do this. I'm going to hook it up to voice. >> Sweet. give it like a spooky fortune teller voice and uh set it up out front. Well, Marco, despite our haunted podcast episode, we will get you back on to actually talk about Spectrian development, but thank you for doing our first and maybe an annual tradition of our Halloween AI how I AI episode. Thank you for showing this. >> Every year we'll have like different elements to Halloween every year. >> Perfect. Well, we'll get you back on on the pod soon. And I think I'm going to just I'm going to go cut this and and share it. >> Thanks so much for watching.
