Discord Mention Formatter
Paste an ID, pick what it belongs to, and get the exact syntax Discord turns into a clickable mention: users, roles, channels, custom emoji, slash commands and timestamps. Batch mode formats a whole list of IDs at once.
Enable Developer Mode (Settings → Advanced) to copy IDs. Emoji names are 2 to 32 characters (letters, digits, underscore); the name in the tag must match the emoji's real name. For slash commands the ID is the application command ID, which you get by right-clicking the command in the picker. Setting up your first channels and roles? Follow the server setup guide.
