1. What is an AI Translation Tool?
AI translation tools are tools that automatically translate languages using artificial intelligence (AI). They utilize technologies such as machine learning, natural language processing, neural networks, and deep learning to translate from one language to another. This facilitates communication and information sharing between different languages.
AI translation became widely known when Google announced the Google Neural Machine Translation (GNMT) in 2016 and began offering it to users. GNMT significantly improved accuracy over the traditional Google Translate service by utilizing deep learning.
Since then, deep learning has been adopted by other companies, leading to the emergence of more fluent automatic translation services like DeepL. In 2020, Google refreshed its neural network and introduced a technology called Transformer. As a result, both speed and accuracy have further improved.
This Transformer technology is used not only for translation but also in generative AI that has gained attention in recent years, such as OpenAI's ChatGPT, Google's Gemini, and Anthropic's Claude.
The basic features of AI translation tools include not only text translation but also file translation such as Word documents, glossaries, and translation memories. By utilizing these features, the translation process becomes more efficient and the accuracy of translations improves.
2. Benefits of AI Translation Tools
We will explain the benefits of AI translation tools.
●Cost Reduction and Time Savings through Translation Automation
By utilizing translation automation, it is possible to significantly reduce the costs and time associated with translation. Compared to manual translation work, leveraging translation software and AI allows for efficient document translation. Companies and organizations can perform multilingual translations in a short time while also keeping costs down.
●Improvement of Translation Accuracy
Another advantage of AI translation tools is the improvement in translation accuracy. Compared to traditional machine translation, the number of mistranslations has significantly decreased. Additionally, because AI translation tools learn from vast amounts of data, they can achieve high accuracy in translating specialized terminology and specific fields. Therefore, they are also suitable for translating professional documents and technical terms.
●Support for Multiple Languages
The AI translation tool's ability to support multiple languages is also a benefit. This allows companies to communicate smoothly with overseas branches and customers. It is a very convenient tool for companies aiming for global expansion, as it enables smooth transactions with different language regions. By utilizing the AI translation tool, efficient and accurate translations can be performed, which is expected to greatly contribute to business expansion.
3. Top 5 AI Translation Tools
Here are 5 automatic translation tools equipped with AI.
Google Translate
Google Translate is a widely used free AI translation service available on computers and smartphones. It supports over 100 languages. File translation is also possible. However, it is not recommended for business use as the input data may be reused for service improvement.

DeepL
DeepL is a popular automatic translation service known for its high fluency. It features file translation and glossary functions, and it also allows for the specification of casual and polite forms in Japanese translations. Compared to other services, it supports a limited number of languages, with 31 in total, but it covers the major languages. Recently, a proofreading support service called DeepL Write for English and German has been launched. In DeepL's free plan, the input data is reused for service improvement, but in the paid plan, confidentiality is maintained, making it safe for business use. For more details on DeepL's confidentiality policy, please see the article below.

ChatGPT
OpenAI's AI chat service, ChatGPT, can also be used as an AI translation tool. By writing "translate to Japanese" in the chat box and then entering the text to be translated, it will be translated. There are no glossary or formal/informal style specification features, but the translation can be altered based on the instructions in the chat box. For more details on how to use ChatGPT for translation, please see the article below.

Microsoft 365
The office applications Word, Excel, PowerPoint, and Outlook are equipped with AI translation features. They support text translation and file translation (Word only). Glossaries and the specification of casual or polite forms cannot be set. Since the input and output data used for automatic translation in any of the applications are not reused, they can be safely used for business purposes. For more details on how to translate in each application, please refer to the blog article below.

MTrans Team
Our Human Science's "MTrans Team" is a tool that allows you to translate documents such as Word, Excel, PowerPoint, and PDF simply by dragging and dropping them into a web browser. You can choose from six translation engines: ChatGPT, Google, Microsoft, Papago, Claude, and Yaraku Translate. Since all engines are connected via API, the input and output data are not reused. You can register glossaries and phrase collections, which can reduce the time spent on post-translation editing. For more details about MTrans Team, please visit the product page below.
4. How to Choose AI Translation Tools
We will explain how to choose AI translation tools.
●Translation Accuracy
The accuracy of AI translation varies by service. In addition to accuracy, the fluency of the translation can also differ. For example, DeepL tends to produce more fluent translations compared to other services. The choice of service depends on whether you prioritize accuracy or fluency. Additionally, whether or not you can use glossary and formal/informal language specification features also affects translation accuracy. If you frequently translate product names or technical terms in your business, it is recommended to choose a service that has a glossary feature to improve the accuracy of translations.
●Supported Languages
Most AI translation services support a wide range of languages and can translate between major languages. If you need to use a minor language for business purposes, you will need to use an AI translation service that supports that language.
●Cost Performance
By using AI translation services, you can significantly reduce costs compared to human translation. However, AI translations may contain errors or omissions, so human revision is necessary. The overall cost of the translation work depends on how much you can reduce this revision work. Therefore, it is important to choose a service with high translation accuracy. Many AI translation services have a fixed monthly or annual fee based on the number of users, with the price per user being around a few thousand yen per month.
●Functionality and Usability
The presence of a glossary is important from a functional perspective. Especially in business contexts where specialized terminology is frequently translated, utilizing a glossary feature can significantly improve translation accuracy and reduce the need for manual corrections. As a result, the overall cost and duration of the translation work can be reduced. Usability varies depending on the situations that require translation. If you often need to translate Word documents, an AI translation service that can translate Word files directly is convenient. It's not only about being multifunctional; having a clear and user-friendly UI is also an important point.
●Level of Security Measures
AI translation services implement thorough security measures to protect user privacy and confidential information. Encryption technology is used during communication, and data storage and access control are strictly managed. AI translation services adhere to high security standards and employ various measures to ensure safety. However, some AI translation services may reuse user data for service improvement. Free services like Google Translate and the free plan of DeepL fall into this category. To prevent information leaks, it is essential to use services or plans that do not involve secondary use of data.
●Availability of Post-Editing Services
More companies are offering post-editing services after AI translation services. Post-editing services involve humans improving the quality of sentences after translation by AI systems, and are useful when the quality of AI translation alone is not sufficient. Our company, Human Science, provides post-editing services. For more details, please see the page below.
