JetBrains AI Assistant
Integrated AI coding assistance for JetBrains IDEs and VS Code
Our Review
JetBrains AI Assistant brings AI coding features into JetBrains IDEs and, in preview, into VS Code. It offers code completion, chat, and multi-file editing, with access to cloud models like GPT-4.1, Claude 3.7 Sonnet, and Gemini 2.5 Pro, plus local model support via OpenAI-compatible servers.
Strengths: The free tier includes unlimited code completion and limited cloud quotas, which is notable for developers already on JetBrains tools. RAG-based context and multi-file editing from chat work well for refactoring and documentation. JetBrains supports the Agent Client Protocol so you can plug in your own agents. SSO and BYOK are available for enterprise needs.
Tradeoffs: Full cloud access and higher quotas require AI Pro or AI Ultimate subscriptions, which tie into JetBrains All Products Pack or separate AI plans. VS Code support is still in preview, so feature parity may lag. There is no agentic “plan and execute” mode built in; chat and completion are the main interaction models.
Best for: JetBrains users who want seamless AI assistance without leaving IntelliJ, PyCharm, or other JetBrains IDEs. Also suitable for teams needing SSO, BYOK, or local model options.
Final verdict: JetBrains AI Assistant is the natural choice if you already use JetBrains. The free tier with unlimited completion and optional local models makes it competitive; paid tiers add cloud capacity and advanced models. Compare with GitHub Copilot or Cursor if you are primarily in VS Code.
