Add it
In the overlay editor: Widgets → Alerts & chat → Chat box. Drag it where you want it and resize it. The box is the area chat fills; older messages drop off the edge.See it before you go live
An empty chat box shows a hint on the canvas. To fill it:- Click Demo, then start Chat messages under Simulate. Fake chatters keep talking until you stop it.
- Or hit Send a test message at the bottom of the chat box settings.
- Or just type in your own Twitch chat. Real messages show up in the editor too.
Look
Pick a starting look, then tweak it:- Plain: text straight on your stream, with a shadow so it stays readable.
- Bubbles: each message on its own rounded background.
- Card: name on top, message below, full width.
Messages
- Layout: vertical (a normal chat column) or horizontal (one line per message, side by side, like a ticker). Switching to horizontal shrinks the box to one row and keeps its bottom edge where it was; switching back restores a normal column. To make the strip longer, change Frame width under Advanced, then Scale & crop. Dragging the corners scales the whole box, text included.
- Newest message: at the bottom (like Twitch) or at the top. In horizontal layout: on the right or on the left.
- Max on screen: how many messages stay up at once.
- Fade out: messages disappear after this many seconds. Off keeps them up until newer ones push them out.
- Animate in: fade, slide up, slide from either side, pop, or none.
- Animate out: fade, slide away, shrink, or none. Plays when a message fades out, so turn on Fade out to use it.
- Slide messages along: when a new message comes in, the others glide to their new spot instead of jumping. On by default.
- Badges and profile pictures: on or off.
What gets hidden
- !commands are hidden by default, so
!uptimespam stays off stream. - Bots: StreamWizardBot, Nightbot, StreamElements, Streamlabs, Moobot, Fossabot, WizeBot and Sery_Bot are hidden out of the box. Add or remove usernames, one per line.
- Deleted messages disappear from the overlay the moment a mod deletes them. Timeouts and bans remove that chatter’s messages, and clearing chat clears the box.
