One click on any supported product page. AI writes your title, description, and fills every item specific — photos included, fully drafted and ready to publish.
Listing an item used to be a chore. Now it's a moment.
Everything runs automatically the moment you click the icon.
Navigate to a listing you want to sell on eBay. The extension activates automatically on supported store pages — starting with Amazon, with more platforms coming soon.
One click scrapes the product title, description, bullet points, specifications, and all available images from the page.
Claude AI reads the eBay category's live item specifics, then writes an optimised title, compelling description, and selects the correct value for every attribute dropdown — in a single pass.
Your eBay draft is fully populated: title, description, photos transferred, and all item specifics filled. Just review and hit Publish.
No copy-pasting, no re-typing, no tab-switching.
Claude writes an eBay-optimised title within the 80-character limit, prioritising searchable keywords from the source listing.
A clean, buyer-facing description is generated from the product's bullet points and details — no fluff, just what matters.
Product images are fetched directly from the source page and attached to your eBay draft — no manual downloading or re-uploading.
The extension reads every attribute dropdown in the eBay category and tells Claude — which picks the right value for each one automatically.
Hidden eBay attribute sections are expanded automatically before AI enumeration, so no optional field is ever skipped.
The extension calls Anthropic's Claude API directly using your own key. No middleman server, no data stored outside your browser.
