What's in it.

Alerts

Stack pictures, GIFs, videos with see-through backgrounds, sounds and styled text, then drag, resize and rotate them on a live preview. Start from a template or a blank canvas.

Chat overlays

Design your chat box: frames, fonts, badges, 7TV, BetterTTV and FrankerFaceZ emotes. Cut it into slices to wrap around a webcam, or bend it to fit a frame.
