A new ouroboros in the tech world has emerged: There’s now an AI<\/a> tool to “undo” AI writing. <\/p>\n

Sinceerly<\/a> is a Google Chrome extension to edit AI-generated (or human-written) emails. The aim is to add in errors that are typically scrubbed away with AI tools and change some of the obvious AI text “tells,”<\/a> like the phrase “not just X, but Y.” Em dashes fall into the latter category, too \u2014 but as a longtime writer, I’m fond of them and abhor how it’s apparently become a signal of AI. Regardless, Sinceerly will kill the em dash, as it states on its website. <\/p>\n

The tool has three modes: subtle, human, and CEO. Each render text more and more casual, where “CEO” mode doesn’t even have correct punctuation but does tack on “Sent from my iPhone,” of course.<\/p>\n

Sinceerly is free for three email rewrites and works within Gmail. But if you want to pay $4.99 per month, you get unlimited rewrites, can switch instantly between modes, and can cache results so you can reopen them instantly. <\/p>\n

Ben Horwitz<\/a>, an investment partner at venture capital firm Dorm Room Fund, created Sinceerly, according to the website.<\/p>\n
