Yes - AI cataloging works for Proxibid sellers, and the reason it works cleanly is that Proxibid is one of the platforms Gavelist exports a ready-made file for. The catalog is generated once, then handed to Proxibid in its own import-ready format, so there is no fighting a mismatched spreadsheet at upload time.
How it works
AI cataloging turns lot photos into a title, description, category, and value estimate, then formats that output for the destination platform. For a Proxibid seller, the workflow is: photograph the staged lots, run the AI description pass, and export the Proxibid-ready file. Gavelist's description pass runs at about 1,000 lots in 10 minutes, which is the part that removes the cataloging bottleneck on a large consignment. The reason this matters is the labor it replaces: according to Estimint's cataloging analysis, manual cataloging of a 200-lot sale takes 46-64 hours - roughly 14-19 minutes per lot. According to AIM (2025), manual cataloging runs 15-25 lots per hour at $14-$28/hour.
What to look for in an AI cataloging tool for Proxibid
Three things separate a tool that helps from one that just generates text:
- Multi-photo analysis. Single-photo tools guess from one angle. Because Proxibid lots sell as-is on their photos, multi-angle input matters - according to AuctionNinja's photography best practices guide, auction lots should have at least 3 photos, one main plus two from varying angles, scaled by value.
- Values and comps grounded in real sold prices. A value estimate is only useful if it reflects what items actually sell for. Gavelist assigns each lot a value tier and a low-to-high estimate grounded in market comps from real sold and completed listings, not asking prices.
- Platform independence. Your catalog should not be trapped in one marketplace. Gavelist exports ready-made files for HiBid, LiveAuctioneers, Proxibid, and BidWrangler, plus a universal CSV/XLS formatted for import by AuctionZip, AuctionMethod, Wavebid, AuctionFlex 360, and any other spreadsheet-import platform - so a Proxibid catalog is not locked to Proxibid.
The honest limit
AI cataloging is strong on volume and consistency and weaker on judgment calls. According to Mearto, AI "can recognize items and locate comparable online items" but still lacks the connoisseurship to judge authenticity, condition, and provenance the way a human appraiser does. For high-value Proxibid lots, treat the AI estimate as a first pass and review it - Gavelist supports this directly by letting the auctioneer review the ranked pool of candidate comps and choose which ones appear on a lot.
A growing market
The tailwind is real: according to Technavio (2025), the global online auction market is projected to grow by USD 3.98 billion from 2025 to 2029, at a CAGR of approximately 14%, and Proxibid sellers scaling their lot counts are part of that growth.

Frequently asked questions
Does AI cataloging actually work with Proxibid? Yes. Proxibid is a supported export target, so an AI-generated catalog can be exported in Proxibid's import-ready format without manual reformatting.
Do I still need to review AI-cataloged lots for Proxibid? For routine and box lots, minimally. For high-value lots, yes - review the estimate and comps, since AI lacks the connoisseurship for authenticity and provenance calls.
Can I use the same AI catalog on Proxibid and other platforms? Yes. The catalog is platform-neutral - export a ready-made Proxibid file, or a universal CSV/XLS for other platforms - without re-cataloging.
