Cursor AI Coding Assistant Is Now Available in JetBrains IDEs

Cursor, one of the leading AI-powered coding assistants, continues to expand its capabilities. It can now work fully with IntelliJ IDEA, PyCharm, WebStorm and other JetBrains Integrated Development Environments (IDEs). This groundbreaking integration was made possible by the Agent Client Protocol (ACP), which lets AI agents communicate with standard development environments. As a result, your productivity during development will multiply.

Boundless Integration With the Agent Client Protocol (ACP)

One of the features developers have long been waiting for was the ability to use their favorite AI tools inside the IDEs they already use and whose shortcuts and plugins they know inside out. JetBrains IDEs have become an industry standard with their powerful debugging, code analysis and refactoring features. Cursor integrating into these environments means combining the best features of both worlds.

The Agent Client Protocol (ACP) lays the groundwork for Cursor to work seamlessly in JetBrains environments, like a native plugin or assistant. ACP passes the IDE's context, open files, the project's directory structure and semantic code relationships to the AI model. This way, the AI understands the codebase just as you know your own project, and offers context-aware code generation, bug fixes and architectural suggestions. To be clear, ACP is much more than a simple text completion tool; it is a dynamic bridge that can read the state of your project.

Direct Access to Frontier Models

One of the biggest advantages of the new system is that it gives developers unrestricted access to the latest AI models from OpenAI (GPT-4.5 etc.), Anthropic (Claude Opus 4.6, Sonnet 4.5 etc.), Google (Gemini 3 Pro/Ultra) and the models Cursor trains itself. Developers can choose the model they want based on the complexity of the application:

• Claude for verbal reasoning and code analysis.
• For mathematical problem solving and building an architecture from scratch, you can call frontier models such as GPT or Gemini from inside the IDE with just a few clicks.

This puts an end to the "should I paste this code into ChatGPT or Claude?" dilemma. From a single interface, you can blend the world's most advanced (state-of-the-art) models with your project's code.

Secure Codebase Indexing and Semantic Search

One of the biggest concerns of developers, and especially companies, when adopting AI tools is security: "Will my code be used to train AI companies' datasets?"

Cursor's new integration offers Secure Codebase Indexing. Your codebase is read by the AI only to answer you and in line with enterprise security standards, and it is never shared with third parties or used to train public models.

On top of that, indexing gives you an excellent Semantic Search experience. Your IDE can answer questions asked entirely in natural language, such as "Where did we call the database functions that update user data?", by pointing directly to the file and line. It frees you from the Ctrl+F / Cmd+F loop and helps you understand the project at an architectural level.

Free Access for Paid Cursor Users

As a clear strategy, the JetBrains integration is offered free of charge directly to users on paid Cursor plans (Pro etc.). So if you already have a Cursor subscription, you do not have to change your development environment or pay extra for additional plugins. This feature comes directly inside your plan and adds huge value. You will be able to experience the AI revolution without interruption, doubling your productivity on your projects while protecting your budget.

Version Compatibility and Easy Setup

The system requirements to benefit from the integration and be part of this new era are quite reasonable. This powerful tool requires the following:

1. JetBrains IDE Version: 2025.3.2 or later (IntelliJ, PyCharm, WebStorm, Rider, PhpStorm etc.) 2. AI Assistant Plugin: The official AI assistant plugin, which can easily be downloaded from the JetBrains plugin marketplace, needs to be installed and active.

The setup is practical and effortless: open the AI chat section inside JetBrains, find Cursor and integrate it. Thanks to this modular structure, you can power up your development environment within seconds.

An Open Ecosystem Strategy Independent of Any Single Authority

The freedom JetBrains offers is not limited to Cursor; the company's core vision is to free developers from what is called "vendor lock-in". Instead of imposing its own AI assistant, JetBrains has designed its platform like an open marketplace. The message it gives to companies' technology leaders, CTOs and independent developers is very clear: "Choose whichever AI assistant is best for you, but keep writing your code in our IDEs, which you are used to and which offer one of the best toolsets in the world."

This strategic move shows both that JetBrains prefers to grow in harmony with its competitors rather than stealing their market share, and that it puts the user's well-being first. Teams like Cursor, which pursue independent and autonomous (agentic) goals in particular, get the chance to invest in product quality while benefiting from JetBrains' solid enterprise network.

Looking Ahead: Autonomous Coding Assistants

The collaboration between Cursor and JetBrains IDEs is living proof that AI's role in developer productivity has evolved from simple autocomplete to context-aware assistants that understand the whole project; in short, a journey toward autonomous software production. AI does not just write code; it guides large refactoring jobs, spins up boilerplate code in seconds and interprets merge conflicts to suggest the most accurate solution.

The widespread entry of AI components with agentic features into projects is starting a golden age for software production. Rather than taking developers' jobs away, it is becoming a lever that can multiply their productivity 10 or even 100 times.

In conclusion, having a powerful AI assistant inside the IDE is no longer a "luxury"; it has become a must-have tool for today's modern developer. Thanks to this harmonious fit between Cursor and JetBrains, developers can step into a clean and futuristic development experience free of technical debt.

These autonomous AI integrations, which were only imagined 18 months ago, will rewrite the software development methodologies of the years ahead. How ready is your team for this change? Your new AI orchestrator, Cursor, is waiting for you at the junction point of your IDE!
