CoScripter
CoScripter (formerly Koala) is a discontinued a browser-based macro recorder developed by IBM Research. Implemented as an extension for the Mozilla Firefox browser, it records user actions and saves them in semi-natural language scripts. The scripts made are saved in a central wiki for sharing with other users. CoScripter aims at end-users through the use of programming by demonstration, a technique to create automated tasks without using a programming language. See also
