Custom Fields

Custom Fields let you add your own product details — beyond the standard title, brand, size and condition — and have them filled in automatically and carried through to your listings. Think material, measurements, model, year, fit, or anything else that matters for the things you sell.

Setting up your fields

1. Go to Create Listings and open Settings (the gear icon).
2. Scroll to Custom Fields and choose Add custom field.
3. Give the field a name (e.g. Material) and pick its data type:

• Text — free text like "100% Cotton"
• Number — a plain number
• Measurement — a number with a unit you set (e.g. cm)
• Dropdown — a fixed list of choices you provide (e.g. Slim, Regular, Oversized)
• Yes/No — a simple toggle
• Year or Date

1. Set the options that fit the field:

• Let the AI fill this field automatically — the AI works out the value from your photos when it creates the listing. Turn this off for fields you only ever fill in yourself.
• Show this field on product forms — the field appears as an input when you edit a product on the web and in the mobile app. Turn this off for background-only fields the AI fills silently.
• Applies when (optional) — a short note in plain English telling the AI when the field is relevant, e.g. "only for clothing". Leave it blank and the AI decides on its own whether the field applies to each item.

Your fields are saved as soon as you add them.

How they get filled

When you create a listing with AI, the AI fills in each of your custom fields that it's allowed to — skipping any that don't apply to that particular item. You can always review and edit the values yourself on the product form, on the web or in the mobile app.

Where they show up

Custom fields are saved against each product and are included in your listings:

• On eBay, they're added as item specifics.
• On Shopify, they're saved as product metafields.
• On other channels, the detail is woven into your listing so it isn't lost.

Tips

• Use a Dropdown when you want consistent values (the AI picks from your list rather than inventing wording).
• Use Measurement with a unit for sizing details like length or width.
• Keep field names short and clear — they're shown to you on the form and, where supported, on the marketplace.
