Who is it for

During a live broadcast there is no time to manually copy chat messages. BCO gives the operator a single click — the message appears on-air with fully controlled styling. Perfect for studios, events, sports broadcasts and conferences.

Click a chat message — it instantly appears on the overlay. Click again to hide. Used messages are grayed out.

Full style control

Colors, fonts, themes, presets, enter/exit animations, text scale, glow, border-radius.
