Features

Everything you need to move
inventory faster.

One extension reads three sources, fills every field, and keeps your listings honest. Built with dealers who post every day.

One-click posting

A "Post to Facebook" button on every AutoTrader, CarGurus & Cars.com card. Click it — the Marketplace form opens fully filled in a new tab.

AI descriptions

Compelling copy generated from the vehicle spec, tuned to your voice — Casual, Friendly, Professional, or Spanish. Fully editable before you post.

Automatic photo upload

Up to 20 photos downloaded from the source and dropped straight into the Marketplace upload field — in original order.

Posted badges

Already-posted cars get a colour-coded badge on your inventory pages — green for recent, amber after 3 days. Never re-list the same car.

Posting queue

Queue multiple cars and run them back-to-back. Avarus paces each post, prompts you to review, and advances automatically.

Smart model line

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

Inventory Audit

Checks every posted car against its source — flags price changes, mileage updates, and delisted vehicles. Keeps you FTC CARS Rule compliant.

Speed & tone controls

Pick posting speed, mileage units, and description voice. Match your workflow and your local market.

Pricing

Simple, per-seat pricing.

Start free — your first ten listings are on us. No credit card to try. Cancel any time.

FAQ

Common questions.

Does this post to Facebook automatically?

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 an optional setting for experienced users, off by default.

Will Facebook flag my account for using this?

The extension mimics normal human browsing — it opens real tabs in your browser, uses your logged-in account, and adds randomized delays between every action. No bots, headless browsers, or API workarounds. It looks identical to manual posting.

Do I need a Business Manager account?

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

What happens to the photos?

Photos are downloaded from the source listing directly to your computer and uploaded to Facebook from there. They never touch our servers, and original order is always preserved.

What is the Inventory Audit, and do I need it?

The audit checks every posted car against its current source listing. If a price changed or a vehicle was removed after you posted, it flags it so you can update Facebook before a buyer spots the mismatch — keeping you FTC CARS Rule compliant. It's included in your plan.

What happens when my free trial ends?

After 10 free postings your account pauses — your audit log, post history, and settings are saved. 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. It's a desktop tool.

Roadmap

What's coming next.

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

Chrome notifications

Desktop notification the moment an audit detects a price change or a removed vehicle.

Duplicate detection

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

Manual mark-as-posted

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

Export audit log

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

CarGurus & Cars.com

Post straight from CarGurus and Cars.com inventory too — the same one-click flow as AutoTrader.

Fix-all

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