How much would you pay for a single AI killer app?
Hedge fund honcho Sam Leffell has views. I got to know Sam while researching ChatGPT’s predictive abilities. He uses that leading AI tool constantly for work and in his personal life.
He also tried Google’s Gemini earlier this year and became obsessed with a Gmail feature called Polish that uses AI to improve any email with at least 12 words in it. You just press Alt+H on Windows PCs, or Option+H on Macs, and Gemini swoops into action. (That’s polish, the shining process, not Polish the language).
Sam said this was the most useful Gemini feature. “Writing emails now takes a fraction of the time it used to,” he said. “I still make picky edits, but it’s a lot quicker and better.”
Here’s the wrinkle: He turned off his Gemini paid subscription after a while because, anecdotally for him, it was not as good as ChatGPT. Then, the Polish feature from his Gmail suddenly disappeared. Unacceptable!
“That surprised me,” Sam said. “So now I’m paying Google a certain amount each month, just to have this button to polish all my emails. That’s how valuable this is.”
The first paid tier of Gemini is $20 a month. That’s a lot for one feature.
