This is a free Chrome extension with no "funny business". Unlike the leading extension, this one asks for only sensible, safe permissions. It uses a thesaurus to help you find emojis. For fun, try searching for colors like "green" and "red".
Not much to this one, but I do personally use it every single day. This lets you get emojis really easily. bind a keyboard shortcut and search for... well exactly what you think the emoji should be called: "magic" or "dragon" or whatever. It'll find it and let you copy it to clipboard. Use these mindfully to dress up your docs/emails.
