Cardstash
Catalogue and value your card collection — unlimited, in the browser
Type what you can read off a Pokémon, Magic, Yu-Gi-Oh! or Lorcana card, confirm the ranked match, and it lands in your stash with a condition-adjusted value, set completion and a chase list. Free, no account, no scan limit.
Stored in your browser only. Nothing you do in the web version is sent to our servers. Clear your browser data and it's gone — so export a backup from the in-app menu if you want to keep it.

What you can do in Cardstash on the web
Confirm-first matcher, never a silent guess
The same normalised-name + collector-number ranking the iPhone app runs on OCR text, shown as candidates with a confidence score — “Pikachu ex 238/191” resolves to one card, nonsense resolves to nothing.
Scan tray, then add the whole batch
Confirmed cards stack in a tray with a running session total, exactly like scanning card after card on the phone, and commit to your stash in one tap.
Condition-adjusted value
Every listing is priced from the 2026-06-19 snapshot times the app's own condition multipliers — Mint ×1.15, Near Mint ×1.00, LP ×0.85, MP ×0.60, HP ×0.40, Damaged ×0.25 — across variant and quantity.
Set completion with Have / Need
Sets you have started are ranked by how close you are, counted against each set's real printed total (165 for 151, 191 for Surging Sparks), with a per-set Need list.
Insights, chase list and cost basis
Cumulative collection value over time, value split by game, your most valuable listings, unrealised gain against what you paid, and the high-value cards you are still missing from sets you collect.
CSV and JSON export
One row per listing with unit value, total value, cost basis and date added — or a full JSON backup. Everything stays in this browser.

Questions
Is the web version of Cardstash free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the Cardstash iPhone app?+
There is no camera OCR here: you type the card name and collector number the camera would have read, and the same matcher ranks the candidates. Card photos are not stored — the iPhone app saves your own scan photo as each card's picture; the web version draws a tinted placeholder instead. The bundled catalog is a slice of the phone app's 180,000-card database: 151 and Base card-for-card, plus the highest-value cards of 170 other Pokémon, Magic, Yu-Gi-Oh! and Lorcana sets. Set completion still counts against the real printed total. Prices are an estimate from a dated 2026-06-19 snapshot (pokemontcg.io / TCGplayer) and Lorcana carries no price in that snapshot — always verify a high-value card yourself. Everything is stored in this browser only, so clearing site data erases your stash; export a JSON backup first.
