AI for auctioneers: cataloguing, valuations and buyer service
Auction houses spend most of their effort cataloguing: photographing, describing, researching and estimating lots. AI drafts lot descriptions from photos and notes, finds comparable past results and answers routine buyer questions, so specialists spend their time on attribution and valuation.
Start with cataloguing for one sale. It limits how many lots and sales you can run.
Where AI pays back first
More revenue
Catalogue more lots per sale and reply to buyers faster, which supports higher sell-through.
Lower costs
Reduce cataloguer hours per lot and the overtime before each sale.
Time back
Cut time spent on condition report requests and buyer emails.
Jobs worth looking at
| Job | How it often runs now | Where AI can help | What a person still checks |
|---|---|---|---|
| Lot descriptions | Cataloguers write each description by hand from the object. | Draft descriptions from photos, measurements and short notes. | Specialists confirm attribution, date and condition. |
| Valuation research | Past results are searched across several databases. | Summarise comparable results and price ranges. | The specialist sets the estimate. |
| Condition reports | Written on request for each bidder. | Draft reports from photos and cataloguer notes. | Staff confirm details before sending. |
| Buyer and shipping queries | Answered by email around each sale. | Draft answers from the catalogue and terms. | Staff approve. |
Houses use auction management software and bidding platforms such as the-saleroom, EasyLive or Invaluable, with AI cataloguing features starting to appear. Photo workflows matter most: consistent, well-lit images give AI drafts far better material to work from. Business AI assistants help with buyer emails and research summaries.
Different firms, different starting points
Fine art and antiques auctioneers
Specialist cataloguing. AI drafts, specialists confirm.
General and household auctioneers
High volume. AI speeds descriptions.
Commercial and plant auctioneers
Asset lists. AI helps listings and buyer queries.
Worked example
A regional auction house that catalogues faster
A regional house catalogues about 600 lots per monthly sale and often runs late.
Porters photograph each lot and cataloguers add short notes. AI drafts descriptions in the house style.
Specialists check every lot before publication. The house tracks lots catalogued per person per day.

Cataloguers may use free tools. Approve one.
Keeping data safe
Use business or enterprise AI accounts with model training turned off and a data processing agreement signed. Consignor details are confidential.
What each leader should do first
Owner or managing director
Start with cataloguing speed for one sale, and measure lots catalogued per person per day before and after.
Head of department or specialist
Set rules for attribution, dating and condition checks, and keep a list of AI errors to improve the drafting template.
Questions owners ask
Can AI write auction lot descriptions?
Yes, as a first draft from photos and notes. Specialists must confirm attribution, date and condition before publication.
Can AI value antiques?
AI can find and summarise comparable results. The specialist sets the estimate and reserve.
What auction software do UK houses use?
Many use the-saleroom, EasyLive or Invaluable for bidding, alongside their own auction management system.
Is AI cataloguing accurate?
It is a useful start but makes mistakes, especially with attribution. Always check against the object.
