The AI searched my Gmail, found my subscriptions and cancelled ClassPass

He gave the AI a prompt to search 24 months of his Gmail, 2,812 emails, and list the subscriptions he was still paying for. With his approval it cancelled ClassPass at 9,900 yen a month, a saving of 118,800 yen a year, and a confirmation email arrived to prove the cancellation went through.

How it works

  1. Gives the AI a prompt to search 24 months of Gmail for receipts and billing emails
  2. It checks 2,812 emails and lists his live subscriptions with prices
  3. He approves cancelling ClassPass
  4. The cancellation goes through and a confirmation email arrives

Why it’s worth knowing

One prompt turned two years of email into a short list he only had to approve. The cancellation he had been putting off was done and confirmed the same day.
