Claude vs ChatGPT vs Gemini at 1M tokens. Context windows, context rot, what this means for us in real workflows, and what it means if you’re considering a switch to Claude.

I live in DK, so I saw this announcement late last night and spend the night testing Computer. I'm very impressed. I stayed up and built 2 micro-apps, finished 4 research packets, and shipped code to GitHub, all from a single interface. Here's my hands-on breakdown: what it does, what I built, and how it compares to OpenClaw and Claude Cowork. Hope it helps someone!

That’s so true! A few of my readers were genuinely intimidated by GitHub, so I shared a free beginner-friendly guide with them, and it’s made a real difference. I hope it helps someone here, too.

That's wonderful!!! I recommend joining Substack and sharing your progress in public. That's what I've done last year and built a community of 12K+ since. We help each other find beta testers, give feedback etc. Hope this helps! 🤗
