So What Kind of Tool Is JetBrains AI Assistant, Anyway?

JetBrains AI Assistant is an AI assistant that works within JetBrains programming environments such as IntelliJ IDEA and PyCharm. It doesn't just autocomplete code — it can answer your questions through an AI chat interface and automatically generate tests for you.

What sets it apart from other tools is its ability to understand not just the file you currently have open, but the structure of your entire project. This allows it to make accurate suggestions even for complex code. Starting in 2026, an autonomous agent feature called Junie and Claude Agent integration have also become available.

Q1: Can I Use It for Free? How Much Does It Cost?

JetBrains AI Assistant offers four pricing plans. The AI Free plan is free of charge, but it only provides 3 credits per month (roughly 3 uses), and it cannot be used with Community Edition. For serious use, AI Pro ($10/month) or AI Ultimate ($30/month, or $20/month when billed annually) are recommended.

If you already hold a paid JetBrains IDE license, you may be able to use AI Assistant at no additional cost. Paying annually gives you a 17% discount, so an annual contract is the better deal if you plan to use it long-term. An Enterprise plan with custom pricing is also available for businesses.

Q2: Can I Use It in Japanese? How Accurate Is It?

Yes, you can use it in Japanese, though some configuration may be required. The official documentation is available in Japanese, so even first-time users can get started with confidence. When you ask questions in Japanese through the AI chat, you'll receive responses in Japanese.

As for accuracy, it is considered to be at a practical, usable level. It's not perfect, but being able to ask for code explanations and error solutions in Japanese is a huge help for beginners. It lowers the barrier to learning programming even for those who aren't comfortable with English.

Q3: Is It Okay for Commercial Use? What About Copyright?

Code generated by JetBrains AI Assistant is generally considered usable in commercial projects. However, since the law hasn't fully caught up with the question of copyright for AI-generated code, we recommend consulting your company's legal department for important projects.

The Enterprise plan offers enhanced management and security features for businesses. Starting in July 2026, a JetBrains Central Console feature was also added, allowing companies to centrally manage AI credits across their IDE licenses. If you want to use it safely as a team, this is worth looking into.

Q4: How Does It Compare to Competing Tools?

Compared to other AI coding tools like GitHub Copilot and Cursor, the strength of JetBrains AI Assistant lies in its deep integration with the IDE (integrated development environment). Rather than simply looking at the current file, it understands the semantic structure of the entire project.

Interestingly, as of June 2026, an integration with GitHub Copilot was also announced. GitHub Copilot can now be selected from within the JetBrains AI Assistant chat, allowing you to switch between whichever you prefer. It also supports OpenAI-compatible endpoints (such as LM Studio and Llama.cpp), giving you the flexibility to choose your preferred AI model.

Q5: Can I Use It on My Smartphone?

Unfortunately, JetBrains AI Assistant is exclusive to the desktop IDE and cannot be used in a smartphone app. You'll need a computer with a JetBrains IDE installed — such as IntelliJ IDEA, PyCharm, Rider, or WebStorm.

That said, it works on Windows, Mac, and Linux, so any computer will do. Since programming and development work is generally more efficient on a larger screen, the lack of smartphone support is unlikely to be a major issue.

Q6: What Should I Do If I Get Stuck?

JetBrains' official documentation is available in Japanese, so that's the best place to start. If you're unsure how to use something, you can also try asking the AI Assistant itself in Japanese — just say "teach me how to use this." It's a surprisingly effective approach.

The official JetBrains blog also regularly features update news and use-case examples. You can also ask questions on the community forum or Stack Overflow. When you encounter an error, pasting the error message directly into the AI chat and asking what's causing it is a great way for beginners to find a path to a solution.

Q7: What's Next for JetBrains AI Assistant?

2026 is shaping up to be a year of major evolution. Rider 2026.2, released in July, added refactoring skills for AI agents, making code rewrites faster and more cost-effective. In PyCharm 2026.2.1, AI agents can now be used within Jupyter notebooks — a tool widely used in data analysis.

Furthermore, a new feature called JetBrains Context has been released in early access. This is an intelligence layer designed to help AI work efficiently even in large codebases. Going forward, AI assistants are expected to play an increasingly active role not just for individual developers, but in team-based development at companies as well.

Wrapping Up: Taking Your First Step

JetBrains AI Assistant is a powerful ally for programming beginners. Here's a summary of the key points from this article:

• A free plan is available, but a paid plan at $10–$30/month is recommended for serious use
• Japanese is supported at a practical level of accuracy, and official documentation is available in Japanese
• Commercial use is possible, but consult legal for important projects
• Flexible usage thanks to GitHub Copilot integration and support for multiple AI models
• No smartphone support, but desktop IDE integration is among the best in the industry
• Ongoing feature enhancements throughout 2026, with increasingly robust enterprise management capabilities

Start by trying the free plan, and if you like it, switch to a paid plan. If there's anything you don't understand, try asking the AI chat in Japanese. It should help accelerate your programming journey.
