The problem

eBay Seller Hub was built for the first-party one-at-a-time-listing era. The reseller workflow has moved on.

eBay Seller Hub 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 eBay Seller Hub 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 eBay Seller Hub 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.

Sellers hitting Seller Hub's listing-volume ceiling

Seller Hub works for casual sellers but caps out for anyone running real volume — no bulk upload, no AI generation, no keyboard review. HumCity is the high-volume layer on top of eBay. Your store, fees, policies, and search treatment all stay the same; only the listing flow speeds up.

Sellers who already have inventory ready to ship

If you have a back room full of inventory and you're losing the listing race to Seller Hub's one-at-a-time form, HumCity ingests the backlog in Pile Mode batches. The backlog clears in days instead of months.

Sellers needing fast bulk revisions on existing listings

Bulk-editing in Seller Hub is painful — you typically need to download a CSV, edit it offline, re-upload, and fix the errors. HumCity's bulk-edit handles thousands of listings in one selection: price drops, shipping updates, item-specific backfills.

Sellers running collectibles or specialty categories

Specialty categories (cards, coins, comics, LEGO) require careful item specifics that Seller Hub's generic form doesn't optimize for. HumCity's category-aware AI fills correctly the first time — slabs read accurately, sets recognized, varieties tagged.

How it works

From inventory to live listings in three steps.

01

Drop your photos

10, 100, 500 items — all in one batch via Pile Mode.

02

AI builds every listing

Title, item specifics, category, condition, pricing — generated in parallel.

03

Bulk publish to eBay

Approve in batches with keyboard shortcuts. Listings appear in Seller Hub normally.

FAQ

Common questions

Will my listings still appear in Seller Hub?
Yes — HumCity uses eBay's official API. Listings appear normally in Seller Hub and on eBay search, count toward your eBay metrics, and are managed the same as Seller Hub-created listings from eBay's perspective.
Can I revise listings in HumCity that I created in Seller Hub?
Yes — pull existing listings into HumCity for fast bulk revision. Title, price, item specifics, shipping, and any other field is editable across selections of any size.
Is HumCity an official eBay product?
HumCity is an independent eBay API partner authorized to use the Trading and Inventory APIs. It is not an official eBay product but is built on the official API with full eBay endorsement of the integration pattern.
Does using HumCity affect my eBay seller standing?
No. Listings from HumCity look identical to Seller Hub listings from eBay's perspective. Top Rated status, Best Match eligibility, and all other seller standing inputs work the same way.
Can I use HumCity and Seller Hub side by side?
Yes. Most sellers run both — HumCity for new listing creation and bulk revisions, Seller Hub for the day-to-day order management and store-level views. The two tools complement rather than replace each other.
What about the eBay Seller Hub mobile app?
The eBay mobile app is still useful for order management and customer messages. HumCity is web-native and works in mobile browsers; a HumCity native mobile app is on the roadmap.
Will I be charged any extra eBay fees?
No. eBay insertion and final-value fees are the same regardless of how the listing was created. HumCity's subscription is separate from eBay's fees.
Does it work with my existing eBay business policies?
Yes — on store connection, HumCity syncs your existing shipping, payment, and return policies and applies them to new listings by default. You can override per-listing or per-batch.
What if eBay changes a category's item specifics?
HumCity syncs the eBay category and item-specifics schema on a regular cadence. Schema changes propagate to the generator automatically — you don't need to do anything to stay current with eBay's evolving requirements.
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.
Is my eBay account and inventory data secure?
Yes. HumCity authenticates via official eBay OAuth — we never see or store your eBay password. Photos and listing data are encrypted in transit and at rest. We do not sell or share your inventory data with any third party.
