Overview

JetBrains AI Assistant brings AI-powered code completion, explanation, and generation directly into IntelliJ IDEA, PyCharm, WebStorm, GoLand, and every other JetBrains IDE — without switching to a different editor. Unlike Copilot which works as an extension, JetBrains AI is deeply integrated: it understands the full project context, suggests refactors, generates tests, explains errors with full stack trace context, and drafts commit messages from diffs. For teams committed to JetBrains IDEs who don't want to migrate to VS Code or Cursor just to get AI assistance.
