Browser and Gmail

Connect WATERMARK SLAYER

Use one revocable connect key with the browser-wide Chrome extension or the native Gmail add-on. Text is sent only after an explicit action and is not retained.

Loading Gmail compose settings…

Install the browser extension

The Chrome Web Store item uses the public ID dpamnmeohgngdkaaeogpdblhndeblnlf. Until the current version is approved, testers can load the reviewed package unpacked.

Build hosts/gmail with pnpm --filter @watermark-slayer/gmail-host build.
Open chrome://extensions or edge://extensions, turn on Developer mode, and choose Load unpacked.
Select the hosts/gmail/dist folder.
Confirm the extension ID is hcplddpjpcmlpepkdjigbhcgdbjkmfkb.
Paste a connect key in the extension popup.
Highlight text on a webpage to Rewrite it, or open Gmail for the full compose workspace.

The selection bubble runs locally. Selected text is sent only after Rewrite. On Gmail, the compose workspace skips quoted history and signatures. It never calls the Gmail API or reads your inbox.

Use the native Gmail add-on

Install WATERMARK SLAYER from Google Workspace Marketplace when its listing is published, then paste the same connect key in the add-on home card. Gmail does not expose highlighted draft text to native add-ons, so paste text into the card, review the result, and choose Insert at cursor or replace selection.

Connect keys

Create a one-time connect key, then paste it in either client. Browser and Gmail actions require a paid plan or remaining bonus submissions. Your Gmail address does not need to match this account.
