Checker Plus for Gmail
What Checker Plus for Gmail is
Checker Plus for Gmail is a browser extension for desktop Gmail use without opening the mailbox. It shows incoming messages and sender contact photos, then lets you receive desktop or voice alerts and listen to, read, archive, mark as read, or delete messages from its popup. Multiple Gmail and Google Workspace accounts are supported, with selected labels monitorable per account and separate sound, notification, and voice settings. Notification controls include sounds, spoken content, and display choices. Calendar tools and offline access are included. Optional AI tools can compose or reply from prompts using Google Gemini; they are disabled initially. For reply prompts, the specific thread passes through an encrypted proxy, and the developer says prompts and data are not logged or stored on its servers. OAuth 2.0 is used, and listed permissions cover mail.google.com data and notifications. Chrome, Edge, Firefox, Brave, Vivaldi, Opera, Comet, and Arc are listed as supported browsers. Core features are free, with optional contributions unlocking extras.
