Winning attributes of Amazon best sellers, for your listing, shop or product, and a check.
Scored across 18 tools
The Scan-vs-Match split is well explained, but several tools shadow each other: wintraits_atributos_ganadores vs wintraits_scan_perfil (winning attributes split only by category tier), wintraits_chequeo_rapido vs wintraits_diagnosticar_producto (the former explicitly says Match categories 'also accept it, but diagnosticar gives more'), and wintraits_chequeo_asin vs wintraits_chequeo_rapido. wintraits_hallazgos vs wintraits_evidencia and wintraits_evaluar_concepto vs wintraits_diagnosticar_producto also overlap. Descriptions usually resolve the choice, but an agent must read carefully to avoid misselection.
All 18 tools share the wintraits_ prefix, snake_case, and Spanish domain vocabulary, which is very predictable. The only inconsistency is grammatical form: some are verb_noun (buscar_categoria, diagnosticar_producto, seguir_ficha) while others are bare noun phrases (atributos_ganadores, scan_perfil, hallazgos, opinion, ranking). Readable and coherent overall, just not a strict verb_noun pattern.
18 tools is at the heavy end but each covers a distinct output (attributes, profile, diagnosis, comparison, ASIN check, category panorama, success ratio, ranking, history, findings, evidence, options, follow, feedback). The domain genuinely spans several analysis modes, so the count is defensible rather than padded, though a couple of pairs could be merged.
The surface covers the full workflow: category discovery, winning-attribute lookup, listing diagnosis, pre-manufacture concept evaluation, A/B comparison, market sizing, ranking, history, evidence, plus follow-up and feedback. Minor gaps: no unfollow tool (deferred to the user's account), no way to list or manage followed listings, and no direct competitor/price lookup beyond category bands.
Which attributes do winning products have? What should my product or listing include? (¿Qué atributos tienen los productos que triunfan? ¿Qué debe llevar mi producto o mi ficha?)
Match categories (see wintraits_categorias_disponibles, disponibles; e.g. serums on Amazon Spain): attributes
and 2-3 attribute combinations that set the winning launches of a category apart. For Scan-only categories use
wintraits_scan_perfil. Useful beyond Amazon too: to design a product, brief a manufacturer or write the page of
an own shop or another marketplace (measured on Amazon: a reference, not proof elsewhere).
Each row has the lift (how many times more frequent among winners), the lift when checked against products
launched later, the products behind it and the share of products with that attribute that end up winning.
tramos explains what "bajo" (low), "medio" (medium) and "alto" (high) mean for numeric variables. On the free
plan you see the attribute with the most effect and how the strongest combination starts
(combinacion_mas_fuerte); bloqueado says how many more the full list has and acceso which view was used.
Args: categoria: subcategory (see wintraits_categorias_disponibles; e.g. "serums"). pais: country code (see wintraits_categorias_disponibles; e.g. "ES"). max_resultados: rows per list (1-50). lang: "es" (default) or "en" (attribute names in English).
Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027).
Inputs: lang, pais, categoria, max_resultados.
Find the category code from words: "air fryer", "juegos de mesa", "vitamin C serum", "puzzles". (Busca el código de una categoría a partir de palabras, en español o en inglés.)
Call it before any other tool when you do not know the exact categoria: never guess codes. Returns up to 15
matches, best first, with categoria and pais (pass them as they come to the other tools), the name, nivel
("match": every tool; "scan": wintraits_scan_perfil, wintraits_ranking, wintraits_chequeo_rapido,
wintraits_chequeo_asin) and the link. With no match, use wintraits_categorias_disponibles.
Args: texto: what the user sells or wants to sell, in Spanish or English. pais: preferred country code ("ES", "FR", "DE", "IT"); matches in that country come first. lang: "es" (default) or "en".
Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027).
Inputs: texto (required), lang, pais.
Categories and countries covered by Wintraits (valid values of categoria and pais). Call it first.
disponibles: Match categories (nivel "match", with estado_examen): every Match tool works. solo_scan: Scan
categories (snapshot of today's best sellers, with fecha_datos): wintraits_scan_perfil (winning attributes),
wintraits_scan_historia, wintraits_chequeo_rapido and wintraits_chequeo_asin. New Scan categories every week.
The data comes from Amazon, but the attributes also help outside Amazon (own shop, other marketplaces, product
design, packaging).
Args: lang: "es" (default) or "en".
Free and unlimited during the beta (until 2027-01-31). Gratis y sin límite durante la beta (hasta el 31-ene-2027).
Inputs: lang.
Quick check of an Amazon listing by its ASIN or product link: we read the public listing, detect its Scan category and return the same as wintraits_chequeo_rapido. (Chequeo rápido de una ficha de Amazon por su ASIN o enlace.)
ficha_leida gives the ASIN, the detected category and where its price sits against the middle half of best
sellers (por_debajo, dentro, por_encima). The listing's text and price are not returned. If the product is
not in a category with Scan published, it returns an error with the available categories: then use
wintraits_chequeo_rapido with the pasted listing and the closest category.
Args:
asin_o_enlace: ASIN (10 characters, e.g. "B0XXXXXXXX") or Amazon product link (its country wins over pais).
pais: country code when only the ASIN is given (default "ES").
lang: "es" (default) or "en".

Inputs: asin_o_enlace (required), lang, pais.
Does my listing have what today's best sellers have? Quick check of a listing, a technical sheet or a draft. (¿Tiene mi ficha lo que tienen hoy los más vendidos de mi categoría?)
Every Scan category (solo_scan in wintraits_categorias_disponibles; use wintraits_buscar_categoria to find the
code): a snapshot of today's best sellers against the rest, not a prediction. indice_scan is the Wintraits Scan Index (0-100: how much of the
best sellers' distinguishing traits the listing has, weighting the top-ranked sellers more; 100 = the most
complete best-seller listing today; puntos is the raw 0-100 score before that scaling; only the traits readable
from the listing count), with the middle
half of best sellers and of the rest (out of sample); null if fewer than 3 traits can be read. zona says where it
falls: "mas_vendidos" (best sellers' zone), "entre" (in between), "resto" (the rest's zone) or "por_encima" (well
above the best sellers: it mentions more traits than usual, and adding more does not bring it closer to them; never
present it as better than the best sellers). Always name it
"Wintraits Scan Index" with its best sellers' band (texto); give the user its frase and zona_frase; metodo links to how it is computed. cifras gives, for images, bullets, title and description length and price, the listing's value
(tu_ficha) next to the median and middle half of best sellers and of the rest. Each trait says how often it appears
among best sellers and the rest, and lo_tiene = true/false if it can be read from the listing, null if the user
must check it. te_faltan lists the listing traits more frequent among best sellers that the listing lacks.
indice_scan.partes splits the index into producto and presentacion (null with a motivo when it cannot be
computed, never 0). The listing does not need to be on Amazon: a draft or the page of another shop works too.
Match categories (disponibles) also accept it, but wintraits_diagnosticar_producto gives more.
Args:
titulo: listing title.
categoria: Scan category id (e.g. "hidratantes"; see wintraits_categorias_disponibles).
pais: country code (e.g. "ES").
vinetas: bullet points of the listing.
descripcion: listing description.
num_imagenes: number of images, if known.
video: whether the listing has a video, if known.
precio_eur: selling price in euros, if known.
ficha_tecnica: technical sheet text (no online listing), used when titulo is empty: only the product part
of the index is computed; partes.presentacion comes with valor null and motivo "sin_ficha_de_tienda".
lang: "es" (default) or "en".

Inputs: lang, pais, video, titulo, +6 more.
Which version of my listing is better? Compares two listings of the same category. (¿Qué versión de mi ficha es mejor?)
Returns the diagnosis of each one (a and b), the difference in Wintraits Match Index points, a conclusion and
the attributes read that differ between them. On the free plan both are shown in the free view.
Args: ficha_a: {"titulo", "precio_eur", "num_imagenes", "vinetas", "descripcion", "volumen_ml"} of the first. ficha_b: the same for the second (e.g. another version of the same listing). categoria: subcategory (see wintraits_categorias_disponibles; e.g. "serums"). pais: country code (see wintraits_categorias_disponibles; e.g. "ES"). lang: "es" (default) or "en" (attribute names in English).

Why isn't my product selling? What should I change in my listing? (¿Por qué no vende mi producto? ¿Qué cambio en mi ficha?)
Match categories (disponibles). Diagnoses a product listing (Amazon, an own shop, another marketplace or a
draft): Wintraits Match Index (similarity to winners, 0-100, not a sales probability; always
call it by that name, indice_match.texto), the changes that
raise it most and the winning combinations within reach (missing one or two elements). On the free plan you
see the first changes; bloqueado says how many more the full report has and acceso which view was used.
Optional atributos: if you (the AI) read the listing yourself, call wintraits_opciones_concepto first and
follow its instrucciones_extraccion: use only what the listing says (never deduce), exactly the keys of
atributos and, for lista/categoria, only their valores; omit anything the listing does not say (we read it
from the text). Invalid keys or values return an error with the valid options.
Args: titulo: listing title. precio_eur: selling price in euros. num_imagenes: number of images in the listing. vinetas: bullet points of the listing. descripcion: listing description. volumen_ml: volume in ml, if not in the text. atributos: optional {key: value} read from the listing (keys and values from wintraits_opciones_concepto). categoria: subcategory (see wintraits_categorias_disponibles; e.g. "serums"). pais: country code (see wintraits_categorias_disponibles; e.g. "ES"). lang: "es" (default) or "en" (attribute names in English).

each listing has (rasgos), with the best sellers' middle half (franja_mas_vendidos). Brand, title and Amazon
link only for listings with an index of 60 or more. Use it as examples of how the best sellers present the
winning traits; the number is not comparable across categories and is not a sales probability.

that has it (pct_mas_vendidos, pct_resto), its tipo (producto = what the product is or offers, the part
that also works outside Amazon; presentacion = how it is told online; tienda = depends on who sells), whether it
counts in the Wintraits Scan Index, the medians of images, bullets, text length and price (cifras), the
