Type a sentence and see it rewritten with emoji in place of the words that have one. Works in reverse too.
Every emoji in the Unicode set ships with official keywords - the words your phone's emoji search matches against. This tool uses that list as its dictionary, so it recognises around four thousand terms, and prefers longer matches: "police car" becomes ๐ rather than ๐ฎ followed by ๐.
Switch the direction to go the other way and get the name of each emoji in a string back as words.
