Can AI Help You Buy and Sell Secondhand?
Yes. AI makes a specific secondhand model easier to find, and you can connect your own AI assistant to Commonplace to search listings, quote delivery, and list items. Ari Kimmelfeld on Liftoff with Keith.
Listen to the episode: How Commonplace Is Reinventing the Secondhand Marketplace, Liftoff with Keith with Keith Newman, aired October 20, 2026. Listen on YouTube.
Short answer: Yes. AI is making it easier to find a specific model at the best price, as long as the listing is not locked inside one app. On Commonplace you can also connect your own AI assistant, such as ChatGPT or Claude, to search live listings, quote delivery to your ZIP code, and price and list what you sell. Payment stays with you: the assistant cannot take or send payments.
Keith Newman asked where the secondhand economy goes from here, in the age of AI, on Liftoff with Keith.
What Ari said
Well, I think secondhand shopping is just blowing up, and you're seeing this across many different categories.
Ari Kimmelfeld on Liftoff with Keith, at 22:15
Big and bulky is not getting any easier. So there's still somebody that needs to pick it up, pay this high value, offer a warranty, deliver it, install it. And AI is just making discoverability much better.

So if you're looking for the best price for a specific model, a specific brand, being discoverable and not stuck within an app like an OfferUp or a Facebook Marketplace really makes it discoverable for somebody's agent... to find it, be able to actually click and order it, and then there's low risk, so the agent is much more likely to actually place that order because you pay on delivery.

Why paying on delivery matters
Ari's point is that low risk makes an order easier to place, whether a person or an assistant finds the item. On Commonplace:
- A $1 hold reserves the item. Nobody else can buy it while it is held.
- It is inspected before pickup. A 30 to 50 point inspection, with a report you approve. If it is not right, cancel before pickup and owe nothing.
- You pay on delivery. On orders under $8,000, you pay the rest when it arrives.
- A warranty is included. A free two-month parts warranty.
Selling with AI
For sellers, Ari described listing a whole room from one picture:
You can easily take a photo of an entire room, whether it's a garage, whether it's a living room, whether it's a kitchen. We'll give you pricing suggestions automatically based on our price index, and you can list multiple products at once.

That is Sell Your Room. And with the AI connector, an assistant you already use can work out the right category, show what similar items list for, create a listing from your description and photos, and accept, counter, or decline offers. You see a preview of every change before it happens.

Can I use ChatGPT or Claude to sell on Commonplace?
Yes. Add Commonplace to your assistant with the AI connector. It can suggest a category and price, create and edit listings from your description and photos, and answer offers. Every change is shown as a preview and happens only after you confirm it.
Can an AI assistant pay for an item on Commonplace?
No. The AI connector cannot take or send payments, see your password, or change how you are paid. It can search live listings and quote delivery to a ZIP code.
What is Sell Your Room?
Take one photo of a room. Commonplace finds what you can sell, names each item, suggests a price, and lets you list the items you pick together. Try Sell Your Room.
