AI-powered coding assistance integrated into JetBrains IDEs.
Grade: A — Score: 88/100
JetBrains AI Assistant leverages advanced AI models to integrate seamlessly into JetBrains IDEs, offering features that enhance coding efficiency and accuracy. It utilizes context from your project, such as the currently open file and selected code, to deliver relevant suggestions and insights.
The workflow is designed to be intuitive: users can interact with the AI through chat or directly in the editor, allowing for real-time code generation, explanations, and improvements. This integration supports a variety of coding tasks, from simple code completion to complex multi-step development processes.
While the AI Assistant significantly boosts productivity, users should be aware of potential risks, such as reliance on AI-generated suggestions that may not always align with best practices or project-specific requirements. Continuous human oversight is essential to ensure code quality and maintainability.

Consider switching to GitHub Copilot: GitHub Copilot offers similar AI-driven coding assistance but is integrated with a broader range of development environments.
JetBrains AI Assistant is the broader AI layer inside supported JetBrains IDEs, covering chat, in-editor generation, completion, code explanations, refactoring help, and access to coding agents. Junie is JetBrains' autonomous coding agent for larger multi-step tasks such as planning changes, editing multiple files, running tests, and executing terminal commands. JetBrains describes the distinction as AI Assistant helping you code faster while Junie lets you delegate whole development tasks.
Yes. GitHub Copilot is now an integrated agent in JetBrains AI Assistant and authenticates through your GitHub account using OAuth. It requires a separate active GitHub Copilot subscription and is not included with a JetBrains AI subscription or activated through BYOK.
Yes. JetBrains AI Assistant supports BYOK for compatible third-party providers, letting you use supported chat and AI Assistant features without a JetBrains AI subscription. Feature availability depends on the provider and model, and some integrated agents have different authentication rules, so BYOK does not reproduce every JetBrains AI subscription capability.
JetBrains calculates AI Credit use dynamically from factors such as token volume, model cost, and the amount of context sent with a request. Individual AI Pro currently includes 10 AI Credits per 30 days and AI Ultimate includes 35, and JetBrains estimates one credit at about 10 AI Chat code-generation requests or about 40 in-editor code-generation requests, although actual usage varies. Long chat histories, expensive models, and agent mode can consume credits substantially faster.
BYOK usage does not consume JetBrains AI Credits; the third-party provider bills that model usage directly. JetBrains also routes provider-account agent usage through that provider rather than the JetBrains AI quota, while requests made through the JetBrains AI service consume its credits. JetBrains documents Next Edit Suggestions and Code Completion as not consuming AI Credits.
Under the current JetBrains AI Terms, JetBrains says it will not use your inputs, data, outputs, or suggestions to train generative language models unless you expressly agree. Detailed code-related data sharing can include full prompts, responses, and code fragments and can be used to train JetBrains models, but it is disabled by default for commercial users unless explicit consent is given. JetBrains' separate non-commercial licensing rules can enable detailed collection by default with an opt-out, so license type matters.
No. JetBrains documents that Junie respects `.aiignore`, but Claude Agent, Codex, and GitHub Copilot currently do not, so those agents can process files listed there. A `.noai` file disables JetBrains AI Assistant for the project, but JetBrains notes that it does not control separate third-party AI plugins or other external tools.
Yes. JetBrains AI Assistant can connect to locally hosted models through Ollama and LM Studio and can assign compatible local models to chat and selected AI features. JetBrains currently uses a 64,000-token default context window for local models, and MCP tools cannot be invoked through configured MCP servers while a local model is being used. Some AI Assistant features also require particular model capabilities, so local-model support is not feature-for-feature identical to JetBrains AI.
JetBrains documents AI Assistant for IntelliJ IDEA, PyCharm, WebStorm, Rider, GoLand, PhpStorm, CLion, DataGrip, DataSpell, RubyMine, RustRover, and other supported JetBrains environments, with additional support for Android Studio and ReSharper. AI Free is more restricted: JetBrains says it requires IDE version 2025.1 or later and is unavailable in Android Studio, IntelliJ IDEA Community Edition, PyCharm Community Edition, and PyCharm Unified when used for free.
JetBrains AI Assistant keeps AI chat, code actions, multiple agents, BYOK, and local-model support inside JetBrains IDEs, while Cursor is a standalone AI-focused editor with its own agent and cloud workflow. Cursor currently lists Pro at $20 per month and Teams Standard at $40 per user per month with SAML/OIDC SSO, while JetBrains AI Pro is $10 per month for individuals and JetBrains positions advanced SSO and SCIM in AI Enterprise. The practical tradeoff is staying inside a full JetBrains IDE versus adopting an editor built around AI-first workflows.
