JetBrains IDEs
Code your way. Ship with confidence.
Prompt an agent or write it yourself – JetBrains IDEs make sure your code holds up either way.
One place to run agents and verify their work,
with jetbrains air
Configure how you work
Choose how each agent launches, in the GUI or the terminal, and what the IDE keeps front and center – your code or the agent session.
Move in parallel without losing context
コードベースの状態やコンテキストをそのたびに説明し直すことなく、1つまたは複数のプロジェクトで複数のエージェントを同時に使用できます。
Keep track of every session
実行中、完了済み、または対応待ちのセッションを確認できます。diffの該当行にコメントを付けて、対応をエージェントに差し戻せます。
コードが動作することをレビューして確認
Debugging, testing, profiling, and databases are all one click away, so you can confirm that nothing breaks before you merge the change.

AI agents perform better with JetBrains Rider's refactoring engine (read the study):
83%
faster
64%
lower cost
63%
fewer tool calls
Deterministic tools for you and your agents
IDE のコードインテリジェンスにより、コードベース全体のすべての使用箇所、依存関係、および型が解決されます。そのため、エージェントの消費トークンと誤ったターンを削減できます。
自分のエージェント、モデル、サブスクリプション
Connect the agents you use and run them on your own API key, the subscription you already pay for, or JetBrains AI. Switch subscriptions anytime, even during a session.

Why developers rely on JetBrains IDEs
Siva
@sivalabs
“I have been switching between Codex Desktop app and IntelliJ IDEA. With Air plugin, IntelliJ IDEA provides a good Agentic IDE experience. Less tool switching, less headaches.”
Deepak Gupta
Founder, Cybersecurity Architect, and Writer
“The JetBrains family remains the most capable option when you need an IDE that actually understands your language's semantics: Safe rename across a codebase, structural search and replace, and framework-aware completion are all deeper here than anywhere else.”
Greg Finzer
@GregFinzer
“I am really liking JetBrains Rider. The refactoring tools are great plus the built in database editor is so nice.”
Roman Zayac
Veltrix AIのQAエンジニア
“JetBrains tools are top-notch – reliable, smart, and built for productivity. IntelliJ IDEA and PyCharm have completely changed how I code. Excellent UX and constant innovation from the team.”
Peter
Developer at Dadroit
“Our primary IDE for all Dadroit products. The deep code intelligence, built-in tooling, and refactoring capabilities make a real difference when working on performance-critical applications like V Web.”
Jenni
Co-Founder of AIVory
“Our IDE of choice for many years and many products with awesome people behind it.”

よくある質問
Agents work task by task. An IDE helps you see how a change fits with the rest of the codebase, check what it affects, run and debug it, and refactor it safely before shipping code to production.
はい。編集、ナビゲーション、リファクタリング、テスト、デバッグは、JetBrains IDEのワークフローにおいて今も欠かせない要素です。役立つ場面ではエージェントを使い、自分でコードを書き、あるいは同じIDE内で両方を組み合わせることができます。私たちのビジョンについて詳しくはこちら。
Start with the language or framework that drives most of the project. The selector shows all of the JetBrains IDEs that support a selected language, so you can then compare their support for the other technologies you use.
はい。JetBrains AIに含まれるエージェントを使用したり、ACP対応エージェントを接続したり、独自のプロバイダーとAPIキーを持ち込んだり、ローカルモデルを構成したりできます。利用可能なオプションは、IDEやバージョンによって異なる場合があります。
It gives the agent deterministic tools for intelligent search, deep analysis, and structure-aware changes. This helps it find relevant code and make project-wide changes using the IDE's code model, not just grepping, consuming fewer tokens.
If AI features are not installed or enabled, they do not have access to your code. With cloud-based AI, the prompt and project context needed to process it go to the selected model provider. With a local model, requests are handled by your local runtime. JetBrains doesn't persist customer data unless you opt in to detailed data collection, which is off by default.
はい。IntelliJ IDEAとPyCharmには無料のコア機能があり、商用・非商用のプロジェクトで利用できます。CLion、DataGrip、Rider、ReSharper、RubyMine、RustRover、WebStormは非商用利用が無料です。すべてのIDEに30日間の無料トライアルも付いています。
Air is JetBrains' system for building software with agents – in your IDE, in the browser, or from the CLI. It works with the agents you already use, including Claude, Codex, and Gemini, plus any ACP-compatible agent, and adds shared team workflows and governance for organizations scaling AI adoption.
