Built around a modern listing workflow
Where the platforms differ most for a high-volume eBay seller.
| What matters | CardLuma | Kronozio / KronoCard |
|---|---|---|
| Platform / device fit | Browser-based workflow with mobile-friendly web access and phone upload via QR code. | Windows desktop workflow. Kronozio lists Microsoft Windows, TWAIN scanner, internet connection, and Kronozio account as requirements, and says Kronocard does not work on Mac or mobile “for the moment.” |
| Scanning / image capture | Upload card images in batches from desktop or phone; front/back images can be combined automatically for eBay listings, and a whole batch scanned backwards can be swapped front-to-back in one action. | Scanner-first workflow. Kronozio says Kronocard auto-associates front/back images and auto-crops cards from flatbed or feeder scanners. |
| AI card identification | 10M+ card database, 99.8% claimed identification accuracy, and sub-5-second identification. | AI documentation with 92% claimed accuracy on Kronozio’s homepage; Kronozio also says it can document over 1,200 cards per hour. |
| Supported card categories | Sports, 165+ TCG/CCG titles, and non-sports trading cards in the same workflow, with serial-numbered CCG/TCG cards identified and populated automatically. | Sports plus selected TCG categories. Kronozio’s AI coverage page lists sports categories and TCG support for Lorcana, Magic, One Piece, and Pokémon. |
| eBay item specifics | 20+ eBay item specifics auto-filled from identification results, including player, year, set, card number, sport, team, parallel, RC, HOF, autograph, serial, graded/ungraded, and more. | Kronozio says it automatically populates item-specific fields on eBay, but the public pages reviewed do not present the same 20+ field-level breakdown. |
| Pricing / sold comps | Real eBay sold prices, recent sales, active listings, Market Movers lookup, and per-card P&L are available inside the workflow. | Kronozio’s getting-started guide says an automatic pricing feature was being worked on but was “not ready yet,” and directs users to a pricing helper workflow. |
| Rules & automation | Reusable rules for store categories (primary and secondary, including a team-matches-category rule), shipping policies, Best Offer minimums and auto-accept set globally or by price band, description templates, scheduling, and more. | Public Kronozio pages emphasize spreadsheet editing, advanced navigation, inventory filters, shipping, and eBay sync rather than customizable if-this-then-that listing rules. |
| eBay publishing & sync | Direct eBay publishing, eBay CSV export, scheduled listings, variation listings, ad campaign sync, active/sold inventory management, bulk delist/relist, and P&L tracking. | Kronozio says sellers can list 10,000+ cards at a time and that its bidirectional eBay listing tool updates inventory as cards sell. |
| Inventory management | Browser-based single inventory with active/sold listings, inline editing, bulk edits, bulk delist/relist, sync, search, sort, and customizable columns. The batch table fills the screen, with drag-to-reorder columns and adjustable widths. | Strong inventory database, search, status filters, and bidirectional eBay sold sync; best fit for sellers who want a dedicated Windows/scanner inventory setup. |
| Pricing model | Scan-volume plans. $10/mo for 1,000 scans, $20/mo for 2,500, $38/mo for 5,000, $71/mo for 10,000, and $99/mo for 15,000. Full platform on every plan, unlimited listings, and no expiring add-on scans. | Kronozio lists $8/month for 500 AI documented cards per month, 500 managed cards on eBay, unlimited cards in Kronocard, and an optional $24/month Export Add-On. |
| Trial / evaluation | 14-day trial, no credit card required. | Free evaluation/download available; the public pages reviewed showed inconsistent free AI-documentation limits (50 on one download page, 250 on another product page), so verify the current limit before relying on it. |
| Channel workflow | eBay-first, with direct Shopify integration and Whatnot-ready inventory via CSV export, plus seller-controlled inventory workflows. | Scanner-first workflow with marketplace/export capabilities depending on setup. Kronozio announced that the Kronozio Marketplace would close on October 14, 2025, and said it was refocusing on AI-powered collection management and platform integrations. |
Beyond scanner-first workflows
Kronozio / KronoCard is built around scanner-first inventory documentation. CardLuma is built around scan-to-sale operations: identify the card, create clean listing data, price it, apply seller rules, and reuse that data across eBay, Shopify, and Whatnot workflows — direct eBay publishing, a direct Shopify integration, and a Whatnot-ready CSV export for live selling.
