A tiny buddy that lives on your desktop.
Bitty is a little pixel creature that sits at the edge of your screen. When your AI is busy, click it and a quick game pops up. Press Esc and it steps aside.
Small, quiet, always nearby.
Stays out of the way
It sits in a corner or the middle of a screen edge, clear of the menu bar, Dock and taskbar. Drag it anywhere and it glides to the nearest spot, and remembers it when you plug in or unplug a monitor.
Follows you around
Switch desktops and your buddy comes too: macOS Spaces, Windows virtual desktops and Linux workspaces. (On Linux with Wayland, switching desktops closes an open game.)
Click to play
Click the buddy and a small quick-play window opens with a challenge ready. Or press Option+Shift+B on a Mac, Alt+Shift+B on Windows and Linux, from any app. You can change the shortcut.
Esc means back to work
One press of Esc saves your round and closes the game. Prefer it tucked away? Hide the buddy and play from the menu bar or tray icon instead.
It reacts while you play: cheers when you nail one, wobbles when you miss, and salutes when your wait timer runs out.
Pick your buddy.
Every buddy plays exactly the same. They just have different personalities (and opinions about your score).

SOONYour buddy levels up with you.
