rewr.it for Chrome
A side panel that does two things. It tells you whether a piece of writing reads as machine-written, and it puts the words back in your own voice. Right-click a selection anywhere, or press the shortcut, and it picks up what you are writing and puts the rewrite back where it came from. In Gmail and LinkedIn it also finds the composer on its own.

Check, before anything is sent
Paste a draft, or grab the composer you are in. A reading appears above it: how machine-shaped this reads, and the patterns behind the number. It runs in the panel, so nothing leaves your machine, no account is involved, and there is no daily limit — there is no record to make.
Rewrite, in one click across
The same text box feeds both jobs, because the sequence people actually run is “is this obviously AI? … then fix it”. Press the button and the rewrite streams in — you never paste it twice.
See whether it actually worked
The rewrite arrives with the same scorer’s verdict on both versions — Machine tells 47 → 6 — and it says so when a rewrite came out worse. Names, numbers and dates that went missing or appeared are listed.
Put it back, or don’t
Insert writes it back into the box you took it from — a Gmail composer, a comment field, a plain textarea — replacing your selection if that is what you grabbed. Undo is there for thirty seconds. Copy always works, everywhere.
Checking never leaves your browser. The scoring runs in the panel — the same code this site runs at /detect — so text you only check is never sent anywhere. It works with the network off.
Rewriting sends the text you asked to rewrite, and nothing else. Your drafts are not stored, here or on your machine: the panel forgets everything when you close it, and the only thing kept on your device is your API key.
On Gmail and LinkedIn it can read the message you are composing and write a rewrite back, when you ask it to. It reads no other part of those pages.
On every other site it is not running until you call it. Right-click a selection or press the shortcut, and that click is what grants it the page — for that tab, until you navigate away. It reads what you selected, or the box you are typing in, and nothing else. There is no standing access to withdraw, because none was taken.
It also reads the address bar’s host name — mail.google.com, not the full address — to guess what kind of writing you are doing. That guess is made in your browser.
Email merlynn@gmail.com. A real person reads it.
The extension documentation covers setup, what each control does, and the two or three things that are worth knowing before they surprise you. What is stored, in full, is on the privacy page.
If the panel says there is no composer while you are looking at one, reload the tab — and tell us, because that is a bug rather than a step.
