GmailClass
GmailClass is an email classifier that adds custom colorful labels to messages directly inside the Gmail inbox.
GmailClass is a browser extension that labels emails in the Gmail inbox based on user-defined categories. Users describe their categories, configure labeling rules, and see clear color-coded labels directly next to their emails. The system relies on Jev to evaluate messages against custom descriptions and assign probability thresholds for label visibility. Multiple labels can apply to a single email since each category is checked independently. Users set up the extension by installing it in the browser, providing a TypeSafe API key, choosing their categories, and reloading Gmail.
