Three steps from inventory
to live listing

No training, no setup. If you can open Chrome, you're ready.

Install the extension

Add MarketFill to Chrome from the Web Store — one click, no configuration required. Works on any Windows or Mac computer.

Open any vehicle page

Navigate to a vehicle on your dealership website and click the MarketFill icon. The AI reads the page and extracts all listing details and photos automatically.

Review and post

MarketFill pre-fills the Facebook Marketplace form: price, year, make, model, mileage, description, and images. Review, make any edits, and hit post.

Built for the way
dealers actually work

Facebook compliant

Posts as a normal Marketplace listing from your own account. No automation API, no ban risk. Designed to stay compliant long-term.

AI field extraction

GPT-4o reads your inventory page and extracts VIN, mileage, make, model, year, colors, and body type — even from unstructured pages.

Works on any dealer site

No DMS integration needed. If your inventory is on a webpage, MarketFill can read it — VAS, CDK, DealerSocket, or custom sites.

You stay in control

Every listing goes through you before it posts. Review description, swap photos, adjust price — MarketFill fills the form, you make the call.

Secure by default

Your account credentials never leave your browser. MarketFill uses standard Chrome extension APIs — no passwords stored on our servers.

Fast and lightweight

No page-slowing scripts injected site-wide. MarketFill only runs when you click. Sub-second extraction on most inventory pages.

Simple, transparent pricing

No contracts, no setup fees. Cancel anytime.

Common questions

MarketFill is a Chrome extension that reads your dealership's inventory pages and automatically fills out Facebook Marketplace vehicle listing forms — price, year, make, model, mileage, exterior and interior color, body type, description, and photos. You review the pre-filled form and post. What used to take 10–15 minutes per vehicle now takes under a minute.
Yes. MarketFill fills the listing form the same way a human would — it does not use Facebook's API, no automation hooks, no bulk-posting bot. Every listing goes through your hands before it publishes. We target Marketplace only (not Groups), which keeps account risk minimal. We monitor Facebook's policies and update accordingly.
MarketFill is designed to work on any dealer website — VAS, CDK, DealerSocket, Dealer.com, custom sites, and more. The AI reads the page text and image data directly, so no integration or DMS connection is required. If the vehicle details are on the page, MarketFill can find them.
Yes, absolutely. There are no annual contracts and no cancellation fees. Cancel from your account dashboard at any time and you won't be charged again. Your access continues until the end of the current billing period.
No. MarketFill never asks for or stores your Facebook credentials. It works inside your already-logged-in Chrome browser — the same way you'd fill out any form normally. Your session stays on your computer. We only store your MarketFill account email to manage your subscription.
