Signed before the tool is finished. Signed before the new company is even incorporated. I'm building a Marketing Stack for my SaaS company and before I was finished with Phase 1 of the seven planned phases I was thinking about several people who had talked to me recently about their pain in the same area. Made the call, explained the idea, addressed their pain, and signed the deal. If you approach what your are building as a system that can be deeply customized for each user, then you have a product that people will want. Build it to solve your problem but remember that the customization, the personalization, the flexibility, and the agility of what we can build with AI as the newest abstraction layer of software development is what makes what we are doing here better than what SaaS can do. SaaS is a cookie cutter template that the r has to cram themselves into. What we can build is deeply personalized software solutions.

So this is my first try at being a GIT user. The idea is that this is the start of an idea, not a finished product. It's been sitting on my desktop for a bit, and I just need to throw it out into the universe. It's inspired by Information Architecture by Richard Saul Wurman (LATCH) and the desire to be able to 'tune' data to find harmonic correlations. So behold... Signal Harmonics is a cross-domain correlation instrument. You pick signals — GDP, inflation, S&P 500, violent crime, temperature anomaly, social mood, whatever combination — and it shows you how they move together across 2019–2024. Hit "Read the Signals" and Claude gives you an AI interpretation plus a historical parallel from another era that matches the same pattern. The idea: most tools show you one domain at a time. This one asks what happens when you put economy, markets, society, environment, and crime in the same room and listen for the harmony. It's live here: ajpaschka.github.io/signal-harmonics The code is fully open source on GitHub under MIT. I built it intentionally minimal so it's easy to branch. Good starting points if you want to dig in: swap in live API data, add new signal categories, build a different visualization layer, or just run your own version on your own domain. The README walks through the full deploy in about four steps. GitHub: github.com/ajpaschka/signal-harmonics Fork it, build on it, break it. If you make something interesting with it, I'd love to see it. Break it down. Make it better.

I've been running cold email campaigns for clients for 3 years and the biggest shift I've seen isn't the tools. It's what actually gets a reply. Personalization used to mean scraping a name and company from LinkedIn, dropping it in the first line, and hitting send. "Hey {FirstName}, I noticed {Company} and thought..." That worked in 2022. It's dead now. Everyone's doing it and prospects can spot a mail merge from the subject line. What changed for me was treating personalization like actual research instead of a data field. Here's what I started doing: → I scrape the prospect's entire website. Not just the homepage. Blog posts, service pages, case studies, about page, even their contact form if it's there. → Then I feed all of that into OpenAI and have it analyze what they actually do, who they serve, and what problems they're likely dealing with. The AI doesn't just summarize. It finds the specific details nobody mentions in generic outreach. So instead of "I saw you work in logistics," the email opens with "Noticed you handle cross border freight into Mexico. Your blog mentioned customs delays eating 15% of delivery windows." That's the kind of line that gets opened because it doesn't sound like 500 other emails they got that week. The reply rates went from 2-3% with generic personalization to 8-10% with actual research. One prospect replied last week: "Your email won because you actually read our site. Everyone else sent the same template." The system I built does this automatically. Scrapes the website. Analyzes every page. Generates icebreakers that reference non-obvious details. It writes openers like a human who spent 20 minutes studying their business, except it does it for 1,000 prospects in an hour. Here's what I learned building this: Small prompt details make a massive difference. Having OpenAI shorten company names naturally (say "Stripe" not "Stripe Inc.") and reference specific pages beyond the homepage makes it feel real. The difference between "I saw your website" and "I saw your freight tracking dashboard lets customers get ETAs without calling" is everything.

Completed a HABIT Tracking app. “Set your daily HABITS you want to improve on and let the 8th wonder of the world, COMPOUND INTEREST , prosper you in achieving goals and creating new BETTER habits. OPTION MENU Displays your analytics from results of a week, month, quarter, etc. Steps: 1. told Claude chat what I wanted. I said it needs to be a free setup, no subscriptions or fees to start and it recommended I use GitHub, vercel and Supabase. This is to store the data it records when users check off tasks for their daily habits and tracks results. I wanted Oauth so people can login with email. Daily quotes revolving in the ui to keep up motivation. 2.told Claude chat to make me a plan to effectively build this organized and as a pro engineer. 3. Converted the chat into a short Claude Md file and a context file. 4.told it to give me a pro CS Eng folder structure and save it to my docs. 5. Pushed it to git hub and I told it to build. All from VScode we went to work…. And had more than 50% worth of tokens left, as I even used it for other ideas while it was building out task app. This was amazing. Thank you @Jake Van Clief !!! Looking forward to more content of yours. Now time to work on the UI.

I'm curious what everyone here likes to do for fun (of course building stuff with Claude is fun too lol), and if you've applied any AI to your hobby. For me it's been super useful for DND planning and I find I get to stay in creative flow more. Curious what other people are doing
