## Description

twitch, kick + youtube live chat in one panel — read every stream you follow and reply into any of them without alt-tabbing. nobody else has to install anything. plus your own emotes in any channel: 5,000 free slots, no sub, no streamer setup. free.

• cross-platform multichat — twitch, kick + youtube live chat in one tabbed panel: per-channel tabs, mentions, twitch whispers, resizable + dockable to any edge. no account needed to read.

• your emotes, any channel — upload or import any emote (7tv, bttv, ffz, or your own) into a free 5,000-slot inventory. tab-complete a name and send — it renders in twitch + kick native chat and the overlay, any channel. one click imports a whole channel's emotes.

• 7tv / bttv / ffz — emotes, paints + badges render automatically, channel and global. runs alongside those extensions — this adds the portable emotes and cross-platform chat they don't do.

• keyboard-first — vim keybindings on twitch, kick + the panel, wysiwyg emote composer, message history, reply threading, instant filter of the live buffer by text or user.

• moderation + profiles — hover mod toolbar (ban/timeout/unban/delete), client-side automod, mute or block that carries a user across twitch and kick, profile cards with a searchable chat-log archive, one-click twitch clips.
