So I have a webapp that is basically my OS. It has my Daily Overview, Mail, Calendar, Todoist Tasks, Dev Projects, News Curator, and Karpathy knowledge base, etc…all in one. On top of that, I have a chat agent orchestrated by LangGraph on the backend, so it can query and act across the different parts of my life. For example: “look at project xyz. I had an email with George from xyz company and he wanted a feature implemented. Look at the repo and tell me what is left on that feature branch. Break the deliverable down into 30-minute working blocks and add it to my calendar during my focus hours on wednesday.” I love what I built, but visually it still felt too much like a functional dashboard and not enough like a living personal operating system that was fun to use and visually stunning. So I set Fable to xHigh and ran it with some scoping guardrails I’ll leave out here:

You are a world-class product designer + front-end engineer. I’m testing what you can do. I want you to make my personal dashboard app, “BlaineOS,” look absolutely badass — more visually awesome, more alive, more fun to use every day. Be ambitious. Surprise me. A bold reimagining is welcome. What BlaineOS is A single-user personal command center. Modules: Overview, Mail, Calendar, Tasks, Projects, News, Knowledge — plus an AI assistant named “Alfred.” Today it’s a calm, keyboard-driven, monochrome-leaning dashboard (each module has a single monochrome glyph icon; there’s a g-then-letter hotkey scheme). It’s deployed and in real daily use. Stack Next.js 16 (App Router, React Server Components, Server Actions) React 19, TypeScript Tailwind CSS v4 Plain components + Tailwind (no component-library lock-in) The brief You have free rein over the look, feel, motion, and interaction design. Massive overhauls are on the table — new design language, new layout, new visual identity, ambitious motion, the works. Treat this as your portfolio piece.

Fable was able to completely overhaul my front end, make it absolutely stunning, and let’s just say it - more BADASS - across the entire project. The wild part is that it did the whole thing start to finish in less than 70% of my 5-hour window on the Pro Max 5x plan. A drop in the bucket. Based on my experience using Opus 4.6-4.8 for this kind of work, I’m pretty confident the same overhaul would have taken multiple 5-hour windows there. Fable just feels unusually efficient for ambitious frontend transformation work. I’m actually blown away right now. Anyone else have similar experience so far? submitted by /u/Optimal_Foundation46
