I built a browser extension that scores my AI prompts before I hit enter

I kept noticing the same thing: my first prompt to ChatGPT was almost never the one that worked. I'd send something half-formed, get a mediocre answer, then spend three more messages fixing what I should've said the first time.

So I built a thing to catch that at the source.

It's a browser extension. While you're typing in ChatGPT, Claude, Gemini, or Copilot, it reads your draft and gives it a score out of 100 — plus the two or three specific reasons it's weak (no output format, vague ask, missing context, that kind of thing). If you want, one click rewrites it. It also warns you if you're about to paste something sensitive like an API key or a client name.

One design decision I care about: the scoring runs locally on your machine. Your prompt only leaves your browser if you actually click a rewrite button. I didn't want to build another thing that quietly ships everything you type to a server.

It's early and honestly still rough in places. It's free while I'm in beta — I mostly want to know if it's useful to anyone besides me.

Two things I'd love feedback on:

1. Does a "score" even make sense to you, or would you rather it just fixed the prompt silently?

2. What's the AI tool you'd want it to work in next?

Link's in the comments. Happy to answer anything about how it's built.
