Some people on the internet can't even refer to people or things they don't like without gratuitously insulting them. NastyWriter automates this habit by automatically inserting insults before nouns as you are typing. Insults added by NastyWriter are highlighted in peach to distinguish them from your own text, and you can share the insult-ridden text as an image with the highlighting intact. You can remove or change any insults which don't fit in the context, to make sure your stream of nastiness is just right, even when it's just wrong. If there’s some text you want to nastify again and again, you can add a Siri shortcut to create a new nastified version of it in response to a voice command. In the Shortcuts app, you can also use the 'Nastify' shortcut to add insults to the result of another Siri command, or ask for a random insult.

Verdict
