Cursor vs JetBrains AI

Cursor and JetBrains AI Assistant represent two approaches to bringing AI into your development workflow: a new AI-native IDE versus an AI plugin for established professional IDEs.

Overview

Cursor is a VS Code fork rebuilt from the ground up as an AI-first editor. Every feature — from tab completions to the Composer multi-file editor to the chat panel — is designed around AI interaction. It indexes your full codebase for context. JetBrains AI Assistant is an AI plugin for IntelliJ IDEA, PyCharm, WebStorm, and other JetBrains IDEs. It adds inline completions, AI chat, code generation, documentation writing, and commit message generation to the existing JetBrains experience.

Key Differences

AI integration depth: Cursor's entire UX is built around AI — Composer mode, inline diff previews, and codebase-wide context are deeply embedded. JetBrains AI is an add-on layer that enhances existing features but does not redesign the editor around AI. IDE maturity: JetBrains IDEs have decades of refinement in refactoring, debugging, testing, and language support. Cursor inherits VS Code's ecosystem but lacks JetBrains' deep language-specific intelligence. Language support: JetBrains IDEs provide best-in-class support for specific languages (Java in IntelliJ, Python in PyCharm). Cursor treats all languages more uniformly through its VS Code foundation. Multi-file editing: Cursor's Composer mode is purpose-built for AI-driven multi-file edits. JetBrains AI can generate and modify code but does not have an equivalent orchestrated multi-file editing experience.

Pricing

Cursor Pro is $20/month. JetBrains AI Assistant requires a JetBrains IDE subscription plus the AI add-on at $10/month (included with All Products Pack). Total JetBrains cost is higher but includes the full IDE.

Verdict

Choose Cursor if you want the deepest possible AI integration and are comfortable in a VS Code-based environment. Choose JetBrains AI if you rely on JetBrains' superior refactoring, debugging, and language-specific features and want AI as an enhancement to that experience. JetBrains users rarely switch to Cursor; VS Code users often do.
