What we do

  • Learning English with your AI-buddy
  • "Speak for the Future" is our slogan

Our vision is for everyone to acquire true English speaking skills using AI English conversation technology.

Our company appArray is a start-up company developing the app SpeakBuddy. Our app utilizes voice recognition, AI conversation, and digital pronunciation technology to teach English conversation skills to our users. SpeakBuddy recently reached number one on the app store's Education App ranking and our number of users is continuing to grow.

SpeakBuddy has been listed on the app store's recommended app list many times and we are aiming to develop and provide the ideal foreign language acquisition experience to our users.

Why we do

  • Towards a multi-lingual world
  • Aiming for global talent

Our mission is to create a multilingual age.

We believe that if you can speak another's language, you can reach not only their minds, but their hearts as well and that by speaking a foreign language, your life will become richer.

However, because it is rare for most people to have a large amount of in person conversations that are necessary to acquire a foreign language, we believe that it is absolutely necessary for us to develop this sort of language learning app, where an AI robot can become a user's conversation partner.

We want to provide people who want to live and work abroad a more modern way to study foreign languages, and expand their life choices.
Through our work, we hope to create a world where we can help as many people do this as possible.

How we do

  • Developing a world-leading service
  • Effective communications

As a company, we are trying to create a dream team of AI conversation developers while also aiming to be a professional start-up company.
Our chief Server Engineer did a doctorate in Computer Science in Europe. Our Lead Client Side Engineer came from a large game development company and graduated from a university that specialized in foreign languages. Our Designer came from a top design firm in Australia. And, our CEO worked at an investment bank with foreign clients, became a certified accountant at the youngest possible age, and has a TOEIC score of 985 points. Many of our other team members also speak English at a native level.
