About this extension

Messages that an AI assistant posts on someone's behalf carry a “Sent using Claude” line. This add-on collapses those messages in the Slack web app (app.slack.com) so only the sender's name and timestamp remain, plus a toggle to show or hide the full message.

Options: turn it off, remove matching messages entirely instead of collapsing them, or change the match pattern.

It only changes what you see in your own browser. It collects no data and makes no network requests.
