What you'll learn in this article
Tabnine is an AI assistant that automatically completes code while you program. As you start writing code, the AI predicts what you want to write next and offers suggestions — it feels like having an experienced programmer right beside you, helping you along.
As of 2026, more than one million developers worldwide use it, and it's particularly favored in situations where corporate security is a priority. What sets it apart from other tools is that it can run entirely on your own computer without sending your company's code to the cloud (servers on the internet). This is called on-premises support. It integrates into popular editors (software for writing code) such as Visual Studio Code and IntelliJ IDEA.
Unfortunately, as of 2026, Tabnine no longer offers a free plan — all plans are paid. There are two main pricing plans.
The first is the Code Assistant plan, priced at $39 per month (approximately ¥5,800 JPY). It includes basic code completion features and is suited for individuals or small teams. The second is the Agentic Platform plan, at $59 per month (approximately ¥8,800 JPY). This includes more advanced features such as AI agents (AI that automatically handles tasks) and the ability to generate code from images. There is also a dedicated plan for enterprises, with separate pricing for organization-wide deployment.
Yes, Tabnine supports Japanese. If you type a question in Japanese in the chat feature within the code editor, it will respond in Japanese. For example, if you ask in Japanese, "Please write this function," the AI will understand and generate the code for you.
In terms of accuracy, data from enterprise users shows that approximately 90% of suggestions are accepted. However, the more specific your instructions are, the more accurate the generated code will be. For instance, rather than saying "create a button," writing "create a button with a blue background and rounded corners that shows an alert when clicked" is much more likely to give you the result you want. Tabnine also learns your coding style the more you use it, gradually offering more accurate suggestions tailored to you.
Tabnine permits commercial use. You can use code generated by Tabnine in work projects or products you sell without any problem.
Regarding copyright, Tabnine trains on publicly available code repositories (code published on platforms like GitHub). Copyright of the generated code basically belongs to you. However, since AI-suggested code may sometimes fall under open-source licenses (publicly available code with defined usage conditions), we recommend reviewing generated code for important projects. Tabnine's Enterprise plan also includes a feature that detects the risk of license violations.
Tabnine's biggest rival is GitHub Copilot. The major difference between the two lies in their approach to security and privacy.
GitHub Copilot is developed by Microsoft and OpenAI, offering broad suggestions and the ability to quickly generate a wide variety of code. Tabnine, on the other hand, excels in its ability to run entirely on your own computer or office server without sending your code to the internet. This is why organizations that prioritize this — such as financial institutions, healthcare companies, and government agencies — choose Tabnine. The Code Review Agent added in 2026, which automatically analyzes pull requests (code change proposals) and leaves comments, is also a distinctive strength unique to Tabnine. Tabnine is generally recommended for teams that prioritize accuracy and privacy, while Copilot is better suited for those seeking broad generation capabilities.
Unfortunately, Tabnine does not have a dedicated smartphone app. Since Tabnine works as an extension for desktop code editors (such as Visual Studio Code, IntelliJ IDEA, and PyCharm), it is fundamentally designed for use on a computer.
That said, it is possible to remotely access your computer from a smartphone or tablet and operate the code editor. For example, using SSH connections or Visual Studio Code's Remote feature allows you to indirectly use Tabnine from a smartphone. However, because of the small screen size, practicality is limited, and a computer is necessary for serious coding.
Tabnine's official website has detailed documentation (a manual) with thorough explanations of how to install and configure the tool. It is primarily in English, but tools like Google Translate can make it readable in Japanese.
You can also contact the official support team by email. Users on paid plans receive priority support and can get answers to technical questions. The Japanese user community is still small, but searching for "Tabnine エラー" (Tabnine error) or "Tabnine 使い方" (how to use Tabnine) on X (formerly Twitter), Qiita, or Stack Overflow may turn up solutions from others who faced the same issues. For beginners, starting with the "Getting Started" page in the official documentation is recommended.
In 2026, Tabnine was named a Visionary in the Gartner Magic Quadrant (a well-known IT industry evaluation report), a recognition that speaks to its high future potential.
Looking ahead, the enhancement of AI agent features is a key direction. With the addition of Image-to-Code (generating code from images) in 2026, as well as integration with Jira (a project management tool), Tabnine is evolving beyond simple code completion into a platform that supports the entire development workflow. The Enterprise Context Engine — a mechanism for sharing company knowledge with the AI — also allows the AI to learn your organization's unique coding rules and past projects, enabling suggestions optimized specifically for your team. For enterprises that want to protect their privacy while maximizing the power of AI, Tabnine will only become a more essential tool going forward.
If you're new to programming, start by checking the official website for detailed features and confirm whether it supports the editor you use. Check the official website for the latest information on whether a free trial period is available. With the help of AI, let's make coding more enjoyable and efficient.
