Smarter agents. Faster development. One professional IDE.

  • Develop confidently with AI

    Generating code quickly with AI is the easy part. Trusting the result is harder. IntelliJ IDEA closes the loop: Generate with AI, and then validate immediately with a debugger, test runner, and built-in inspections. Ship with confidence, not just speed.
