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.

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.
