Goodbye Win 95 theme, hello Liquid Glass(ish)! One-shotted a complete UI transformation of my first @caffeineai demo app. Recorded the prompt, had a shower, came back and it was done! Key takeaways: 💡 Working with AI means the cost of changing your mind approaches zero. Wake

Excited to share that I’m joining @dfinity! Thrilled to dive deeper into what I love—building cross chain tools and libraries, creating demos, running workshops, and advocating for the future of #ICP. Let's go!

Building cross chain ETH applications on the #InternetComputer has a huge potential! In this video I describe how you can get started using ETH wallets to securely interact with ICP smart contracts.

Caffeine just leveled UP! 🚀 Build an Art Deco team page based on a sloppy wireframe, a downloaded style reference, and a bunch of photos! 🎉 New feature: Multimodal support means you can upload more than one image (or other data) at a time. Caffeine will interpret the images

Caffeine can now access the internet! If you need help finding a data source, a code snippet, or some design ideas, just ask - @caffeineai will look it up. Prompt: Build me a weather dashboard for Stockholm, Sweden. First, find an open API that provides both current conditions

VetKeys is one of the coolest upcoming #ICP features! In short, vetKeys allows smart contracts to hold secrets, which is.. a pretty big thing! Check out my demo allowing Ethereum users to send encrypted files to each other! 👀 Live demo: h62xu-2iaaa-aaaal-qshoq-cai.icp0.io

Should I build a SUI wallet on ICP? Not because it is hard but because it is easy.
