It’s come to this! Sinceerly is a Gmail plugin that provides “AI to undo your AI writing.”
It adds typos, scrubs em-dashes, and plucks out “it’s not this, it’s that” AI tells. Creator Ben Horowitz calls it the “anti-Grammarly,” a tool to make your writing less polished. The app’s CEO mode hilariously trims messages down to a handful of words and adds “sent from iphone” to the end.
I tested Sinceerly by cold emailing 5 Fortune 500 CEOs. 4 CEOs replied. Of those replies, each was under 10 words. 2 replies had typos. One reply called me Larry (my name is Ben).
