ListFlow Engine™

The Chrome extension that bridges your AutoTrader inventory and Facebook Marketplace — with every move triggered by you.

Coming soon to the Chrome Web Store. Sign up for early access.

What ListFlow Engine Does

Four things, done well. No feature creep, no background automation.

🔄

AutoTrader Inventory Sync

When you click Refresh on your dashboard, ListFlow Engine pulls your dealership's current inventory from AutoTrader's authenticated API — photos, VIN, specs, price. Every sync is triggered by you, never on a background timer.

📝

Facebook Marketplace Pre-Fill

When you're ready to post a vehicle, ListFlow Engine opens a Facebook Marketplace listing and fills in the details. You review the pre-filled form, edit anything, then click Post yourself on Facebook's native page.

✂️

Image Cropping & Reorder

Crop, rotate, and reorder your dealership's AutoTrader photos before they go to Facebook. Lead with your best shot; drop any you don't want on the listing.

✍️

5 AI Description Styles

Pick your default in Settings — Professional, Quick Stats, Seller Story, Dealer Post, or Top Features. Each ends with your own signature line. Override per-vehicle anytime by clicking Generate Description.

Built on Chrome's Security Model

No clever tricks. We use the same extension permission model every trustworthy Chrome extension uses — and we ask for as little as possible.

🔒 MANIFEST V3

Built on Chrome's current extension standard. No deprecated APIs, no legacy permission models.

🎯 SCOPED PERMISSIONS

Runs only on AutoTrader dealer pages and Facebook Marketplace listing pages. Your other browsing is untouched.

🔑 ZERO PASSWORD STORAGE

We never see or store your Facebook or AutoTrader login credentials. The extension works within your existing browser sessions on those sites.

👆 USER-TRIGGERED ONLY

No background timers, no silent activity. The extension acts only when you click Refresh, click Import, or click Post.

You Stay in Control

ListFlow Engine is assistive, not automatic. Scans run only when you click Refresh. Listings publish only when you click Post — twice, once in ListFlow and again on Facebook's own form. We never store your Facebook or AutoTrader password.
