A new ouroboros in the technology landscape has emerged: There is now an AI tool designed to effectively “undo” AI writing.
Sinceerly is a Google Chrome extension that allows users to edit AI-generated (or even human-written) emails. The primary goal of this tool is to introduce imperfections that are typically eliminated by AI writing tools and to modify some of the recognizable AI text “tells,” such as the phrase “not just X, but Y.” Em dashes also fall into this category, which is unfortunate for those who appreciate their use. As a seasoned writer, I find them invaluable, yet it seems they have become a telltale sign of AI writing. Nonetheless, Sinceerly is here to eliminate the em dash, as prominently stated on its official website.

The tool operates in three distinct modes: subtle, human, and CEO. Each mode progressively alters the tone of the text, with “CEO” mode even foregoing proper punctuation while humorously adding “Sent from my iPhone” as an afterthought.

Sinceerly offers three free email rewrites within Gmail. For a monthly fee of $4.99, users can enjoy unlimited rewrites, seamlessly switch between the available modes, and even cache their results for quick access later on.
According to the website, Ben Horwitz, a partner at the venture capital firm Dorm Room Fund, is the mastermind behind Sinceerly.
The notion of utilizing AI to generate text, only for another AI tool to humanize it, seems quite absurd. However, it might perfectly encapsulate the prevailing sentiments about AI-generated copy in 2026. Recently, the major publisher Hachette withdrew the novel Shy Girl due to concerns that it was AI-generated and/or poorly crafted.
Perhaps it would simply be easier to—gasp—compose text by yourself.
