We make ChatGPT and Claude argue before a doubtful listing reaches us

When one AI isn't sure about an era, a price or whether a brand is real, it asks a second AI once with the same facts. If they agree, it goes in the draft. If not, you get both opinions in two lines.

The problem

One model's confident wrong answer looks the same as a right one. You either check everything or trust everything.

The workflow

  1. Define the triggers: uncertain decade, price outside the comps range or thin comps, any brand or authenticity doubt.
  2. On a trigger, the first agent sends the second one the item, the facts so far, what is already decided, and one specific question.
  3. One consultation per decision. If they still disagree, the seller gets both views in two lines and decides.
  4. A hard daily cap and a gap between calls so two agents cannot loop on each other and burn money.
  5. Both agents are read-only. A reply is advice, never permission to change a listing.

What happened

The review page got quieter. Most consultations agree and the draft just carries the answer. The handful that disagree are exactly the ones worth a human minute.

For your store

Our honest estimate from running this. Your store and numbers will differ.

What you need
Two AI chat apps, for example ChatGPT and Claude. Free tiers are enough to try it.
First try takes
A couple of minutes per doubtful item by hand. A day to wire up with a daily cap.
First step tonight
Next time you are unsure about an era, a price or a brand, ask the second AI the same question with the same photos and facts. Ask once.
After a week
You will see how often the two agree. The items where they disagree are the ones worth your own time.
