Field Notes/Always-On Agent

Price Drops, Stock Alerts, Flight Deals โ€” Monitored 24/7

January 17, 2026 ยท 2 min read

You tell your agent: "Watch the Sony XM5 headphones. Let me know if they drop below $300."

Nine days later, your phone buzzes:

Sony XM5s just dropped to $279 on Amazon. Lowest I've seen. Want me to keep watching or are you pulling the trigger? ๐ŸŽง

You didn't check a single website. You said one sentence, and nine days later, it delivered.

How It Works

Your agent creates a scheduled task โ€” checking every hour, every few hours, or daily depending on urgency.

  • Searches the web for the current price
  • Records and compares to your threshold
  • If nothing changed? Stays quiet. No spam.
  • Price crosses your threshold? Instant message โ€” whether it's 10 AM or 2 AM

ChatGPT can look up a price once. But tomorrow? Next week? A flash sale at 2 AM? It has no idea. Chatbots do lookups. Agents do monitoring.

It's Not Just Headphones

The same mechanism watches almost anything:

  • Flight prices โ€” "Vancouver to Tokyo in March. Alert me below $800."
  • Hotel rates โ€” "Park Hyatt for anniversary weekend. Let me know if a deal comes up."
  • Restock alerts โ€” "That LEGO set keeps selling out. Watch for restocks."
  • Concert tickets โ€” "Radiohead reunion tour. Any city, any date."
  • Rental listings โ€” "2BR in Kitsilano under $2,200." New listings appear at random โ€” your agent catches them early.

Same pattern every time: describe what to watch, set a threshold, and the agent checks until something matches.

Why This Needs an Always-On Agent

Price monitoring requires three things a chatbot doesn't have:

  • Persistence โ€” keeps running between conversations. Checks prices at 3 AM because it was running at 3 AM.
  • Scheduling โ€” does things on a timer without being prompted. A chatbot can't schedule future actions.
  • Memory across time โ€” remembers yesterday's price to know if today's changed. A chatbot starts from scratch every conversation.

Set It and Actually Forget It

The value isn't just catching a deal. It's freeing you from the work of watching. No more daily tab-opens, price-checks, context-switches. One more thing off your plate.

Tell your agent what to watch. Go about your life. When something changes, you'll know โ€” not because you checked, but because your agent was watching the whole time.

ChatGPT answers questions. Your agent runs processes. Some things in life โ€” price drops, restocks, flight deals โ€” need a process, not an answer.
