AI eBay alerts that check each listing against what you asked for

Why keyword alerts flood your inbox

An ordinary eBay alert, including a saved search, matches words. That sounds fine until you look at who else uses those words:

• Accessories borrow the item’s name. “Case for iPhone 16 Pro Max”, “Charger for MacBook Pro 14”, “Replacement strap for Garmin Fenix 7”. The seller is describing what the accessory fits, and the search can’t tell that apart from the item itself.
• Sizes are written a dozen ways, or not at all. A search for a men’s large jacket finds listings that say “fits like a medium”, size charts that list every size, and listings that put the size only in the item specifics.
• The right model with the wrong detail. 128GB when you wanted 256GB, a Wi-Fi tablet when you wanted cellular, the women’s version of a shoe.
• Things that aren’t the thing. Box only, manual only, for parts, a lot of ten, a photo of the item.

The usual fix is a long list of excluded words, and it cuts both ways. Exclude “case” and you lose the phone listed “comes with original box and case.” Don’t exclude it and you’re back to scrolling past cases. That’s the gap AI alerts are meant to close.

How AI alerts work on Spotter Otter

Spotter Otter is an AI eBay search tool and tracker in one: the AI helps write the search, then helps check what the search finds.

1. Describe it in your own words. Write it the way you’d tell a friend: iPhone 16 Pro Max, 256GB, unlocked, any color, used is fine. Add a maximum price; it’s required, and prices are before shipping.
2. Luna writes the search and the must-haves. The search uses the words that name the item. The must-haves are the facts that have to be true: here, 256GB and unlocked. If something in your sentence is unclear, she asks before the Spotter starts.
3. You confirm. Read what she understood. Change a must-have, remove one that’s only a preference, or add one she missed. Nothing is watched until you start the Spotter.
4. Each new listing is checked. From the moment you start, the Spotter watches new eBay listings and compares each one with your must-haves.
5. You get the ones that fit. Matches arrive by email and on your Alerts page. Open the listing on eBay and decide; Spotter Otter never buys or bids.

How must-haves are checked

Sellers write the same fact many ways, so each must-have is matched with the wordings sellers use, in the title and in the item specifics. Large is L, LG or Lrg. 30x32 is waist 30, inseam 32, whether the seller writes “30x32” or “W30 L32”. “256 GB” and “256GB” are the same storage.

Then there are three possible outcomes:

That last row is the important one. A listing that doesn’t say isn’t a wrong listing; it’s an unanswered question. Spotter Otter doesn’t throw it away and doesn’t pretend it’s confirmed. It shows it to you labelled Maybe match, in the email and on your Alerts page, so you can read the photos or message the seller.

Some must-haves can only be answered by the seller’s own words, like “includes the original box” or “no smoke odor.” Luna reads the listing for those. If the listing doesn’t mention it, that’s a Maybe too.

What “AI filtered” and “AI verified” mean here

People search for AI filtered and AI verified eBay alerts, so it’s worth being precise:

• Filtered means listings that state something different from your must-haves are left out before they reach you.
• Verified, here, means every listing that would become an alert is checked against your must-haves first.
• It does not mean authenticated. Spotter Otter checks a listing against what you asked for. It doesn’t authenticate or appraise items. For sneakers, watches, handbags and trading cards, look for eBay’s Authenticity Guarantee on listings where it applies, and remember the eBay Money Back Guarantee covers items that don’t match their description.

No filter is perfect. Sellers mislabel sizes, titles disagree with photos, and an item specific can be wrong. The goal is fewer near-misses and no silent guesses, not a promise that every alert is the one. Always read the listing before you buy.

An AI tracker, not a deal judge

If you searched for an AI deal tracker or AI shopping alerts, here’s what to expect. A Spotter tracks new listings that fit your must-haves at or under your maximum price. It doesn’t decide whether a price is a bargain or what an item is worth. To pick a sensible maximum, search the item on eBay and turn on the Sold items filter to see what it has actually sold for recently. The guide to eBay price alerts covers that step by step, and finding deals on eBay covers hunting below the usual price.

Write a sentence Luna can work with

• Name the item like a seller would. Brand, model and the detail that identifies it: Le Creuset 5.5 qt round Dutch oven, not “a nice red pot.”
• Say which details are must-haves. “Must be size 10; black preferred” tells her the size is a rule and the color is only a preference.
• Say what you don’t want, plainly. “Working, not for parts.” “The jacket, not just the liner.” You don’t need to guess the seller’s exact words.
• One item per Spotter. Two different items in one sentence make a muddled search. Make two Spotters.
• Check the must-haves before you start. If she made something a must-have that you’d happily skip, remove it, or you’ll miss listings that don’t mention it.
