Try an example

Built for patient buyers

Start now. Catch what gets listed next.

Spotter Otter records when your Spotter begins, checks only the newly posted window, and remembers each eBay item so the same listing does not alert you twice.

◎

New-listing alerts

Get notified when a sold-out, rare, or currently missing item appears as a new matching listing.

⌁

Starts from now

Existing eBay inventory is not treated as a new find. Alerts begin when you create or update the Spotter.

✦

AI checks for the right match

Go beyond matching keywords. Our AI checks what is actually being sold and your requirements to help skip unwanted chargers, accessories, parts, and wrong models.

↗

You stay in control

Alerts show the listing details and send you to eBay. Spotter Otter never buys automatically.
