About the project / Updated July 15, 2026

Input that viewers can see and remember.

Overlay Cat is a desktop streaming tool and browser preview for creators who want keyboard, mouse, and gamepad actions to become part of the scene.

Why Overlay Cat exists

Important stream actions often happen outside the camera frame. Overlay Cat turns those actions into a responsive Bongo Cat overlay, helping viewers follow shortcuts, clicks, movement, and game controls without adding a clinical key logger to the layout.

One character and style system

The website preview and desktop app use the same PNG Sprite character packages. Creators can compare six cats and five hardware layouts in the browser before preparing an OBS or TikTok Live scene in the desktop app.

Built around useful previews

The browser demo responds only while this page is active. Production capture belongs in the desktop app, where a creator can keep the character reacting while another application or game is focused.
