Features

Everything you need to move
inventory faster.

No manual data entry. No screenshot-and-retype. No alt-tabbing. Avarus does the work, you click Publish.

One-click posting

A "Post to Facebook" button appears on every AutoTrader listing card. Click it — Avarus opens the Marketplace form fully filled in a new tab.

AI descriptions

Compelling Marketplace copy generated instantly from the vehicle spec — tuned to your dealership's voice. Fully editable before you post.

Automatic photo upload

Up to 20 photos downloaded from AutoTrader and injected straight into the Marketplace upload field. No drag-and-drop, no screenshots.

Posted badges

Already-posted listings get a colour-coded badge on AutoTrader — green for recent posts, amber after 3 days. Never waste time re-listing a car you've already posted.

Speed & tone controls

Pick posting speed (conservative → fast), mileage units, and description voice. Match your workflow and your local market.

Smart model line PRO

Detects specialty builds — Shelby, Roush, Hennessey, Rocky Ridge, Alpina — from the dealer description, and writes the correct model automatically.

Posting queue

Add multiple listings to a queue and run them back-to-back. Avarus paces each post, prompts you to review, and advances automatically.

Inventory Audit PRO

Checks every car you've posted against AutoTrader — flags price changes, mileage updates, and vehicles removed from the lot. Keeps your Facebook listings compliant with FTC CARS Rule requirements.

From the lot floor

Built with dealers who post every day.

Cut my posting time from 15 minutes a car down to under a minute. Posted our whole weekend inventory on a Friday afternoon before anyone else left the lot.

The AI descriptions actually sound like me. Every other tool writes the same generic copy — with this one I edit maybe one line before I hit publish.

Roadmap

What's coming next.

Avarus is in active development. Here's what's in the pipeline — and what just shipped.

Live in v1.0

4 shipped

Chrome notifications

Desktop notification the moment an audit detects a price change or a removed vehicle — no need to open the extension.

Duplicate detection

Warns you before opening a new Facebook listing if the same VIN is already in your audit log. No more double-posts across team members.

Manual mark-as-posted

Posted a car outside Avarus? Mark it manually so the audit log and duplicate detection still track it correctly.

Export audit log

One-click CSV export of your full posting and audit history — useful for FTC CARS Rule compliance documentation.

Coming soon

Fix-all

After an audit, hit one button and Avarus opens each out-of-sync Facebook listing and updates the price and details for you.

Price-drop alerts

Get notified when AutoTrader drops a price below what you posted on Facebook — update before a buyer spots the mismatch.

CarGurus & Cars.com support

Expand beyond AutoTrader. Post directly from CarGurus and Cars.com inventory with the same one-click flow.

FAQ

Common questions.

Does this post to Facebook automatically, or do I have to do anything?

The extension fills in every field and uploads your photos, but you always review the completed form before it goes live. You click Publish. Auto-publish is available as an optional setting for experienced users, but it's off by default.

Will Facebook or AutoTrader flag my account for using this?

The extension mimics normal human browsing — it opens real tabs in your browser, uses your logged-in accounts, and adds randomized delays between every action. It never uses bots, headless browsers, or API workarounds. Thousands of manual copy-paste posts look identical to what this extension does.

Do I need a special Facebook account or Business Manager?

No. You just need to be logged into Facebook in Chrome — the same personal account you already use. The extension posts directly to Facebook Marketplace under your account exactly as if you typed everything yourself.

Can I use this for any vehicle on AutoTrader, or only my dealership's inventory?

It works on any AutoTrader dealer inventory page. Navigate to your dealership's listings on AutoTrader, and the Post to Facebook button appears on every car card automatically.

What happens to the photos?

Photos are downloaded from AutoTrader directly to your computer and uploaded to Facebook from there. They never touch our servers. Original order is always preserved — photo 1 stays photo 1.

One of my listings filled in wrong. What do I do?

The form is fully editable before you publish — change anything you want directly on Facebook before clicking Publish. If a field consistently fills incorrectly, contact support and we'll fix it.

Can two salespeople at the same dealership both use it?

Yes, but each salesperson needs their own account and subscription. Listings are tracked per account — if two reps share a login, duplicate detection and audit history won't work correctly. Pro tip: both of you post the same car and you double your dealership's Marketplace exposure.

What is the Inventory Audit and do I need it?

The audit checks every car you've posted to Facebook against the current AutoTrader listing. If the dealer changed a price or removed a vehicle after you posted, the audit flags it so you can update Facebook before a buyer spots the mismatch. The FTC CARS Rule requires your advertised price to match what you can actually sell the car for — this keeps you compliant automatically. It's a Pro feature.

What happens when my free trial ends?

After 10 free postings your account is paused — no listings will process until you subscribe. Your audit log, post history, and settings are saved and waiting. Subscribe any time to pick up exactly where you left off.

Does this work on Mac and Windows?

Yes. It's a Chrome extension — it works on any computer running Google Chrome, regardless of operating system.
