How we check value
Identify the exact card
Match the player, set, parallel and grade. Use photo checks for unclear titles.
Compare relevant evidence
Compare matching cards using the sources included in your plan.
Include the buying costs
Include shipping and estimated fees. Confirm the marketplace total.
Know the limits
Limited evidence means less reliable estimates. Profit and authenticity are not guaranteed.

Live deal detection
Every listing you scan gets checked against real recent sales and flagged BUY, GOOD DEAL, or NEAR DEAL, with no manual comping.
eBay + Vinted
Works on both marketplaces, with landed cost, shipping and fee estimates built in.
AI photo verification
When a title alone isn't enough to confirm a card number or parallel, Sleever can read it straight from the listing photo.
Watchlist & shared deals
Save any card for later, and see deals other Sleever users have already found, all from one dashboard.

Your first scan, step by step
PC and Chrome required. Request the beta extension before subscribing.
Request beta access. Email Denis to get the extension and installation instructions.
Install the extension. Follow the supplied instructions in desktop Chrome. Keep the extension files in their installation folder.
Connect your account. Sign in to the dashboard and extension with the same account, then choose your plan.
Run your first scan. Open an eBay or Vinted listing or search page. Use the Sleever panel to scan, review the evidence and save cards to your watchlist.
Why am I not finding any deals?
Not every search finds a deal. Here are the common reasons.
The price is already close to market value
The price, shipping and fees leave too little margin.
There is not enough reliable evidence
Too few matching sales can prevent a reliable estimate.
The card cannot be matched confidently
Unclear titles, photos or grades can prevent an exact match.
Your search needs another angle
Try another player, set or marketplace. Add the year or parallel to narrow your search.
No deals, or no completed scan?
Zero deals can be a valid result. If scanning fails, check the extension, sign-in, plan and daily allowance.

A few things before you start
Does Sleever work on my phone?
No. PC with Chrome only.
What cards and marketplaces does it cover?
Sleever focuses on football / soccer trading cards and scanning eBay and Vinted. Matching depends on the card and available evidence. Marketplace availability can vary by country. MySlabs is an additional evidence source on First Team and Ballon d'Or, not an extra scanning marketplace.
What do the plan limits mean?
Scans and AI photo checks have separate daily limits. See Account for usage.
How does the free trial work?
First Team offers one 7-day trial for eligible accounts, then monthly billing unless canceled. Other plans are billed from day one.
How do I cancel or change my plan?
Go to Account → My plan → Manage billing.
Does a deal verdict guarantee a profit?
No. Check the evidence, final costs, condition and seller before buying.
What if I need help installing or scanning?
Contact Denis with the marketplace, your browser version and a description of what happened. Do not send passwords or payment details.
