OLXPert is a browser extension built for active OLX.pl sellers managing dozens or hundreds of listings. It adds the tools OLX doesn't give you — right inside the pages you already use. What you get

Color-coded tags — Create custom tags with 8 colors to categorize listings. Filter by tag, see untagged items, stay organized.
Private notes — Attach notes to any listing for reminders, buyer details, or context. Search across all notes instantly.
Message templates — Save ready-made replies with variables like {listing_title} and {price}. Insert them into OLX chat with one click.
Listing templates — Save a listing's structure (title, description, category, parameters) as a reusable template. Create new listings in seconds instead of filling forms from scratch.
Quick duplicate — Copy any existing listing to a new form with one button. All fields transferred automatically (except photos).
Expiration tracking — See which listings are about to expire with color-coded urgency badges (green → amber → red) directly on your inventory.
CSV export — Download all your listing data (notes, tags, views, expiration dates) as a spreadsheet-ready CSV file.
