Exploring the JetBrains AI Assistant for Visual Studio Code
If you’ve ever wished your code editor could do more than just highlight syntax and catch the occasional typo, you’re not alone. The landscape of developer tools is shifting faster than ever, and artificial intelligence is now front and center—especially with the launch of JetBrains AI Assistant for Visual Studio Code. This isn’t just another plugin; it’s a reimagining of what an AI-powered coding partner can be, available to millions of developers who’ve made Visual Studio Code their home[1][3][4].
Let’s face it: the days of manually sifting through documentation or wrestling with obscure bugs are numbered. AI is already changing how developers write, review, and refine code, and JetBrains is staking a bold claim in this new frontier. As someone who’s followed AI in the developer space for years, I can’t help but get excited about this move. It’s not just a win for JetBrains fans—it’s a clear signal that AI-driven assistance is becoming the new standard, regardless of your preferred development environment.
The AI Assistant Landscape: Where JetBrains Fits In
To appreciate the significance of JetBrains AI Assistant’s arrival in Visual Studio Code, it’s worth taking a quick detour into how we got here. For years, JetBrains has been a heavyweight in the world of integrated development environments (IDEs), with tools like IntelliJ IDEA, PyCharm, and Android Studio dominating the landscape for many developers. Their AI Assistant was always tightly integrated into these platforms, leveraging deep context and advanced language models to provide intelligent code completion, refactoring, and error detection[1][3].
But here’s the thing: not everyone uses JetBrains IDEs. Visual Studio Code (VS Code) has surged in popularity, thanks to its lightweight design, extensive plugin ecosystem, and cross-platform support. Until now, JetBrains’ AI features were out of reach for the VS Code faithful. That changed on May 19, 2025, when JetBrains announced the public preview of its AI Assistant for VS Code—a move that’s already shaking up the developer community[1][4].
Deep Dive: JetBrains AI Assistant Features for VS Code
So, what can you actually do with JetBrains AI Assistant in Visual Studio Code? Quite a lot, as it turns out. Here’s a rundown of the standout features, all powered by JetBrains’ proprietary Mellum LLM:
- Context-Aware Code Completions: Whether you’re writing Java, Python, JavaScript, C#, C++, or TypeScript, the assistant offers smart, syntax-aware suggestions for single lines or entire blocks of code[5].
- Refactoring and Optimization: Ask the AI to refactor messy code, suggest optimizations, or identify potential bugs. Changes can be applied directly from the chat interface, streamlining your workflow[5].
- AI-Powered Chat: Interact with your codebase naturally. Ask questions, refine prompts, and get answers tailored to your specific project and language[5].
- Agentic Mode: This is where things get really interesting. Agentic mode orchestrates multiple models to solve complex problems under your supervision. You guide the AI as it tackles tasks, making it a true collaborator rather than just a code generator[5].
- Documentation and Commit Messages: Generate clean, language-appropriate documentation and commit messages automatically by analyzing your code changes[5].
Installation and Licensing: What You Need to Know
Getting started is straightforward. Head to the Visual Studio Code Marketplace, search for JetBrains AI Assistant, and click install. The extension is also available for other compatible IDEs, like Cursor or Windsurf, and can be installed via a .vsix file if the marketplace isn’t available[2].
During the public preview, you can log in with your JetBrains Account and either use your existing AI subscription or get a free AI EAP license. JetBrains AI plans will apply after the full public release, but for now, it’s open for everyone to try[2].
Comparing JetBrains AI Assistant with the Competition
How does JetBrains AI Assistant stack up against other AI coding tools? Let’s break it down:
| Feature | JetBrains AI Assistant (VS Code) | GitHub Copilot (VS Code) | Tabnine (VS Code) |
|---|---|---|---|
| Language Support | Java, Kotlin, Python, JS, C#, C++, TS | Most major languages | Most major languages |
| Code Completions | Syntax-aware, block-level | Line-level, block-level | Line-level, block-level |
| Refactoring | Yes, with chat and edit modes | Limited | Limited |
| Documentation Gen | Yes | Limited | No |
| Commit Message Gen | Yes | No | No |
| Agentic Mode | Yes | No | No |
| Customization | High (via JetBrains ecosystem) | Moderate | Moderate |
JetBrains AI Assistant stands out with its agentic mode and deep integration into the broader JetBrains ecosystem, offering features that go beyond simple code generation[5].
Real-World Applications and User Experiences
Early adopters are already reporting significant productivity gains. Developers mention that the assistant helps them understand unfamiliar codebases faster, catch subtle bugs before they become problems, and automate tedious tasks like documentation and commit messaging[4][5]. One developer shared, “It’s like having a senior engineer sitting next to you, ready to explain anything or suggest improvements—except it never gets tired or needs coffee.”
By the way, the assistant isn’t just for solo developers. Teams using VS Code can leverage the same AI features, making collaboration smoother and more efficient. This is especially valuable for distributed teams working across different time zones.
Historical Context: The Rise of AI in Coding
It’s worth remembering that AI-assisted coding is a relatively recent phenomenon. Just a few years ago, tools like GitHub Copilot were seen as revolutionary for offering basic code completions. Today, the bar is much higher. Developers expect AI to understand context, suggest optimizations, and even help with debugging and documentation[5].
JetBrains has been a quiet innovator in this space, focusing on deep integration and high accuracy. Their move to bring AI Assistant to VS Code is a recognition that the future of coding is collaborative, context-aware, and, most importantly, accessible to everyone—not just those using JetBrains’ own tools[1][3].
Current Developments and Industry Reactions
The launch of JetBrains AI Assistant for VS Code has been met with widespread enthusiasm. Industry analysts note that it’s one of the first major AI coding assistants to offer true agentic capabilities outside of a proprietary IDE[4][5]. This opens up new possibilities for developers who want the power of JetBrains’ AI without switching editors.
Interestingly enough, the timing couldn’t be better. The demand for AI-powered developer tools is at an all-time high, with companies racing to integrate LLMs into their workflows. JetBrains’ decision to go IDE-agnostic is a strategic move to capture a larger share of the market and stay ahead of competitors like GitHub and Tabnine[1][4].
Future Implications: What’s Next for AI-Assisted Coding?
Looking ahead, it’s clear that AI will play an even bigger role in software development. Tools like JetBrains AI Assistant are just the beginning. We can expect to see more advanced collaboration features, deeper integration with project management tools, and even AI-driven code reviews that catch not just bugs, but potential security vulnerabilities.
As someone who’s watched this space evolve, I’m thinking that the next big leap will be AI assistants that can understand not just code, but the broader context of a project—business requirements, user feedback, and even regulatory constraints. JetBrains is well-positioned to lead this charge, thanks to its focus on context and collaboration[3][5].
Different Perspectives and Potential Challenges
Not everyone is ready to embrace AI-assisted coding. Some developers worry about over-reliance on AI, the risk of generating insecure or poorly optimized code, and the potential for job displacement. These concerns are valid, but tools like JetBrains AI Assistant are designed to augment, not replace, human expertise. By keeping developers in the loop and giving them control over AI actions, JetBrains is addressing some of these fears head-on[5].
Final Thoughts: AI-Assisted Coding for Everyone
The arrival of JetBrains AI Assistant in Visual Studio Code is a milestone for the developer community. It’s proof that AI-powered coding is no longer a luxury reserved for users of proprietary IDEs—it’s becoming a standard feature for all developers, regardless of their toolchain[1][3][4].
As we look to the future, it’s clear that AI will continue to reshape how we write and maintain software. Tools like JetBrains AI Assistant are leading the charge, making coding faster, smarter, and more collaborative than ever before.
