Automatic transcript. May contain errors.0:00There's a way to tune your Claude code so you get absolute superpowers. Some of my smartest friends are using this tool and it's called Last 30 Days. It just came out and I had the founder, Matt Van Horn, come on the podcast to show how to use it. What Last 30 Days does is it uses trending data on places like X and Reddit as the starting point for your prompts on Claude code. The cool part is you end up getting way more out of Claude code because the prompts are way more dialed and optimized. enjoy the episode let me know if you think this is cool and i'll see you in there
0:43i feel like i'm in i know i'm in for a treat matt van horn is on the podcast and he's gonna demo something very special matt by the end of this episode what are people gonna to learn they will have a new superpower in clod code it's called slash last 30 days and uh it's gonna for any topic you could possibly imagine from best prompting techniques for a particular tool to how should i use clod bot to what are the greatest rap songs right now it's gonna search x twitter and the web for only things that have happened in the last 30 days and give you a great result and help you be expert my smartest friends are using this right now so i had to ask matt to come on and showcase how to use this so thank you matt uh i say we just get right into it all right yolo let's uh let's go oh i can just uh dive in so we are in cloud code and so this is a skill for cloud code and so once you install it you just type in last 30 days so research any topic from the last 30 days so uh can be anything so let's say i want um let's kick one off right here um most popular rap songs so let's kick that one off and so and then i'll show someone's some pre-can ones that i've done so using the last 30 day school let's research the most popular rap songs let me research some pop rap rap songs from the last 30 days and so right here it's reddit reading what redditors are saying x reading the timeline and then it's also running a a web search so so is the is the thinking like is the reason why you created this is there's so much good data on the internet and you want to use that as like the jumping off point is that why the the reason that i built this tool is i feel like everything is moving so quickly in ai and it's nearly impossible to keep up with the conversation on X, on Reddit, on GitHub.
2:51And I wanted a tool that gives you superpowers to be able to just become expert on any topic based on what's happening on Reddit X and the web very, very quickly because the prompts are changing so quickly. What's happened to it? Like, look at, you know, Molt bot. What's happened there? It's changing so quickly. And so being able to just become expert in something, it kind of reminds me of The Matrix when he gets plugged in and it's like, I know Kung Fu, right? So to be able to do that for any topic very, very quickly is why I built this. And honestly, so I could use it for myself. Looks like our rap research.
3:33So I found one Reddit thread, 19 expos, and the most popular rap songs right now. so it kind of dug in and into hip-hop heads some expos billboard data some spotify data hip-hop heads hip-hop all day rap complex and created this uh this reply so someone in the comment section is going to be like well i could have used perplexity or chat gpt to do that why should i use this yeah so you absolutely could but it's uh and again i'm i'm not fully up to date on which which tools have what access but to set up last 30 days so you need cloud code right so you're already paying for cloud code right so you need that account you need a open ai key because open ai has a deal with reddit it gives you that reddit access uh i'm actually looking into reddit api keys if that's an option to make the the product better that's what i was um that's one of the things my weekend projects and then the the third is you can't search x using your x account you have to use an xai key and so last 30 days pulls in all these api keys and pulls it all together if that makes sense so this is one that i did right before we started so i said last 30 days highest performing cold email frameworks for icp output three email variance subject line so it went on x went on twitter found reddit threads x posts web pages and what's interesting how i use this tool is i often don't even read what it says like sure it's interesting to see what it learned but mostly i just want it to write a good email so i said can you write me some cold emails for getting on Greg Eisenberg's podcast.
5:23Sorry, I spelled your name wrong. Good target. Startup ideas later. It's all about unconventional startup ideas, community building, and founders' unique relevance. What's your angle? What's your credibility signal? Any connection points to Greg? Mutual follows. What timely? Talk about AI tools I'm working on. And I once made a smart oven. Smart oven details gold. Unexpected founders who shipped hardware and software. That's your hook. Here are three email variants. Subject. Smart oven AI tools. Not Arthopathic, Greg, I went from building smart oven to building AI tools. That might sound weird until you hear it.
5:54Turns out the hardest part of hardware taught me exactly what's broken and how people interact with AI. I'm building the fix. Katrina, what does smart oven taught me about AI? So anyway, I literally did nothing here. I barely gave it any context. And it had become expert in different cold emailing concepts. The three Ps framework, praise, picture push, ADA, attention. I've never read any of these in my life. intention-based data trigger framework. And then it just did it for me, if that makes sense, without even me having to read the research. Yeah, I think what's really cool about this is these frameworks, I mean, Ada has been around forever, like OG David Ogilvie days, but other than the other ones, it feels like those are timely frameworks.
6:41Like these emails, like I'm reading these emails and I get a lot of cold email and these are actually ones that would break through the noise so that's what's really cool about this and i didn't even give it much effort i literally said i'm a former smart oven entrepreneur you couldn't have given it like less context and it did okay yeah and then another one i just tried last three days how to get x followers our research people are actually saying um and what i learned replies the number one growth strategy multiple x power users all credit becoming a reply guy as the fastest path to growth shows 30 80 thoughtful replies daily engagement 40 months before posting find larger accounts reply first consistently post at least one x a day five days a week uh reddit threads x threads instagram marketing facebook ads and share your vision what's your account and what's the other followers uh i'm m van horn and i made an ai tool for clod code i don't know what's gonna do now that's the exciting part one one other let's spin off another last 30 days window sorry for all the all the windows so all right so last 30 days
8:04is research Claudebot so I can build an enterprise competitor to make money and not give it away for free. Maybe I'm giving too much context, but I should have just said research Claudebot. Actually, I'm going to do that. I mean, what do you recommend when you're, you know, is it shorter prompts, medium prompts, long prompts, like getting the most out of it? I think it's kind of you prime the engine by first doing just research CloudBot top use cases. So what my vision for this thread of what we're going to do is it's going to learn about CloudBot, right? Check X, check Reddit. And then what I'm going to do is actually load one of my favorite tools, compound engineering.
8:54Shout out to Kevin Rose for introducing me to it. And compound engineering is when I'm starting a new project, is where I do my planning. And so what I want to do here is take this research on from last 30 days from CloudBot and use that as the starting point to kick off a enterprise version of CloudBot and to build it. So let's let this run and see how our other stuff is going. All right. I'm in AI tool for cloud code. AI tools are hot right now. Here's a growth playbook for you. Morning, 40 minutes for your first post. Reply to 10 minutes from Anthropic, Alex Albert, Birch Labs, cloud power users, add genuine value, share a tip, ask a smart question, content type, tool demo, build X today, what it does, cloud code tip, five things I learned X, build in public, by the way, I'm not going to do this.
9:48I think this was just, I actually asked chat GPT for suggestions of what I should demo on your show. And it gave me this one, but quickest wins, pin your best demo tweet, show the tool in action, bio formula, I build tool, one line logo, shipping AI tools for cloud code. That's not bad. No, it's not bad. So let's close this one out. All right, we got cloud code, best use of overnight coding agent management, daily briefings in morning. Do you want to dive deeper? Okay, so now I'm going to call in another tool. Let's throw in workflows plan. Take the context above about ClaudeBot and propose an enterprise version that could make a lot of money.
10:36Just do that. Keep it simple. Yeah, I mean, this is interesting, right? You're taking a trend, open source trend, and you're like, okay, how can I build a product that gets me paid? And it's interesting because there's so many trends that are happening right now on X as a data source and Reddit as a data source that if this is actually good, it's going to help give you ideas and eventually a PRD, right? Yep. Anyway, so it's still making our plan. It's researching still, doing an analysis. so we'll see where that adds up but anyway, do you want to try a last 30 day prompt? Yeah, I mean I'm curious you're seeing all these prompts so the people that listen to this show these are founders, solopreneurs people building businesses they're always looking for unfair advantages what sort of prompt would you suggest that type of person someone who wants to build a business you know is it competitive research is it um you know what are some ideas you have good good question um i mean i think it's it's very good for competitive research i think it's very good for looking at at hot topics um you know i think it's you know we could probably do something like uh let's try it for your your web design idea right you kind of describe poke.com which i missed right so um what web page designs are getting the most love right now yeah because that's interesting because if we you know knowing the trend is just so important and And it also helps give, you know, when I'm designing something, it helps give me ideas.
12:38It's so overwhelming sometimes when you have like a blank page and you don't know where to start. Yep. We've all been there. And I kind of, the thing that inspired this tool was I used to, before I would jump into any type of vibe coding session, I would go on chat GPT 5.2 and I would just say in thinking mode and be like, go, uh, this was for design. I would say, go on Reddit and research Nana banana pro best, best, uh, prompting techniques. And I would do that at the beginning and then I wouldn't even read what it would say. And then I would just be like, okay, give me a prompt. And so it's kind of this like hack of learning Kung Fu, learning the prompts that everyone's using without actually needing to read about it, if that makes sense.
13:33You kind of just like, okay, let's just trust the mind crowd, the world that's out there and use those best practices. All right, we've got a plan. I guess let's open the plan in BBEdit. All right. So this is the plan for the audio listeners. So this is the plan for the MaltBot Enterprise Commercial SaaS Platform. So again, this is not a business plan. This is actually a plan to how to build the software architecture. And I could just then tell Compound Engineering to just go build it. So transform MaltBot, formerly called it into an open source AI person, into a multi-tenant enterprise SaaS platform called MaltBot Enterprise or CloudCloud.
14:21This capitalizes on the viral growth. GitHub stars, B2B adoption, enterprise AI assistance, R30, blah, blah, blah. Why enterprise can't use MaltBot today? No multitasking, no RBA security vulnerabilities, no audit logging. Like there was Movevice required by ServiceNow for market validation. Proposed solution of fully managed enterprise grade MaltBot commercial. I really don't like the name Cloud Cloud. Come on. Come on, LLM. cloud architecture slack webhook discord gateway team hooks message reader core technical components and so kind of it used last 30 days as the basis for its expertise to learn about multbot and then it did the rest and now i could just say okay build it so dude that's crazy it also that that was a pretty that was pretty dialed like that was pretty dialed and again like i'm impressed and llms do nothing about clodbot because it didn't exist before it didn't exist still very very recently uh all right phase one only build a multi-tenant foundation postgres full mvp uh i guess let's uh let's build the proof of concept.
15:43So basically it asked if you wanted to do an MVP. It asked if you wanted to do a bigger build. Is that what I saw? Yeah, exactly. And so I just said, okay, let's just do the demo. Type something else. New repo. Also, can you please give it a better name? Greg, you live in this world. What should we call this thing? I actually don't hate Claude Cloud. Well, they got in trouble for using Claude. Exactly. So why not just call him Malt Cloud? But then we're going to get in trouble with Malt. Malt? Okay, so why don't we call it... Should we go lobster?
16:28I was going to say, why don't we call it Red Lobster? But I think that name is already freaking... All right, let's go with Leet Speak. Let's go with Red Lobster. That's cool. this describes a 40 week product row surveys what scope do you want to do i don't know just just do it just do it why are you asking so many questions all right um all right what do we ask here what web designs are getting the most love right now the most love shopify winner edition yes i remember i saw that one that was that was really awesome that was beautiful look the 3 000 likes 320 retweets the yc landing page so what's funny is I saw this, I didn't actually look at it yet, but I saw that it was getting love and hype.
17:13Praise for Scrappy Home of the Beginning, shop, web lending, all were like jewelry, craftworks design. All agents reported back. Reddit didn't find any topic too visual for tech discussions, but found what tool do you want to use to create design? So it's like, okay, now that I've researched these things, what do you want to design in? All right. So it's kind of pushing you to be like, okay, I've now learned this expertise. Now let's do something with it. So this could literally pump out a Figma design. Is that possible? I haven't spent enough time in Figma in the AI era. All my Figma time was pre-AI.
17:55So I don't know what like prompting Figma even means in 2026. But I don't know. I could just say one and see what happens. Now what are you designing? All right. Now it's diving in. A portfolio landing page for productivity app is fine. One of the suggestions. What are you designing? A SaaS landing page, a portfolio site, an e-commerce homepage for skincare brand, agency website hero. I keep coming back to this, but it is impressive how short your prompts are. Here we go. Here's a prompt for Figma. Apparently that's a thing. Wow. 2026 forward trend. Design an interface that feels warm and human, not cold SAS stuff, but layout.
18:46Anti-grid composition. Hero section uses asymmetrical balance. Headline left. Product screenshots floating right at angle. Sections will flow organic with varied spacing. Not rigid. 12-column uniformity. Typography. One oversized display headline paired with small body text. Add a single hand-drawn underline or circle accent on the keyword. Consider variable. font like satoshi or general sans nature distilled warm cream background charcoal text one muted accent avoid harsh pure white or saturated blues glass morphism element feature card i want to see this it's too bad i don't have figma ai set up but um so that's pretty cool let's see if it can do this for like a nano banana prompt like hey you know i wonder if it can do that can you make this a nano banana pro prompt yep but i didn't ask it to become an expert in a nano banana i didn't ask it to become a nano banana prompt expert so who knows what's going to happen yeah back to telegram and let's see what happens we should get three images your malt bot is typing that's a cool feeling like watching your malt bot type someone needs to visualize that with like a lobster on a keyboard
20:15why did you choose telegram over iMessage or discord or something else because my LLM told me to uh because i'm i'm on a four dollar a month shell account uh for my i don't have the mac mac mini setup and so um the um you can't use iMessage or WhatsApp i believe when you're just on a shell i think you need to run some sort of mac software and so telegram seems to be the default where you when you don't have that and for people who don't know what a shell account is can you just expand on that yeah sorry uh by the way this is our clodbot competitor that it's building i don't know what is going on or what it's building it's adding a demo script showing tenant isolation then i would already set up typescript and node.js that's nice wow that's cool here we go oh yeah not bad i bet it'd be nicer in figma yeah that was pretty solid and again And that was by using slash last 30 days.
21:25What are the hottest webpage designs that the world is excited about right now? Like what's trendy? And then, okay, now use that for my SaaS productivity app. I like how it like circled random words, flow effortlessly more. That's awesome. Yeah, like it feels like hand drawn. It's pretty wild. It's wild times. It's the rate at what we're able to build things and how fast things change. is absolutely wild. So Matt, this has been fun. If people want to get started, what advice do you have in terms of getting the most out of this product? Yeah, so one of the things I'll say is I am not a software engineer.
22:12I have not shipped anything of value since high school. I could argue the webpages I was shipping in high school were not of value either, but at least I could write some basic HTML or some basic scripts. And so what's amazing is being not a software engineer and being able to go into cloud code. Like it seems intimidating. You're in the terminal, setting up a cloud bot seems intimidating. And my recommendation for starting out is set up cloud code. it's magical sign up for the$20 account if you'll be on the$100 and the$200 account probably real soon if you're uh if you're successful um and and what I what I do is I um have keep a chat gpt window open to ask questions to and so I'm kind of moving back and forth and posting lots of screenshots be like there's some error I don't know what's going on help me and so chat gpt 5.2 thinking will be like okay great in your in your shell in your terminal this is what's going on this is why it broke and i'm like okay great what do i do help and then it's just like copy this into the terminal i'm like okay and i again don't even have to read it don't have to overthink it and so kind of just like screenshot trial and error back and forth between chat gpt and my terminal and like i couldn't figure out actually how to post screenshots into my terminal so i asked chat gpt and it's like oh you have to use ctrl v instead of command v and that was the biggest unlock for me in the terminal, figuring out that I could post screenshots with control V.
23:53And anyway, so I recommend getting into Cloud Code and try Last 30 Days, obviously, because it gives you superpowers, but use tools like compound engineering, use skills like, there's another one called superpowers, which is getting a lot of love right now. And you just kind of enter these plan modes and you try and you build things. And I had this idea for the last 30 days and I've never looked at the code for the skill that I wrote, quote unquote. And it was just a lot of trial and error and running more and more terminal windows and testing it and testing it and being like, hey, figure out how to get access to this API.
24:33Hey, figure out how I can do this. Hey, how can my users do this? And going from there. I love that, man. Well, I'll include a link to last 30 days in the show notes, in the description. link where you can follow Matt Van Horn on X. And dude, this is really cool and it's crazy that this is just sort of like a project that you started and it's gaining so much traction. And I think people are just obsessed with Claude Code for good reason. But I think people are just trying to get the most out of it. So this came at a very perfect time and I can't wait to see how it evolves. Thanks for doing a little show and tell for us.
25:15Of course, it was fun being here. Thank you so much, Craig. I appreciate it, Matt. Until next time.
