Check the gender of a name

Gender Guesser uses artificial intelligence specialized in the morphology of names to determine with great precision whether a name is masculine, feminine or unisex.

Gender guesser’s name checking tool can help you check if a name is more likely to be male, female or unisex. We offer many possibilities of treatments for gender name determination: you can provide a full name or a first name and even add a local context to the request.

Guess gender from a name

Guess the gender from a first name and an optional last name or an undivided full name. Using the last name, our tool can derive geographical context that aids in gender identification. The feature for split full names "First & last name" will be slightly more accurate than the feature for full names "Full name".

First name, given name, nickname.

Last name, surname to improve accuracy.

What is the gender of a name?

Gender represents a societal concept encompassing a range of traits associated with both femininity and masculinity. In various contexts, this can encompass aspects such as identity, societal roles, cultural influences, historical factors, political implications, and symbolic dimensions that contribute to the formation of gender identities. Many societies adhere to a binary gender classification system, distinguishing between two categories: males (boys/men) and females (girls/women).


In the realm of gender evaluation through a complete name or first name, it's essential to note that absolute certainty cannot be guaranteed. This is due to the fact that certain first names are frequently adopted by individuals of both genders, though in varying proportions. As a result, we furnish an estimation of the accuracy probability pertaining to the identified gender. Incorporating a last name significantly enhances precision, as it affords a better context for understanding the usage of the first name within its cultural setting. When the identified gender probability falls within the 40% to 60% range, it indicates that the name can be construed as not specifically associated with a particular gender.

Estimation improved with local context

Determine the gender based on a given name and, if provided, a surname, or an complete full name, with increased precision thanks to the indication of a local context (country of residence, country of origin, etc.).

Why add a local context to estimate gender?

Indicating a local context or cultural context to a name can improve the precision of estimated gender because names often carry different gender associations in various regions and cultures. Here's why:

  • Cultural Variations: Names can have distinct gender associations in different cultures. For example, a name considered male in one culture might be considered female in another. Providing a local context allows the system to consider these variations.
  • Unisex Names: Some names are unisex, meaning they are used for both males and females. However, the frequency of use can vary by region. In some places, a unisex name may be predominantly used for one gender, while in another, it may be more evenly split.
  • Historical and Traditional Influences: Historical and traditional factors can also play a significant role in naming conventions. Names that were once exclusively male or female may have evolved to become unisex over time.
  • Local Popularity: The popularity of names can vary widely by region. A name that is extremely popular for one gender in one area may be relatively uncommon for that gender in another.

    By taking into account the local context or cultural context, the system can analyze the name in relation to its surroundings, historical influences, and contemporary trends, which enhances its ability to estimate the gender associated with that name more accurately.

Gender of Chinese names

Examines a Chinese first name and, if provided, a surname, or an unseparated Chinese full name, in both standard Mandarin Chinese and Latin alphabet (Pinyin), to determine the gender association with increased precision.

About the gender of a Chinese name in Pinyin or standard Mandarin

When dealing with a Chinese name expressed in standard Mandarin or Pinyin, gender classification is binary, categorized as either masculine or feminine. If the likelihood of the assigned gender falls within the range of 50% to 60%, the name can be considered as potentially gender-neutral or unisex.

  • Pinyin serves as the endorsed system for romanizing Standard Mandarin Chinese. It employs the Latin alphabet to represent Mandarin characters and is utilized in languages like English.
  • The official language of China is Standard Mandarin Chinese, which employs a logographic script known as Hanzi, more widely recognized as Chinese characters.

About the gender of a Japanese name romanized or in Kanji

When dealing with a Japanese name expressed in either kanji or Latin script, the gender is determined through an estimation process that adheres to a binary classification: masculine or feminine. Beyond being classified predominantly as masculine or feminine, a given name may also fall into the category of unisex or gender-neutral if the likelihood of the estimated gender hovers near 50%.

  • Romanization entails the process of converting or transcribing a distinct writing system into the Latin alphabet.
  • Kanji are the logographic characters that have been integrated into the Japanese writing system. They constitute one of the three prevalent writing systems collectively referred to as Japanese script.
