The reason for creating &#8216;Regards&#8217; was simple but most people can relate to when receiving emails. &#8220;I was very upset by the AI \u200b\u200bmess in my inbox,&#8221; Horwitz said. <i>TBPN<\/i> podcast. &#8220;People will email me; it all looks exactly the same.&#8221;<\/p>\n<p>The extension is free for some initial uses before requiring $4.99 for further use, but according to Horwitz, this product is unlikely to be his main source of income, as he sees it more as a piece of social commentary rather than a tool.<\/p>\n<p>There are three types of settings provided by Sincerely which are designed according to a particular type of flaw. There is an option called &#8216;subtle&#8217; where all unnecessary words are removed, some phrases are changed to contractions, and in the first line, a deliberate mistake will be made.<\/p>\n<p>However, when implementing the above changes Human Mode will make writing conversational. In the third option, called &#8216;CEO Mode&#8217;, the entire message will be written in lowercase, and only the essential information will remain. If the email lacks a signature, &#8220;Sent from my iPhone&#8221; will still be added.<\/p>\n<p>Horwitz actually identified something strange about how people are using the tool in practice. &#8220;People are copy-pasting; first they&#8217;re doing the prompt, then they&#8217;re copy-pasting their prompt into the email, and then they&#8217;re using &#8216;Sincerely&#8217; to make their email not look like AI,&#8221; he said. &#8220;Humans are using AI to make AI more human.&#8221;<\/p>\n<p>That loop prompts, generates, and humanizes represents a communications arms race that no one side of the inbox now fully controls.<\/p>\n<\/p><\/div>\n<p><script type=\"text\/javascript\">\n      \/*var images = document.getElementsByTagName('img');\n      for(var i = 0; i < images.length;
