You guys should check out I busted my something or other vibe coding it so I feel all the pain you were describing in the space, but it certainly works now. It's the x402 gateway for @KorraFinance. There are QuantFi elements (check her track record). But her greatest value to you would be (social media sentiment x actual market price) divergence signals your agents can just pay-per-call for. Talk to @MatiGreenspan about it on a @QE4Everyone space... they get mad reach.

I built a tool that tells you why a website “looks vibe coded” and how to improve it. Some of us use vibe coding because it’s insanely fast, and honestly, a lot of the results are pretty good. But there’s also this weird thing where you open a website and can almost instantly tell it was vibe coded. Same cards, same rounded corners, same gradients, same spacing, same component-library feel. People usually just call it “AI slop,” but I wanted to understand what actually creates that feeling.

Talk to an AI front desk agent for tutoring centers that refuses to invent prices.

Meridian - AI front desk for tutoring centers that refuses to invent a price Tutoring centers lose students before they ever meet them. A parent emails at 9 PM about algebra help; nobody answers until morning, and the family books somewhere else. I'm in high school. I spent four months building the front desk that does answer: it replies in seconds, handles the actual back-and-forth about price and scheduling, and books the intro session on the center's calendar.

Generate QR codes instantly with Dimas' free, no-login toolbox.
u/Live_Mathematician20 · Reddit
I created a website with free tools. It all started when my colleague reached me with a complaint that she created a few QR codes, and after a week they started showing paywall. By that time those QR codes were printed on promo banners. I remember Internet as a place where you find a tool, use it and leave. That's it - no paywalls, no subscriptions, no accounts. So I decided to put a piece of those beautiful Internet back and created a small toolbox site - dimastoolbox.com Of
