HyperChat is a Discord bot that connects text channels together across servers. HyperChat also allows you to use custom and animated emoji from the HyperChat Emoji bank server, even without nitro. It also gets people to join your server, as an invite link is displayed at the bottom of each message.
To set up the bot, go to the dashboard Here, add the bot, click manage, select the text channel and you’re good to go! The prefix is hc!!, and to view all commands do hc!!help.
Alternative setup, invite the bot, then run hc!!setup in the channel you want linked. To unlink, do hc!!unmark.
