Why the Mercari listing AI writes inside Mercari's own limits
Mercari cuts off what does not fit and buries what it cannot place. A listing written to the form's own rules is the one that survives both.

One example, a pair of used headphones. Every value here is one the Mercari form accepts, and the one choice it cannot make for you is marked as yours.
The category comes first, down to the leaf
The item is placed on Mercari's own category list before a word is written, and when a subcategory clearly fits, you get the exact leaf instead of guessing the drill down.
A condition from Mercari's own five
New, Like new, Good, Fair or Poor, judged from your close ups. Wear stays honest: flaws go into the description one per line, not behind a kinder tier.
Written to fit the box
Mercari cuts descriptions off at 1000 characters. The body is budgeted under that from the start, so nothing you paste gets clipped mid sentence.
All 3 hashtags, where they work
Mercari has no hashtag field, so the tags are written into the end of the description, the only place they count as search entries.
Every field the Mercari listing AI fills in
A Mercari listing is a short form with hard edges. Here is what comes back already filled in, in the order the form asks for it.
- Title
- Up to 80 characters, led by brand and model, then the traits buyers type into Mercari search.
- Description
- Plain text budgeted under the 1000 character cap: flaws one per line, measurements, what is included.
- Category
- Picked from Mercari's own list, with the subcategory leaf filled in when one clearly fits.
- Condition
- One of Mercari's five tiers, judged from your close ups rather than defaulting to the kindest one.
- Size and color
- The label size for apparel and shoes, and the main colour, for the filters buyers narrow by.
- Hashtags
- All 3 slots used, written into the end of the description, which is where Mercari reads them.
- Suggested price
- A starting range in whole dollars, inside the range Mercari's price field accepts.
- Shipping
- Left to you on purpose: who pays and the package weight are choices Mercari asks when you post.
- Photos
- Up to 12 at once, read in one pass, so the tag, the flaws and the box all end up in the text.
These are Mercari's own fields, not a relabeled template. Nothing claims authenticity the photos cannot prove, or invents a pet free home.
The Mercari listing AI cleans up your cover photo too
Mercari search is a grid of square photo tiles, and yours competes with every listing that matched the same words.
Background removed
Swap the kitchen table for plain white, light grey, or a transparent PNG you can drop onto any backdrop.
Cropped square
Rotate a crooked shot level and crop it square, the shape Mercari's search grid shows first.
Brightness and colour
A gentle touch up for dim indoor shots, so the colour a buyer taps on is the colour that ships.
Your item is never repainted. The background is cut away, not regenerated, so nothing about the item is invented. On secondhand goods the exact wear is what is being sold, and it leaves exactly as photographed.
Mercari listing AI questions, answered
What sellers ask before they start: how the category and condition get chosen, where the hashtags go, and what a listing costs to generate.
No. Mercari publishes no listing API for individual sellers, so any tool that posts for you is automating your account. Holgo stays out of your account entirely: you generate the listing here, then paste it into the Mercari app or site yourself. Your login stays yours.
A tool that reads photos of your item and writes the listing for you: title, description, category, condition, hashtags and a price. Holgo's Mercari listing AI writes the Mercari shaped version of all of that, so what comes back drops into the listing form rather than needing to be trimmed and reworked first.
From Mercari's own list. The item is matched to a category from the real set, and when a subcategory clearly fits, the leaf is filled in too, so you are not guessing your way down the picker. A leaf that does not belong to the chosen category is dropped rather than shipped.
From Mercari's own five tiers: New, Like new, Good, Fair or Poor. The judgement comes from your close ups, and the description backs it up by listing flaws one per line, which is what keeps a buyer from disputing the tier after it arrives.
Into the end of the description, because Mercari has no hashtag field and that is the only place tags work. All 3 slots are used, since an empty one is a search entry given away, and the description body is budgeted so the tag line never gets cut off by the form.
Every field, always. Title, description, category, condition, hashtags and the price are yours to change before you paste anything. It is a first draft written in seconds, not a decision made on your behalf.
The title is kept inside the 80 character limit and spends its budget on searchable words, brand and model first. The description is budgeted under Mercari's 1000 character cap with the hashtag line included, so nothing you paste gets clipped mid sentence.
That is most of what sells on Mercari, and most of what this was built for. Wear is read from your close ups and described flaw by flaw, measurements are taken from the photos where they are visible, and the condition tier follows the evidence rather than the asking price.
That part stays yours, on purpose. Who pays for shipping and what the package weighs are choices Mercari asks when you post, and they depend on your box and your scale, not on the photos. The copy content marks it clearly so nothing is silently guessed for you.
