SHOP SMARTER — free, no account needed Open a listing on eBay, Poshmark, Grailed, Mercari, Depop, or Vinted and click "Get condition read." GradeThread's AI reads the listing photos and gives you: • A 1–10 condition score with a confidence level • A flag when the seller may be over-grading the item • Condition-adjusted price fairness • Which photos to ask the seller for before you buy SELL FASTER — for FlipDesk sellers Cross-post your FlipDesk drafts to Poshmark, Mercari, and Grailed. The new-listing form is prefilled in your OWN logged-in browser tab — you just review and click List. YOUR SESSIONS STAY YOURS No "cookies" permission and no access to your marketplace accounts. Condition Check sends only the public listing photos already on the page to GradeThread's grading service; nothing is stored on our servers, and your recent reads stay on your device. Cross-listing runs entirely in your browser — GradeThread never sees your marketplace password or cookies. Buyer research is free for everyone. Seller cross-listing unlocks with an active FlipDesk plan at gradethread.com. ## Rankings - #148,264 — Overall - #9 — poshmark - #125 — depop - #185 — upgrade ## Permissions and access ### Permissions - `storage` - `activeTab` - `alarms` - `contextMenus` ### Host permissions - `https://gradethread.com/*` - `https://*.gradethread.com/*` - `https://*.poshmark.com/*` - `https://*.mercari.com/*` - `https://*.grailed.com/*` - `https://*.vinted.com/*` - `https://*.vinted.co.uk/*` - `https://*.vinted.fr/*` - `https://*.vinted.de/*` - `https://*.vinted.es/*` - `https://*.vinted.it/*` - `https://*.vinted.nl/*` - `https://*.vinted.pl/*` - `https://*.vinted.be/*` - `https://*.vinted.at/*` - `https://*.vinted.cz/*` - `https://*.vinted.sk/*` - `https://*.vinted.lt/*` - `https://*.vinted.pt/*` - `https://*.vinted.se/*` - `https://*.vinted.ro/*` - `https://*.vinted.hu/*` - `https://*.vinted.lu/*` - `https://*.vinted.hr/*` - `https://*.vinted.gr/*` - `https://*.vinted.dk/*` - `https://*.vinted.fi/*` - `https://*.facebook.com/*` ### Content script matches - `gradethread.com` - `*.gradethread.com` - `*.ebay.com` - `*.ebay.co.uk` - `*.ebay.de` - `*.ebay.ca` - `*.ebay.com.au` - `*.ebay.fr` - `*.ebay.it` - `*.ebay.es` - `*.ebay.ie` - `*.ebay.nl` - `*.ebay.at` - `*.ebay.ch` - `*.ebay.pl` - `*.ebay.be` - `*.poshmark.com` - `*.poshmark.ca` - `*.grailed.com` - `*.mercari.com` - `*.depop.com` - `*.vinted.com` - `*.vinted.co.uk` - `*.vinted.fr` - `*.vinted.de` - `*.vinted.es` - `*.vinted.it` - `*.vinted.nl` - `*.vinted.pl` - `*.vinted.lt` - `*.vinted.cz` - `*.vinted.be` - `*.vinted.at` - `*.vinted.ro` - `*.vinted.hu` - `*.vinted.sk` - `*.vinted.pt` - `*.vinted.se` - `*.vinted.lu` - `*.vinted.hr` - `*.vinted.gr` - `*.vinted.dk` - `*.vinted.fi` - `poshmark.com` - `mercari.com` - `www.mercari.com` - `www.grailed.com` - `www.facebook.com` - `*.facebook.com` ## Safety - **Risk impact:** Very high risk impact - **Risk likelihood:** High risk likelihood ### Analysis details - Request access to the following domains: gradethread.com, ebay.com, co.uk, ebay.de, ebay.ca, com.au, ebay.fr, ebay.it, ebay.es, ebay.ie, ebay.nl, ebay.at, ebay.ch, ebay.pl, ebay.be, poshmark.com, poshmark.ca, grailed.com, mercari.com, depop.com, vinted.com, vinted.fr, vinted.de, vinted.es, vinted.it, vinted.nl, vinted.pl, vinted.lt, vinted.cz, vinted.be, vinted.at, vinted.ro, vinted.hu, vinted.sk, vinted.pt, vinted.se, vinted.lu, vinted.hr, vinted.gr, vinted.dk, vinted.fi, facebook.com - This extension was recently updated in the past month.
