Heart It

Heart It is an open-source desktop application for Windows that sends reactions during Microsoft Teams meetings. It is intended for people who want to respond in Teams using keyboard shortcuts rather than selecting reaction controls manually. The application runs from the Windows system tray while the meeting is in use.

Heart It supports five reactions: Like, Love, Applause, Laugh, and Surprised. Each reaction is assigned to a global hotkey from Ctrl+Alt+1 through Ctrl+Alt+5. These shortcuts provide a consistent way to send a reaction while keeping attention on the meeting.

The application uses Windows UI Automation to interact with Microsoft Teams. Because of this approach, it can send the selected reaction without requiring the user to switch windows. Its Windows-specific design places it in the desktop utility category, with a focused role for Teams meeting interaction.
