When a Shopify bill arrives, the author messages Hermes Agent in Telegram: check email for the latest Shopify bill, download it, add it to the Xero AXIS account, and mark it paid from the ST director account. What used to take about five minutes of manual download/entry becomes a ~30-second chat. Video of the run is attached.

Everything is approved before it goes out.
A New York filer put W-2s, 1099s, bank statements and last year's return in one folder and wrote a task.md telling Claude Code to act as a tax preparer.

A user had their Grok Bot email their electricity retailer for a full year of usage data in 5-minute intervals (over 100,000 readings), price it against all 1,019 residential plans on their network, and model their Powerwall 3 battery and 17.7 kW solar on each one. It also read the fine print on the winning plan.
Planning to buy e-bikes for his family for Christmas, a user wanted to add one more bike he hadn't budgeted for.

A user booked two China Eastern tickets through a booking site, ticketed by Gotogate. After the airline changed the schedule, they asked for a full refund, got written confirmation of 15 to 20 business days, then sent 8 complaint emails over ten days and heard only that the refund would come when the airline paid.

He says the subscription has paid for itself for about three years or more.
A user was about to buy a new NAS for $1,000. Grok Bot said only one drive was bad, so a $194 replacement would let RAID rebuild the NAS. He says it also chose a better, cheaper Medicare supplement and gave tips on cheaper homeowners insurance.

Meta Muse logged into both insurers, compared rates for each other's cars, combined the policies on one carrier and cancelled the other, saving $168/month (over $2K a year).
