A productive coding session often depends on maintaining focus. However, small interruptions, like switching to a browser to look up syntax, debug an error message, or write boilerplate code, can break that concentration. Each context switch can disrupt a developer's workflow.
AI assistants aim to solve this by acting as a coding partner inside your IDE. They can generate code, explain concepts, and handle repetitive tasks, helping you stay focused.
With numerous options available in the JetBrains Marketplace, it can be difficult to identify which plugins offer the most utility.
To help, we tested several popular JetBrains plugins to evaluate their performance and features in 2025. Here is a summary of our findings.
What are ChatGPT plugins for JetBrains?
Simply put, these plugins are extensions that plug Large Language Models (LLMs) from companies like OpenAI, Google, and Anthropic right into your JetBrains IDE, whether you're using IntelliJ IDEA, PyCharm, or WebStorm.
They act like a direct line to a smart coding assistant that knows what you're working on. They can answer coding questions using the context of your codebase, generate code snippets or unit tests, refactor and explain existing code, and even suggest fixes for errors.
The goal is to stop you from having to leave your IDE for every little thing. By bringing the tools and answers directly to you, these plugins help you maintain focus and get more done. Here’s a visual breakdown of how they work.
Criteria for evaluating ChatGPT plugins for JetBrains
Not all AI plugins are created equal. To keep this comparison fair, I judged each one on a few things that really matter when you're actually coding.
- Deep IDE Integration: Is it just a chat window slapped on top of the IDE, or does it feel like it belongs there? I looked for features that are part of the natural workflow, like context-aware code generation or right-click error analysis.
- Context Awareness: Does the AI actually get what you're doing? The best plugins can understand your whole project, not just the single file you have open. That's what separates a generic answer from a useful one.
- Model Support and Flexibility: Are you stuck with one AI provider? I favored plugins that let you use different models from various companies. It's also a big plus if you can connect to local models or bring your own API keys (BYOK).
- Privacy and Security: This is a big one. Nobody wants to send their company's code to some random third party. I dug into each plugin's privacy policy to see if they use your code for training and how they manage your data.
I haven't actually used it much. But I believe a lot of the poor ratings might be from when it was introduced and installed as a default plugin, which worried a lot of people concerning corporate compliance, control of their data or general privacy issues.

A detailed look at three popular ChatGPT plugins for JetBrains
Now for the details. I’ll walk you through how each plugin actually performs, who it's best for, and where it might fall short.
1. JetBrains AI Assistant
First up is the official tool from JetBrains itself. This plugin is built to feel like a natural part of their IDEs and is already used by developers at big names like Volkswagen, Shopify, and Tesla.
Why it's on the list Its biggest advantage is how seamless it is. The integration is incredibly deep. Features like context-aware AI chat, commit message generation, and inline error explanations are baked right into the workflow you already know. It doesn't feel like an add-on; it feels like it belongs.
JetBrains is also serious about privacy, stating clearly that your code is not used for training. The service is SOC 2 Type II compliant, which is a huge plus for enterprise teams. It gives you access to top models from OpenAI, Anthropic, and Google, and even lets you connect to local models with tools like Ollama if you want to work completely offline.
What could be better While there's a free tier with some basic functions, you need a paid subscription to unlock its full potential. The AI Pro plan costs about $100/year for individuals.
Who it's for This is the best option for developers and teams who want stability, security, and a polished, native experience. If you’re willing to pay for a premium tool that’s officially supported and just works, this is it.
2. ChatGPT - EasyCode
EasyCode is a popular third-party plugin with over 1.1 million downloads. It aims to be a super-powered assistant by indexing your entire codebase for better context.
Why it's on the list Its main draw is flexibility. EasyCode supports a huge range of the latest models, including GPT-4.1, Gemini 2.5 Pro, and Claude 3.7 Sonnet. The idea of indexing your whole codebase is also interesting, as it could deliver suggestions that are far more relevant than what you'd get from a tool that only looks at a single file.
What could be better User reviews for the plugin are varied, with a 3.8-star rating. Some users have noted issues with certain features, such as "Quick fix with EasyCode" getting stuck in a loop. Additionally, there is some confusion regarding API key usage. The official pricing page clarifies that using your own API keys is not currently supported, which means users must subscribe to one of their paid plans. Plans start at $200/month for the "Finisher" plan.
Who it's for This plugin is for developers who want to experiment with the widest possible array of LLMs. If that flexibility is your top priority and you're okay with a third-party subscription, EasyCode is worth checking out.
3. ChatGPT - Fully customizable
Developed by Next Code Gen, this plugin takes a much simpler approach: it connects your IDE directly to your own OpenAI account.
Why it's on the list Simplicity and control are its main strengths. Instead of another subscription, this plugin lets you use your own OpenAI token. This means you only pay for what you use and have full control over which model you're using. You can tweak everything from the model version to the temperature settings in a simple "chatgpt_plugin.yaml" config file. It's also a win for security, as it communicates directly with OpenAI's API, so your code never passes through the developer's servers.
What could be better This is a no-frills tool. You get a chat interface and some configuration options, but it lacks the deep IDE integration or advanced codebase indexing you'll find in the other two. It’s more of a direct line to OpenAI than a complete AI assistant.
Who it's for This is perfect for developers who already have an OpenAI API key and just want a straightforward chat interface inside their IDE. If you value control and don't want another subscription, this is a great, lightweight option.
Beyond coding: AI for your entire workflow
Getting the right AI in your IDE is a great start, but it only solves one part of the puzzle. Real productivity comes from streamlining your entire development process, and that includes everything that happens outside your code editor.
Think about how much time your team wastes digging through Confluence pages, trying to find that one Google Doc with a checklist, or asking the same questions over and over in Slack. These interruptions break your focus just as much as switching away from your IDE.
This is where an AI teammate designed for internal knowledge can really help. Instead of just a coding assistant, an AI Internal Chat from eesel AI plugs into all your company's knowledge sources. Your team can ask questions like "What are the new API rate limits?" or "How do I set up the local dev environment?" right from Slack and get instant answers with links to the original documents. It frees up senior devs from being a human search engine and helps new hires get up to speed much faster.
Seeing these tools in action can often provide the best sense of how they fit into a real coding workflow. The official video from JetBrains, for example, offers a great walkthrough of how their AI Assistant integrates directly into IntelliJ IDEA to help with tasks like code generation and refactoring.
