Install Auction Bid Assistant
Search 7 auction platforms at once, save lots as you browse, export as PDF — free for Chrome, Firefox and Safari.
What does it do? The extension searches 7 auction platforms simultaneously (the-saleroom, EasyLive, eBay, Invaluable, NumisBids, iCollector and LiveAuctionWorld) from a single popup. It adds a 🔨 Save Lot button letting you save lots from all 7 platforms, search results and Featured Auction catalogues — export your shortlist as PDF or CSV. It never modifies pages or places bids.
What does it do? The extension does three things: searches 7 auction platforms simultaneously from a single popup; adds a 🔨 Save Lot button so you can save lots from search results, Featured Auction catalogues and all 7 auction platforms — export as PDF or CSV; and pairs with the Auction Bid Assistant app to feed the auctioneer's asking price to your bid ladder in real time during live auctions. It never modifies pages or places bids.

How to Use During a Live Auction
Save lots before the sale
Search across platforms from the popup, browse Featured Auctions, or visit lot pages on the-saleroom.com and EasyLive and tap 🔨 Save Lot. All saved lots are stored with image, estimate and URL. Export as PDF or CSV anytime — or open the extension popup, download the list, and paste into ⬆ Bulk Import in the app.
Open the auction in another tab
Log in to the-saleroom.com or EasyLive and open the live bidding page. Keep this tab open alongside the app.
Tap Go Live in the app
The bid ladder fills your screen. As the auctioneer calls prices, the asking price and current bid highlight on your ladder automatically — so you always see your total cost at every increment.
Mark Won / Lost / Pass
When a lot finishes, tap the result. The app advances to your next lot. When all lots are done, review your results, see sale totals, and export to CSV.
Common Questions
Does the extension place bids for me?
No. It only reads publicly visible data from the auction page — the asking price and lot number. You still bid on the auction platform as normal. The app is a visual calculator.
Which browsers are supported?
Firefox, Chrome, and Safari on macOS — all free, all one-click installs from their respective stores. Firefox is recommended as the easiest. The app itself works on all browsers and devices without the extension; you just update the current bid manually instead of having it auto-update.
I use Safari on Mac. How do I install?
Install from the Mac App Store — one click, then enable the extension in Safari → Settings → Extensions. macOS only; an iOS version is in development.
Which auction platforms does it work with?
For search: the-saleroom, EasyLive, eBay, Invaluable, NumisBids, iCollector and LiveAuctionWorld — all searched simultaneously. For the Save Lot button while browsing: the-saleroom.com and EasyLive. You can also save lots from search results and Featured Auction catalogues on any platform. The live bridge (optional) works with the-saleroom.com and EasyLive. More platforms are being added regularly.
Why is the Bridge indicator grey?
Make sure: (1) the extension is installed and enabled, (2) you have the auction site open in another tab in the same browser window, (3) the auction page has finished loading. The bridge sends a heartbeat every 3 seconds — wait a moment and it should turn green.
The Chrome extension disappeared after restarting
Chrome Web Store extensions update automatically and stay enabled after restarts. If it has disappeared, just reinstall it from the Chrome Web Store.
Is my data safe?
All data stays in your browser. The extension never sends anything to any server, never accesses your login credentials, and never modifies any web page. Read the full privacy policy →
