Thread Context Cards — Context for Gmail

What is Thread Context Cards — Context for Gmail?

Thread Context Cards adds inline hover cards to Gmail. Hover over any sender name and see recent conversations, attachments, upcoming meetings, past events, Drive files, and email statistics — without leaving your inbox. Unlike other Gmail tools that clutter your interface or require sidebar panels, we work as a simple hover. The card appears in under 300ms, loads core data in under 1 second, and progressively fetches additional context in the background.
