We've all experienced the consequences of our own actions or words in a momentary lapse of self-control.
I have this idea for an app that reads what you type, like predictive text, Grammarly or spellcheck but looks for certain keywords. Then upon finding one of the keywords, prompts you to take a different approach.
For example, if I were to type, "Fuck you!" the app could send a pop-up message saying "Are you feeling angry or aroused?"
Depending on my response, the app could then suggest alternative wording. This would be educational, helping people expand their vocabulary, getting them to read a bit and generally also just learning to take a second to think before sending a message. But the approach needs to be entertaining. So, if I said that I am angry, the app could give me a Monty Python or Stephen Fry like paragraph to replace my expletive response. Or if I chose "aroused" the app could quote Oscar Wilde or Jane Austen.
Imagine being able to get rid of all the "haha", "lol", "what the fuck", "wow", "shit", "damn" and the rest of the overused, meaningless placeholders we mistake for conversation nowadays and actually getting access to some proper literature in everyday communications.
