Which AI model powers the listing generator?

GPT-4o, prompted and grounded on platform-specific structures we've validated against thousands of high-converting listings. We tune the prompt regularly as Vinted's discover feed and eBay's Cassini search rankings evolve.

Can I edit the output?

Always. Every description is shown in an editable text area before you save. Most resellers tweak one or two sentences — but the structure, keyword density, and tone come ready to go.

Does it work for sneakers, handbags, electronics?

Clothing is the primary use case and where the model is best tuned. Sneakers, handbags, and accessories work well too. For electronics and Pokémon cards, we recommend pairing with the dedicated Pokémon scanner or eBay sold-comps lookup for accurate spec details.

Is there a per-listing AI cost?

No. AI listings are unlimited on every Pro plan. We don't meter or upcharge per generation.

How does it handle multiple sizes or variants?

Generate the description, then duplicate the inventory item with a different size — the description stays the same and you don't pay any extra AI cost. Variants are a planned native feature.

Why generic AI tools don't work for reselling

Ask ChatGPT to write you an eBay listing and you'll get something polite, generic, and ranked nowhere. The reason: the prompt knows nothing about how eBay search actually works, what condition grades mean to UK buyers, what hashtags Depop's algorithm rewards, or how Vinted users read transparency vs. fluff.

ResellIQ's listing generator is purpose-built for reselling. The model is grounded on the actual structure of high-converting listings on each platform — keyword density patterns from top-ranking eBay listings, the casual-but-honest voice that wins on Vinted, the under-55-word punch that makes Depop scroll-stoppers.

And critically: it generates four versions at once. One item in, four channel-perfect descriptions out. No more rewriting the same listing five different ways for five different audiences.

What you get per item, in one click

eBay description — SEO-keyword-rich, spec-heavy

Built around how eBay's Cassini search ranks listings: brand and model in the first 80 characters, key specs as bullet points, condition described in eBay's vocabulary, and category-relevant keywords woven naturally throughout.

Vinted description — conversational, transparent

Vinted buyers reward honesty. The Vinted version reads like a friend describing their wardrobe — relaxed tone, clear sizing, honest condition notes, and the specific hashtag patterns Vinted's discover feed picks up.

Depop description — under 55 words, scroll-stopping

Depop is a Gen-Z aesthetic-first platform. The Depop output is short, punchy, vibe-led, and uses the platform's actual hashtag conventions (#y2k, #vintage, #streetwear) rather than generic SEO keywords.

Poshmark description — aspirational, styling-led

Poshmark sells a lifestyle, not a garment. The Poshmark version leans into styling cues — what you'd wear it with, the occasion it suits, the silhouette and feel — without sacrificing detail on size and condition.

Image-aware — works from a photo

Pair the generator with the AI scanner and you can go from a single phone photo to four full descriptions in under 15 seconds. The scanner identifies brand, style, condition and material; the generator turns that into ready-to-paste copy.
