The problem

CrazyLister was built for the drag-and-drop-template era. The reseller workflow has moved on.

CrazyLister 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 CrazyLister 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 CrazyLister 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.

CrazyLister users facing template fatigue

CrazyLister's drag-and-drop template builder was beautiful — for a workflow that's becoming obsolete. HumCity skips templates entirely. Each listing gets a unique, AI-generated description in eBay's modern responsive format. Less maintenance, better mobile rendering, better search performance.

Sellers whose templates don't render well on mobile

Many CrazyLister templates were built for desktop eBay viewing and render poorly on mobile. eBay's modern responsive description format works correctly on every device. The migration to HumCity is also a migration to mobile-friendly descriptions.

Sellers running heavy listing volume

Templates were a productivity tool when listing was form-based. AI generation is a productivity tool when listing is photo-based. For high-volume sellers, the AI approach is dramatically faster — the template choice doesn't matter when the cataloging work itself collapses to seconds.

Sellers wanting category-specific item specifics

CrazyLister focuses on description design; item specifics are still manual. HumCity fills category-specific item specifics automatically from the photo extraction, which is often the larger time win compared to description templating.

How it works

From inventory to live listings in three steps.

01

Upload your photos

No template design step required. AI generates eBay-native descriptions per listing.

02

AI generates the listing

Title, item specifics, category, condition, pricing — automatic.

03

Publish to eBay

Bulk approve and ship via the official API.

FAQ

Common questions

Why switch from CrazyLister?
CrazyLister is a beautiful template designer for a workflow that's becoming obsolete. HumCity skips templates entirely and generates the listing from photos. The migration is from "design once, type forever" to "shoot once, approve forever."
Does HumCity support custom listing design?
HumCity uses eBay's modern responsive description format, which renders correctly on every device. Custom HTML templates are intentionally not part of the workflow — eBay's mobile listing rendering rewards the responsive format and penalizes legacy templates in mobile search visibility.
What about my existing CrazyLister templates?
Templates don't migrate because HumCity doesn't use templates. The migration is a workflow change: instead of designing once and applying everywhere, you let the AI generate per-listing descriptions. Most CrazyLister users find the trade-off favorable because template maintenance disappears.
Will my eBay listings look worse without templates?
Mobile rendering will likely look better (responsive format vs. fixed-width templates). Desktop rendering is comparable for most product categories. The bigger gain is that descriptions are now per-listing-accurate rather than stamped from a generic template.
Can I add my brand information to every listing?
Yes. Standard footer text (brand statement, shipping notes, return policy summary) can be applied as a description suffix across all listings — equivalent to a brand template footer.
Does HumCity handle eBay Stores customization?
eBay Store branding (header, footer, custom pages) is configured in eBay Seller Hub itself, not in HumCity. The store experience remains under your control; HumCity affects only the per-listing flow.
Is the AI description better than my template?
For mobile rendering and item-specifics accuracy, yes. For brand-customized desktop appearance, your template may be more visually distinctive. The trade-off favors AI for most sellers because mobile traffic is the majority of eBay views today.
What about CrazyLister's mobile-responsive templates?
CrazyLister's responsive templates are good, but per-listing AI-generated descriptions outperform shared templates on both accuracy and search relevance. The structural difference is that the AI tailors the description to the actual item rather than to the template's structure.
Does HumCity have a template gallery?
No — and that's intentional. Templates create the maintenance burden HumCity is trying to eliminate. The AI generates the description; you customize standard elements (footer, signatures, policy clauses) once at the account level.
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.
