Create a Marketplace Radar with AI in Minutes
TL;DR: You can create a marketplace radar with AI by typing what you want in plain English, like “Herman Miller Aeron chairs under $300 within 25 miles.” BigFlippa’s assistant reads that, shows you a preview of the exact searches it will run across Facebook Marketplace and Craigslist, and you confirm. No dropdown maze, no fiddly filters. This guide walks through every step, plus what the preview stage is actually doing behind the scenes.
What does it mean to create a marketplace radar with AI?
A radar is a saved watch order. It tells BigFlippa what listings to look for and pings you when a match shows up, usually within about 5 minutes of the listing going live.
The old way of building one felt like filling out a tax form. Pick a category. Pick a subcategory. Set a min price. Set a max price. Choose a radius. Toggle condition. Repeat for every variation you cared about. Fine once, tedious the tenth time.
Creating a marketplace radar with AI flips that around. You just say what you want, like you would tell a buddy who does your shopping. The assistant turns your sentence into structured searches and shows you what it plans to run before anything goes live.

How do you describe a radar in plain English?
Type the way you’d talk. The more specific you are, the tighter the results, but you don’t need to be fancy about it.
Here are a few examples that work well:
- “Used road bikes, 54cm to 58cm frame, under $400, within 30 miles of Austin”
- “PS5 consoles under $350, good condition or better”
- “Mid-century dressers and credenzas, solid wood, no particleboard, under $200”
- “Nintendo Switch OLED, under $200, ready to pick up this week”
What happens at the preview step?
This is the part people skip past in other tools, and honestly it’s the part that saves you from junk alerts. Before your radar goes live, the assistant shows you a preview of the actual searches it built from your sentence.
You’ll see how it interpreted your price ceiling, your radius, the condition, and which platforms it will watch (Facebook Marketplace and Craigslist). If it guessed wrong, say “drop the price to $250” or “only within 15 miles” and it adjusts. No going back to square one.
Think of it as a receipt before you pay. You get to eyeball what the machine understood and correct it in one line, rather than discovering a week later that your radar was pulling in the wrong stuff the whole time.
Why is this better than the old click-through wizard?
The wizard approach isn’t broken, exactly. It works. But it front-loads a bunch of decisions before you’ve even seen a result, and it makes setting up five related radars feel like a chore.
Chatting lets you batch it. “Watch for Tacomas, Rangers, and Frontiers under $12k within 50 miles” gets you there in one go. Each BigFlippa radar supports up to 3 search targets, so a single conversational radar can cover a small cluster of related searches instead of one per line.
And here’s the part I actually care about most: every alert lands with an upfront profit estimate. Market value versus asking price, right there in the notification. So you’re not just faster to the listing, you already know whether it’s worth the drive.
How to create your first radar, step by step
Start the 7-day free trial, then:
- Open the assistant and type what you’re hunting for in one sentence.
- Read the preview. Check the price ceiling, radius, and condition it inferred.
- Correct anything with a quick follow-up (“make it 20 miles”).
- Confirm. The radar goes live and starts watching Facebook Marketplace and Craigslist.
- Wait for alerts. Each one comes with a profit estimate so you can decide fast.
How many radars should you run?
Start with one or two while you get a feel for the alert flow. It’s tempting to spin up ten radars on day one, but you’ll drown in pings and stop reading them, which defeats the point.
Once you know which categories actually convert into flips for you, add more. The whole thing runs $10 a month, so scaling up doesn’t punish your wallet. Some folks keep a couple of “always on” radars for their bread-and-butter items and swap in seasonal ones (patio furniture in spring, snowblowers in fall).

Frequently asked questions
How do I create a marketplace radar with AI?
Type what you’re looking for in plain English, like “used dressers under $150 within 20 miles.” BigFlippa’s assistant turns that into structured searches, shows you a preview, and creates the radar once you confirm.
Can I edit the radar if the AI misreads my request?
Yes. At the preview step you can correct anything with a short follow-up, such as “lower the max to $200” or “only within 10 miles,” and the radar updates before it goes live.
Which marketplaces does a radar watch?
Every BigFlippa radar watches both Facebook Marketplace and Craigslist, and sends alerts, usually within about 5 minutes of a matching listing being posted.
Do alerts really include a profit estimate?
Yes. Each alert shows an upfront estimate comparing market value to the asking price, so you can decide whether a listing is worth pursuing without extra research.
