KartIO frequently asked questions

A Mac and Windows app for people who sell trading cards and sports cards. It is a channel manager: one inventory listed on several platforms at once (Vinted, eBay, Cardmarket, CardTrader and, in the US, TCGplayer), kept in sync, with prices and listing texts made from a photo of each card.

In the UK, Ireland and the rest of Europe: Vinted, eBay, Cardmarket and CardTrader. In the US: eBay, TCGplayer and CardTrader. Some countries also get their big local marketplace (see Where to sell). For Facebook, Whatnot and Voggt KartIO prepares the texts and photos to post.

Each card keeps one record per platform. When it sells (the sync brings the sale back, or you mark it sold), KartIO flags its other listings and takes them down in one click: deleted or ended where the platform allows, hidden where it can only hide, and listed for you to remove by hand where KartIO cannot reach.

Each platform gets the language its buyers search in: local ones such as Vinted in your country’s language, international ones (eBay, Cardmarket, CardTrader, TCGplayer) in English. The card’s own language (English, Japanese, German…) is written into the title.

In Europe from Cardmarket, in the US from TCGplayer, and for sports cards from what sold on eBay. KartIO keeps them in sync with the latest market prices, converts them to your currency and applies your own rules. Your prices never change unless you press Apply.

Pokémon TCG, One Piece Card Game and Riftbound (recent sets), and sports cards: NBA, WNBA, EuroLeague, NFL and soccer, Panini Prizm, Select, Donruss, Adrenalyn XL and more, PSA/BGS/SGC slabs and sealed boxes.

Not for recognition: the AI runs on your computer. Your photos are only uploaded to the listings you publish.

First your computer’s own text recognition reads the card in a fraction of a second; when the text does not settle it, a vision model that runs on your computer through Ollama takes over (the KartIO Launcher installs it). No account or key is needed and there is no cost per card. Stronger computers get a larger, more accurate model.

About half a minute per card on an M-series Mac or a PC with an NVIDIA graphics card. It runs in the background: drop in 100 cards and carry on.

No. You log in once in each platform’s panel inside the app, or connect eBay through its own sign-in page; KartIO never sees or stores your passwords.

No. One subscription includes every platform, every category, AI recognition, prices and sync.

The app is in English, Greek, German, French, Italian and Spanish. Listings are written in nine languages: those six plus Dutch, Portuguese and Polish.

Two with the same account. For a third, the Launcher asks you to sign out one of the others; you can also do it from your account page.

From your account on this site or in the KartIO Launcher → "Manage subscription", any time. The app works until the end of the period you paid for, and your data is never deleted.

Most cards are recognised right the first time. Those the AI is unsure about are flagged ⚠️, so you only check those. A clear photo, one card per shot, makes the biggest difference.

Yes. The AI reads the language the card is printed in and KartIO matches it by its number, writes the language into the title and applies your price factor for that language. Japanese, Korean and Chinese cards are always flagged for you to check.

Not on an Apple Silicon Mac. On Windows an NVIDIA card with 8 GB is recommended; without one the AI runs on the processor, several times slower.

Pokémon, One Piece and Riftbound, with the sets of recent years (adjustable), and sports cards.

Yes. KartIO reads the card’s language, matches it by its number and writes the language into the title; your price factor for that language is applied. Japanese cards are flagged for you to check.

No. You log in once inside each platform’s panel, like in a browser, or connect eBay on its own sign-in page. KartIO never stores a password.

Yes, that is the point. Each card keeps one record per platform (listing, price, status). When it sells on one, KartIO takes it down from the others.

Vinted, eBay, Cardmarket and CardTrader in the UK, Ireland and across Europe; eBay, TCGplayer and CardTrader in the US. Some countries also get their big local marketplace: the "Where to sell" page lists every country.

No. Cardmarket, CardTrader and TCGplayer only sell trading card games, so KartIO sends sports cards only to the platforms that take them, such as eBay and Vinted.

By card, through Stripe. KartIO never sees or stores your card details. Invoices are in "Manage billing".

The app works until the end of the period you paid for and then locks. Your data (cards, photos, Excel) stays on your computer and is never deleted.
