Overview

IntelliJ IDEA is JetBrains' IDE for Java and Kotlin development. It integrates AI models such as Claude, GPT, Gemini and Grok and agents including Junie, Claude Agent and Codex, paid for with JetBrains AI credits or your own subscriptions and API keys. The Ultimate edition adds a profiler, database tools, web development, Spring and Jakarta EE support, and cloud deployment.

Best for: Java and Kotlin developers who want an IDE with built-in AI agents and debugging tools
Pricing: The captured pages show no prices; pricing is only linked to from the navigation.

Strengths and trade-offs

Strengths

Day-one support for new Java releases, including early builds
Choice of AI models: Claude, GPT, Gemini, Grok or a local model
Bring your own AI subscription or API keys instead of credits
Logpoints inspect running state without editing source code

Trade-offs

Profiler, database, Spring and web tools are Ultimate-only
AI usage costs sit on top of the IDE, via credits or your own keys
2026.2 fixed 140 freezes, so performance has been a known issue
Pages describe Java and Kotlin work; other languages are not covered
