JetBrains AI
A native AI coding platform in JetBrains IDEs that lets developers freely pick models and agents to accomplish the full development workflow—from code generation to debugging and scaffolding.
Tool overview
Adoption evidence: Official JetBrains tweets have generated high attention (e.g., one with 175K views, 947 likes), but evidence is mostly official announcements and community introductions; in-depth third-party reviews are scarce. However, the 2026.1 release with deep AI integration and an open ACP protocol to support external agents like Cursor and Codex signals a concrete shift from traditional IDE to open AI-powered platform. Community sentiment is largely positive and expectant, though solid hands-on reports are still limited. What it does: While coding, developers can invoke Claude, OpenAI Codex, or custom models via chat, context menus, or the dedicated Junie agent for code completion, explanation, refactoring, test generation, and debugging. Junie can plan tasks, debug using IDE tools, and run long-running operations in the background. The ACP protocol further allows agents like Cursor, Qoder, TRAE, and CodeBuddy to work directly inside the IDE, giving access to multiple AI capabilities without switching tools. Barrier & cost: It requires a recent JetBrains IDE (e.g., IntelliJ IDEA 2026.1).
