Grok Bot Turns a $199-a-Year Flight Monitoring Service Into a Free One

Grok Bot has recently been put to a new use: someone had it run a complete flight-price monitoring system, for free.

This service was originally the core selling point of Going (formerly Scott's Cheap Flights), which charges $199 a year to watch for business-class deals and mistake fares. Now Grok Bot does the same job at zero cost.

The way it works isn't complicated. Every night it checks the routes you set, compares each flight's price with the usual price for that route, and only alerts you if the price actually drops. It won't push a pile of junk notifications at 3 a.m.; it only pings you when the drop is big enough.

Users only need to configure three lines of instructions:

1. "watch flights from my city to these 3 places, any class"
2. "check every night at 3am and compare to the usual price"
3. "message me only if a fare drops 30% or more, with the link"

Then just let it run.

The video shows the actual running interface. grokbot is already in a connected state, the monitoring list is empty, and it is waiting for the user to tell it what to watch. The whole process requires no extra code, no API key, and is completed conversationally.

Choosing 3 a.m. has its reasons. One commenter said: "a fare that's gone by 7am is just a rumor"—a fare that disappears by 7 a.m. is just a rumor. The poster replied that this is exactly why 3 a.m. was chosen. By the time humans wake up and start scrolling on their phones, bug fares are often already gone. The machine gets up first and catches the message; humans just click the link during the day.

If you don't want to watch only flights, the poster also has a more complete article explaining how to plug this logic into a team of five bots running 24/7 without sleep: https://x.com/i/article/2113653510596169728

The tool itself is free, but its value doesn't depend on the tool—it depends on how you use it.
