The Crosslist alternative built around AI

Crosslist asks you to fill out the listing once. HumCity generates the listing from the photo.

The problem

Crosslist was built for the manual-master-listing era. The reseller workflow has moved on.

Crosslist solved a real problem in its day — but the problem has changed. The reseller workflow is no longer "build a template, copy it for every listing, ship it to eBay." The modern workflow is photo-first: photograph the inventory, let AI generate the listing, review, publish. Every step that involved a human typing repetitive cataloging data has either been removed or moved to a one-keystroke approval action.

The cost of staying on Crosslist isn't just the subscription. It's the compounding time you spend on data entry that doesn't have to exist. For a seller doing 30 listings per week, ten minutes per listing means five hours of weekly typing — 260 hours per year — that AI can do in seconds.

HumCity is what Crosslist would be if it were rebuilt from scratch in 2026 with the current state of vision-language AI. Photo-first input, AI-generated listings, keyboard-first review, bulk publish via the official eBay API. The output looks the same to eBay; the workflow to get there is ten times faster.

What you get

Capabilities built for this exact workflow.

  • AI listing generation from photos

    Drop product photos and the AI generates the title, item specifics, category, condition, description, and pricing. The cataloging work that took 6–10 minutes per listing collapses to seconds. The seller's job becomes review and approval, not typing.

  • Pile Mode™ bulk upload (10–500 items)

    Bulk listing means dropping a pile of photos, not building a CSV. Pile Mode supports up to 500 photos per upload with parallel AI inference. Multi-photo items are auto-grouped, duplicates are flagged, and the review queue is built for keyboard speed.

  • Direct eBay API integration

    Listings publish via the official eBay Trading and Inventory APIs. From eBay's perspective, listings look identical to Seller Hub manual creation — same search treatment, same Best Match eligibility, same Seller Hub visibility. Your business policies sync automatically.

  • Modern UI built for keyboard-first volume

    The review queue is designed for sellers who think in stacks. Arrow keys to navigate, J/K to approve/edit, Cmd+Enter to publish. Dark mode, responsive layout, mobile-friendly. The kind of interface that respects sellers' time at 100+ listing volume.

  • Free for the first 50 listings per month

    Every account gets 50 free listings or revisions per month with no credit card required. Most sellers can fully evaluate the AI workflow, bulk upload, and review queue before deciding to upgrade. Paid plans start at $10/month for 500 listings and scale with volume.

  • Collectibles-aware AI (cards, slabs, coins, comics, LEGO)

    Specialty categories get specialty intelligence. The AI reads slab labels (PSA, BGS, CGC, SGC, NGC, PCGS), recognizes Pokémon sets, identifies LEGO set numbers, parses comic covers, and reads vinyl matrix codes. The category-specific item specifics fill correctly the first time.

Use cases

Built for the way real resellers work.

Closet and apparel resellers tired of typing the master listing

Crosslist's value prop is type the master listing once and crosspost — but you still type the master listing. HumCity removes the master-listing step. AI reads the brand, size, and condition from photos and ships listings to eBay (and other channels as they come online).

Collectibles dealers needing slab and set recognition

Crosslist treats all categories as generic. HumCity's collectibles AI reads slabs, recognizes sets, and tags variants. The category-specific intelligence is the structural advantage for collectibles dealers.

Bulk-first sellers wanting Pile Mode

Crosslist is one-master-listing-at-a-time. Pile Mode is 500-photos-at-once. For sellers running real volume, the bulk workflow is the structural shift.

Sellers who want AI to make the cataloging decisions

Crosslist users typically know exactly what they're listing and just want the crossposting automation. HumCity is for sellers who want the cataloging decisions automated too — what category, what specifics, what title, what comp.

How it works

From inventory to live listings in three steps.

01

Drop your photos

No manual data entry first. AI generates the listing from the image.

02

AI builds the listing

Every field generated automatically with category-appropriate specifics.

03

Publish to eBay

Direct API publish. Other marketplaces on the roadmap.

FAQ

Common questions

Why switch from Crosslist?
Crosslist crossposts manual listings to multiple marketplaces. HumCity removes the manual step — AI builds the listing from your photos and pushes to eBay. As multi-channel integrations ship, the cross-listing capability matches Crosslist's footprint while keeping the AI workflow.
Which marketplaces does HumCity support?
eBay is live today via the official API. Mercari, Whatnot (beta), Shopify (beta), and Poshmark are on the roadmap. The inventory hub is unified across channels.
Does HumCity replace my entire Crosslist workflow today?
For eBay-focused sellers, yes — fully. For sellers running multi-channel crosslisting where Crosslist's coverage matters, HumCity covers eBay today and the other marketplaces are coming. The AI workflow is the differentiator even before the multi-channel parity ships.
How does HumCity's bulk upload compare to Crosslist?
Pile Mode supports 500 photos per batch with parallel AI generation. Crosslist is fundamentally one-master-listing-at-a-time. The bulk approach is the structural difference for high-volume sellers.
Can I migrate my Crosslist inventory?
Yes via CSV export from Crosslist and CSV import to HumCity. Going forward, the photo-first workflow means the historical CSV import is a one-time step.
Does it have Crosslist's delisting/relisting automation?
Bulk listing management (relist, end-and-relist, schedule launches) is in HumCity today. Cross-marketplace delisting on sale (when an item sells on Mercari, end the eBay listing) is part of the multi-channel inventory sync that ships with each new integration.
Is HumCity cheaper than Crosslist?
Pricing is comparable on the entry tiers — HumCity's free tier covers 50 listings/month vs. Crosslist's trial. Paid plans scale on listing volume rather than per-crosspost, which is generally cheaper at high volume.
Does HumCity have a browser extension?
No — and that's intentional. The AI workflow doesn't require an extension because we don't pull data from existing listings on other sites; we generate from product photos directly.
Is there a free tier?
Yes. Every account gets 50 free listings or revisions per month with no credit card required. Most resellers can fully evaluate the AI workflow, image recognition, and bulk upload before deciding to upgrade. Paid plans start at $10/month for 500 listings and scale with volume.
Does HumCity use the official eBay API?
Yes. HumCity is an authorized eBay API partner and uses the official Trading and Inventory APIs. Every listing published from HumCity appears in eBay Seller Hub normally, counts toward your eBay reputation, and respects your existing business policies for shipping, returns, and payments.
