I write a lot with Claude Code these days. Code, of course, but also docs, emails, briefs, and the occasional blog post. It is very good at the first draft and clunky at the second. If I want to fix one paragraph, I have to paste the whole thing back into a terminal and then hunt through the reply for what actually changed. After about the tenth time doing that, I realized I did not want a better prompt. I wanted a better surface: somewhere I could point at a single sentence and say “this, but better.”
So over a few quiet hours on vacation, I built one. It is a small web app that drives the local claude CLI right from the browser. There is no new API key and no new bill. It just reuses the subscription I already pay for.
The whole thing runs on three verbs. You describe what you want, and it streams a draft into a clean reading column. You comment on any span of text, the way you would scribble a note in the margin of a printout. Then it revises. That last step is the part I care about most. It comes back with surgical find-and-replace edits, so every word I did not touch stays byte-for-byte identical. Nothing lands on a server I do not control. It all saves locally, and I can export to HTML, PDF, docx, or slides when I am done. I wrote this post in it.
The barrier to building your own software has been lowered quite considerably in recent years. vanished.
I want to be honest about what this is. It is a v1. A weekend toy, not production software. There are rough edges I have not sanded down and a few corners I cheerfully cut, because I was the only user I was building for.
But the speed is not really the point, and neither is the tool. The point is what the weekend itself proved. I did not set out to ship a product. I had an annoyance, a few free hours, and an AI pair programmer, and at the end of it I had a piece of software shaped exactly to the way I work.
Not lowered. Vanished. The boilerplate, the part that used to eat the first three weekends before you got anywhere interesting, is mostly gone. What is left is the part that was always the good part: knowing what you actually need, and having the taste to shape it. If a tool you reach for every day is almost right, that gap used to be a roadmap. Now it is a weekend. Build the thing.
It is open source, warts and all. Take it apart, build your own, or build a better one. I would love to see what you make.
