Rocket

In plain words

Rocket is a Mac application that enables Slack-style emoji input across the operating system. Users can type colon-based emoji codes (such as :rocket: or :tada:) in any application, and Rocket automatically converts them to emoji characters. The tool brings the quick emoji-insertion experience familiar to Slack users to the broader Mac ecosystem, making it useful for anyone who wants faster emoji access while writing messages, emails, or documents.
