Updated March 10, 2026
Overview
JetBrains AI is the native AI assistant built into IntelliJ-platform IDEs (IntelliJ IDEA, PyCharm, WebStorm, etc.). It includes Junie, an autonomous coding agent that can plan and implement features, write tests, and handle multi-file changes. JetBrains AI leverages deep IDE integration for context-aware code understanding.
Windsurf (by Codeium) is an AI-powered IDE that combines copilot-style code completion with agentic multi-file editing capabilities. It features Cascade, a deep context engine that understands your codebase and can autonomously plan and execute multi-step coding tasks. Windsurf supports all major programming languages and provides both inline suggestions and chat-based coding assistance.
