    I made a Chrome extension to clean up your Gmail inbox locally▲96

    Hi everyone, My motivation for building this was to address the trouble of mass unsubscribing from unwanted emails and deleting bulk emails while ensuring privacy and control over the process. With this Chrome extension, emails are not sent to any external servers. All calls to the Gmail API happen locally on your device. Feedback and suggestions are welcome!
