Five A.I. helpers were asked to write a "tough e-mail," ... one was the clear winner

Guess "who?"

Excerpt: "There are lots of AI helpers out there now. But only one can write emails as well as you.

To figure out which artificial intelligence assistant is worth your time and money, I set up an old-fashioned bake-off. I asked five bots to draft five kinds of difficult work and personal emails. Then I brought together a blue-ribbon panel of communications experts to judge all the emails — blind.

To see whether the bot emails were distinguishable from human ones, I also had the judges score emails written by me.

One hundred fifty email evaluations later, one AI did outperform this human. But the judges also thought one of the most popular AIs right now sounded so robotic, you might want to avoid it."
