CastChat

CastChat brings live text and voice chat to your TV or external display, letting you share conversations during media playback or presentations. CastChat connects your mobile device to compatible Chromecast, Smart TV, or DLNA receivers so that messages and moderated chats appear on-screen without interrupting playback.

Key features

Key features of CastChat include an on-screen chat overlay that displays messages and simple reactions over video or presentation content; voice-to-text support to convert spoken input into messages for quick hands-free interaction; moderation and privacy controls to manage participants, mute or remove messages, and restrict who can post; multi-device synchronization so conversations stay in sync across phones or tablets connected to the same session; and broad compatibility with common casting standards and many popular smart TVs.

How to use CastChat

To begin, open the app, select the target display, and start a session. Invite participants using a session code or network pairing, choose display and moderation settings, and send messages or use voice input. CastChat is intended for group chats during viewing, remote presentations, and events where on-screen interaction is helpful.
