It replaces the traditional list of emails with a focused view that automatically bundles related messages, such as newsletters and promotions, so you can handle them in bulk. You can snooze tasks for later, pin important conversations to the top, and use a built-in calendar to manage your schedule without leaving the app.

The platform integrates advanced AI to help you write better emails and find information instantly. You can ask the AI assistant to summarize long threads, draft replies in your unique voice, or search through your entire history using natural language. It works directly with your existing Gmail account, ensuring your data stays synced across all your devices while providing a much faster, more organized experience.
