SellFast on Chrome: Fill Vinted, eBay and Subito Listings from a Side Panel

With the website, the routine is: generate the listing on SellFast, copy each field, switch tab, paste into the marketplace form. The Chrome extension shortens the last part.

What the extension does

The SellFast extension opens as a side panel in Chrome, next to the marketplace page.

You upload up to 5 photos of the item in the panel and choose platform (Vinted, eBay or Subito.it) and language (Italian, English, French, Spanish or German).
SellFast AI generates a title, description, hashtags and an estimated price range.
On the marketplace's sell form, you click Fill form: the extension fills title, description (with hashtags) and price (the middle of the estimated range).
You check every field, add photos, category and details, and publish.

The extension does not publish for you. If a field can't be filled automatically (for example eBay's description editor in some layouts), the text is copied to your clipboard so you can paste it.

How to install and connect it

Open the Chrome Web Store page and click "Add to Chrome".
On the SellFast website, go to your dashboard and generate an API key (it starts with sf_).
Paste the key in the extension's side panel.
Open the sell page on Vinted, eBay or Subito.it and use the panel.

Credits

The extension uses the same credits as the website: 1 credit per generated listing. New accounts get 5 free credits; you can buy more at any time.

Supported sites

The extension works on Vinted (IT, FR, ES, UK, DE, BE, PL sites), eBay (.it, .com, .co.uk, .fr, .de) and Subito.it. Marketplaces sometimes change their forms: if a field isn't filled, copy it from the panel and let us know.

Why we built it

The most common request we received was to avoid switching tabs. The extension doesn't add new AI features: it puts the same generator next to the form you're filling.
