Running a charity auction?
We built a tool for that.

AuctionTool.ai runs the whole evening from everyone’s phone: printed codes beside the lots, live bidding on the big screen, and settlement the same night.

One evening, three steps

Step 1

Codes beside the lots

Print a card per lot. Guests scan, see the work and the current bid, and bid from their own phone — no app, no account.

Step 2

Live on the big screen

Every bid lands on the screen in the room within a second. The auctioneer sets the pace; the tool keeps the score.

Step 3

Settled the same night

Winners pay before they leave; the organiser gets one overview and one payout. No spreadsheets the morning after.

For artists and galleries

You get asked every autumn to donate a work to a benefit evening. Now the same house that shows your art can run that evening too — and your work is shown the way it deserves: big, with your name, and a link back to your page.

Try it with a practice auction

Set up an evening in ten minutes, invite two friends and bid against each other. Free until you run a real one.
