Frequently Asked Questions

  • How can you tell if a name is male or female?

    Most names are predominantly used for either males or females, so a statistical approach will often yield good results. Of course, some names are used across both sexes, but a statistical approach will reveal that, too. Furthermore, naming conventions can rely on cultural differences. We cover that with support for scoping a lookup to a specific country .

  • How accurate is the tool in determining gender from names and how does it handle unisex names?

    Our predictions are based on the ratio of males to females with a given name. As such, the accuracy is based on whether a name is strictly used by one gender or as a unisex name. We return a probability with all predictions. A probability closing towards 50% means that both genders use the name with equal likelihood.

  • How do I perform gender checking on no-code platforms like Zapier and Make?

    We have official apps for most no-code platforms. You can read more in our guides on name-to-gender checking in no-code tools

  • How does the tool handle names from different cultural or ethnic backgrounds?

    Naming conventions can be different across countries and cultures. We support scoping a classification to a specific country which will often improve the accuracy of your results.

  • Do you offer any free plans?

    We do - and you won't even have to sign up. You can process 100 names/day with our API or CSV tool and we'll limit you based on your IP.

  • Can the tool be integrated with our customer relationship management (CRM) systems?

    There's plenty of ways to start integrating our prediction services with your existing tools. The easiest way to get started is with our official no-code apps for Zapier, Make and Pipedream.

  • What kind of customer support do you offer?
