AuctionWriter is a standalone AI cataloging tool for auctioneers, made by Webflare LLC, a web design agency in York, Pennsylvania, and launched in late 2024. In its own words it is “the end-to-end cataloging platform built for auctioneers: snap photos in the field, let AI draft titles and descriptions, review everything in a spreadsheet view, and export straight to 18+ auction platforms.” You photograph lots on your phone, the AI drafts a title, description, estimate and category, you tidy the result in a spreadsheet view, and you download a file for the platform that runs your sale.
That last step is the reason this guide exists. A cataloging tool solves the blank page. It does not solve the round trip: photograph the lot in one system, export a CSV and a zip of renamed images, import both into the auction platform, check that every image landed on the right lot, and do it again a thousand times before the sale. The auction houses we talk to are not asking whether AI can write a lot description. They are asking where the writing should happen.
This guide covers the alternatives to a standalone cataloging tool, and it judges them on that question. We build one of them, so read the Circuit section with that in mind. Everything about AuctionWriter below comes from its own site and app listing; sources are at the end.
What AuctionWriter Does
To be fair to the tool, it does more than write a description. From its site and App Store listing:
- Inputs. Photos from the phone camera or bulk folder upload, up to 30 images per lot; barcode scanning for UPC, EAN and ISBN; typed details such as weight and dimensions; and an optional CSV whose rows are matched to lots by lot number. Native iPhone, iPad and Android apps with an offline mode, and the AI reads lot numbers from tag photos.
- Outputs. Titles, descriptions, estimates and a category, with background removal on images. It supports 48 languages and 18 currencies.
- Where the output goes. A one-click download in the format of your listing platform. AuctionWriter names Auction Flex and AuctionFlex 360, LiveAuctioneers, Wavebid, BidSpirit, Proxibid, Auctioneer Software, BidWrangler, EstateSales.NET, Auction Techs, APro.bid, iCollector, Invaluable, AuctionWorx and Maxanet, plus universal formats. Its own walkthrough for AuctionFlex describes the export as a CSV plus a zip of renamed JPEGs that you then import.
- Price. Free for 50 lots with two users. Paid plans are priced by monthly lot quota: Standard at $99 per month for 1,000 lots and five users, rising through Business tiers to Enterprise IV at $1,689 per month for 31,000 lots and 50 users, with custom quotes above that. No long-term contract.
- Who it is for. Auctioneers running estates, liquidations, antiques, collectibles, industrial, farm and luxury sales.
Its own blog is candid that the AI can miscount small items, misjudge weight, struggle with authenticity and age, and miss rare markings, and that “AI is a starting point, but your expertise ensures the final catalog is error-free.” That is the right disclaimer and it applies to every AI cataloging product, including ours.
Why Auction Houses Look for an AuctionWriter Alternative
The complaints we hear about standalone cataloging tools are rarely about the prose. They are about everything around it.
The lot lives in two places. AuctionWriter holds the photos, the draft and the spreadsheet. The auction platform holds the lot record with its consignor, reserve, bidding and invoice. A file export connects them once, at import time. After that, a correction made in one system has to be repeated in the other.
Images make the trip twice. The photographs are uploaded to the cataloging tool, exported as a renamed zip, and imported again into the auction platform. That is fine for forty lots and a chore for four thousand.
House style is not stated. A sale reads well when every lot follows the same order of facts and the same terminology. AuctionWriter’s site does not say whether it learns an auction house’s previous catalogs; a tool that writes each description in isolation tends to drift, and the cataloger ends up editing for consistency rather than for accuracy.
Specialist fields are generic. The tool is positioned across estates, liquidations, farm equipment and luxury. A coin catalog needs grading service and grade, a stamp catalog needs catalog numbers and centering, and an art catalog needs medium, dimensions and provenance in a fixed order. Category templates for collectibles are not something AuctionWriter claims.
Nothing downstream knows the lot exists until import. Category alerts to collectors, the bidder CRM, invoicing and settlement all start from the lot record in the auction platform. A draft in a separate tool does not trigger any of it.
The quota meter. Pricing by lots per month suits a steady weekly estate auctioneer. A collectibles auction house that catalogs 3,000 lots in the month before a sale and 200 the month after pays for the peak.
Standalone Description Tool vs. AI Cataloging in the Platform
There are two ways to put AI to work on a catalog.
A standalone cataloging tool such as AuctionWriter is a drafting assistant. Its output is a file. Its strength is that it can sit next to almost any auction system, because it only needs to know that system’s import format. Its weakness is the same fact seen from the other side: it does not know anything about your sale, so every result has to be exported, imported and checked.
AI cataloging built into the auction platform writes into the lot record directly. On Circuit, a photograph and a line of the specialist’s notes become a full draft entry: title, description, condition notes, category and a suggested low and high estimate, in the auction house’s own style. The cataloger corrects and approves instead of writing from nothing. Because the draft is already a lot in the sale, it is also already in the bidder alerts, the CRM and the settlement pipeline. Nothing is re-keyed and nothing is lost between tools.
The practical difference shows up on the mid-value lots. A specialist will always write the highlight by hand. It is the four hundred lots in the middle of the sale, where a full write-up was never economic, that decide how long cataloging takes.
AuctionWriter Alternatives That Write Inside the Auction Platform
Circuit Auction AI
Circuit’s AI auction cataloging is part of the platform that runs the sale, not a separate product. What it does, from the product page:
- Specialists judge, AI drafts. A photo and a line of notes become a full draft entry. Grading, attribution, authenticity and the final estimate are always confirmed by a person before the lot is published.
- Your house style, every lot. Circuit learns how your auction house writes: the order of facts, the terms you use, how you hedge attribution. Descriptions read as if one careful cataloger wrote the whole sale.
- Estimates grounded in results. Suggested estimates draw on recent market results for comparable lots, and an automatic category assignment drives bidder alerts and catalog navigation.
- Category templates. Coins carry grading service and grade, stamps carry catalog numbers and centering, art carries medium, dimensions and provenance. The AI fills the fields your specialists expect.
- Bulk image matching. Upload hundreds of photographs at once and Circuit matches them to the right lots.
- Revision control and review. Every edit to a lot is kept, with who changed what and when. Catalogers review AI drafts in a queue, and nothing is published without a person signing it off.
- One catalog, 40+ languages. Translations are generated inside the platform from the same lot record.
- No copy and paste. Circuit writes straight into the lot record, with images, fields and estimates attached. A catalogued lot is already in the timed or live sale, the CRM alerts and the settlement pipeline.
Circuit’s cataloging is built for collectibles: coins, stamps, fine art, antiques, watches and jewelry, rare books, sports memorabilia, trading cards and similar fields. It is a fit for an auction house that wants the description, the estimate and the sale in one system. It is not a fit for a house that wants to keep its current platform and only add a writing tool. For the longer view of what AI changes in catalog production, see how AI is changing auction catalog creation.
Pricing: AI catalog creation is an add-on to the Standard Plan at $250 per month, and is included in Enterprise quotes. See pricing.
Bidsquare AI Auto Cataloging
Bidsquare added AI cataloging to its Bidsquare Cloud white label platform in January 2025. From uploaded images it generates an item title, low and high estimates, a description, condition and categories, and the result lands in Bidsquare’s Vault inventory system rather than in a file. It is only available to auction houses running on Bidsquare Cloud, which is priced on request. See our Circuit vs Bidsquare Cloud comparison for the rest of that platform.
LotUp by Bidlogix
LotUp is the AI cataloging add-on from the makers of BidJS. It is sold separately at £29, £59 or £99 per month and pushes finished lots into BidJS with one click, so for a BidJS auction house it removes the export step. It does not help an auction house on any other platform. See Circuit vs BidJS.
Keeping AuctionWriter
If your auction platform is fixed, and especially if it is one of the fifteen AuctionWriter exports to, the tool is a reasonable way to add AI drafting without changing anything else. The free tier of 50 lots is enough to test the output quality on your own material before paying.
What to Check Before You Choose
Whether you keep a standalone tool or move the writing into the platform, these are the questions that separate a demo from a working catalog.
- Where does the text land? In a text box you copy from, or in the lot record with the images and estimate attached?
- Does it see the photographs? A description written from a photo and a note is a different product from one written from a note alone.
- Does it write the other fields? Title, condition, category and estimate, or only the description?
- Does it learn your house style? Ask for ten lots from your last sale and compare the voice.
- Who signs off? A review queue with revision history, or a final draft with no record of what changed?
- What happens after the description? Alerts, bidding, invoicing and settlement should start from the same record.
- What does it cost per sale, not per month? Count the hours of pasting and image handling, not only the subscription.

How to Move Descriptions Into the Platform
If you decide the writing should happen inside the auction system, the move is smaller than a platform migration because the descriptions are only text.
- Export your last three catalogs. They are the house-style sample the AI learns from.
- Pick one category template first. Start with the field that has the most lots per sale, usually coins, stamps or cards, and check the terminology on twenty drafts.
- Run the next sale with the review queue on. Catalogers approve every AI draft. Time the sale against the previous one.
- Retire the copy-and-paste step once the drafts are landing in the lot record with images and estimates attached.
Making the Decision
A standalone cataloging tool is the right answer when your auction platform is fixed and the only gap is the blank page. It is the wrong answer when the blank page was never the slow part, and the slow part is moving text, images, estimates and categories between systems for every lot in the sale.
If the second sounds like your cataloging room, look at an alternative that writes inside the platform, and bring ten lots from your next sale to the demo.
Frequently Asked Questions
What is AuctionWriter?
AuctionWriter is a standalone AI cataloging tool for auctioneers from Webflare LLC of York, Pennsylvania. It drafts titles, descriptions, estimates and categories from photos, barcodes and notes, lets you review them in a spreadsheet view, and exports a file for 18 or more auction platforms. It is free for 50 lots and then priced by monthly lot quota from $99 per month.
How much does AuctionWriter cost?
The free plan covers 50 lots with two users. Paid plans start at $99 per month for 1,000 lots and five users and rise in steps to $1,689 per month for 31,000 lots and 50 users, with custom quotes above that. There is no long-term contract.
Does AuctionWriter integrate with auction platforms?
By file export rather than a live connection. You download a CSV and zipped images formatted for the platform you use, then import them. AuctionWriter lists AuctionFlex, LiveAuctioneers, Wavebid, Proxibid, BidWrangler, EstateSales.NET, Invaluable, AuctionWorx and others.
What is the best alternative to AuctionWriter?
For an auction house that wants cataloging inside the system that runs the sale, an auction platform with built-in AI cataloging: Circuit for collectibles auction houses, Bidsquare Cloud for auction houses that want a marketplace feed, or LotUp for auction houses already on BidJS. For an auction house that wants to keep its current platform and only add drafting, AuctionWriter itself is a reasonable choice.
Does Circuit’s AI cataloging replace a description tool?
Yes. Circuit generates the title, description, condition notes, category and a suggested estimate from a photograph and a specialist’s notes, writes them into the lot record, and the specialist reviews and approves. There is no separate writing tool and no pasting between systems.
Will AI get the attribution or grading wrong?
The AI drafts; your specialist decides. Grading, attribution, authenticity and the final estimate are always confirmed by a person before the lot is published, and revision control keeps every edit.
Can I use Circuit’s AI cataloging without moving my auctions to Circuit?
No. It is part of the Circuit Auction platform, so a lot catalogued with AI goes straight into your timed or live sale and its results feed invoicing, settlement and the CRM.
How much does AI cataloging cost on Circuit?
AI catalog creation is a $250 per month add-on on the Standard Plan and is included in Enterprise quotes. Standard is $250 per month with an annual commitment plus 2% on winning online bids; Enterprise is a fixed price with no commission.
