Slabline is a tool for graded-card resellers. This kit has everything you need to write about us — facts, quotes, logos, screenshots, and contact info.
Slabline turns a photo of a graded slab into a draft eBay listing — the seller reviews and publishes. Reseller takes a photo (or drops a folder of photos). Slabline OCRs the cert label, pulls a live competing listing from eBay as a price reference, fills the title and item specifics, and queues the listing for review. The repetitive part — the typing — is gone.
It's a PWA, not an app store app — installs to home screen on iOS, Android, or desktop. The Starter plan is free up to 20 listings/month. Pro is C$19 / US$15 per month for unlimited listings, real-time comp pricing on every listing, bulk reprice + bulk end, CSV export, and the full insights dashboard. Marketplaces: eBay.ca and eBay.com.
"Resellers don't have a margin problem, they have a friction problem. Slabline removes the friction so the margin shows up."
"We're graded-only on purpose. Raw cards are a different animal — different photography, different condition logic, different pricing variance. We'd rather do graded perfectly than both poorly."
"PWA was a non-decision. The audience is power users on their phones, in their basements, at the post office. They don't want to wait on Apple to approve a release for a typo fix."
