Facebook's new Seller app turns a product photo into a marketplace listing

Meta launched Seller on July 24, a standalone app built specifically for people who sell on Facebook Marketplace, timed to the platform's tenth anniversary. The headline feature is the listing flow: a seller uploads photos of an item and Meta AI fills in the title, description, a suggested price, and the category, with a bulk-listing option for uploading several items at once. It's a narrow but genuinely useful automation — the tedious part of resale, writing a decent listing, handed to a model instead of a person.

Beyond the AI listing tool, Seller centralizes the operational side of running a Marketplace shop: a dashboard surfacing what needs attention (items to ship, buyers to respond to, listings to reprice), a unified inbox that organizes buyer messages by listing, inventory management, and performance insights covering views, clicks, and completed sales. Existing listings and message history sync in automatically, and anything created in the app still appears on Marketplace itself, where the buyers already are.

Meta paired the launch with Facebook Verified, a free identity check that only requires a selfie rather than a paid subscription, adding a checkmark badge visible across Marketplace, Dating, and Groups. The app is live now on the App Store for US users 18 and older, with Android and web versions still in testing. Meta says 430 million items are listed on Marketplace globally each month, across more than 1.1 billion active users — the scale that makes even a modest per-listing time savings worth building a dedicated app around.
