JetBrains AI Assistant is the AI layer built into JetBrains IDEs: IntelliJ IDEA, PyCharm, WebStorm, GoLand, PhpStorm, RubyMine, CLion, Rider, RustRover, DataGrip and DataSpell. It is also available in Android Studio and in ReSharper for Visual Studio, and a public preview extension brings it to Visual Studio Code. It covers code completion and next edit suggestions, an AI chat, and in-editor actions that explain code, suggest refactorings, find problems, and generate tests, documentation, commit messages and pull request descriptions. Code completion runs on Mellum, JetBrains' own model trained for coding, and does not use AI Credits. The AI chat hosts several coding agents. Junie is JetBrains' own agent: it plans multi-step tasks, works across files, can drive the debugger, and lets the developer review and approve key actions as it works. Junie also runs from the terminal as Junie CLI, from GitHub issues and pull requests, and in GitLab CI/CD. Claude Agent, OpenAI Codex and GitHub Copilot are integrated agents in the same chat, and since June 2026 Codex has been the recommended default agent. Any agent that supports the Agent Client Protocol (ACP), such as Gemini CLI, can be installed from the ACP Agent Registry without a JetBrains AI subscription. MCP works in both directions: the AI chat connects to external MCP servers, and since version 2025.2 JetBrains IDEs include an MCP server that external clients such as Claude Code and VS Code can use to analyze code, modify files and run configurations. Through JetBrains AI the chat offers cloud models from OpenAI, Anthropic, Google and xAI, and developers can instead bring their own OpenAI or Anthropic keys or connect local models through Ollama or LM Studio. Pricing is in USD and is set per user. AI Free is included with JetBrains IDE licenses and carries 3 AI Credits per 30 days. For individuals, AI Pro is $100 per year or $10 per month with 10 AI Credits per 30 days, and AI Ultimate is $300 per year or $30 per month with 35 AI Credits. Organization licenses are $200 per year or $20 per month for AI Pro with 20 AI Credits, and $600 per year or $60 per month for AI Ultimate with 70 AI Credits, and organization AI Pro carries a 50% discount for startups. AI Enterprise, part of JetBrains IDE Services, is $60 per user per month billed annually ($720 per year) and is sold through a demo request. AI Pro is also included in the All Products Pack and dotUltimate, at $299 and $219 for the first year for individuals. One AI Credit is worth USD 1.00, top-up credits stay valid for 12 months, and a 30-day AI Pro trial starts when JetBrains AI is first activated. AI Free is not available in IntelliJ IDEA without an Ultimate subscription, in PyCharm without a Pro subscription, or in Android Studio, where AI Pro is the entry point, and it does not include next edit suggestions. When the included credits run out, cloud AI features pause until the quota renews after 30 days or credits are topped up, and unused included credits do not roll over. On-premises LLMs, organization-wide provider keys, SSO and SCIM, AI audit logs and on-premises or hybrid deployment are AI Enterprise features. Junie in the IDE is available in IntelliJ IDEA Ultimate, PyCharm with a Pro subscription, WebStorm, GoLand, PhpStorm, Rider, RubyMine and RustRover, and the GitHub Copilot agent needs its own GitHub Copilot subscription. JetBrains AI Assistant suits developers and teams who work in JetBrains IDEs and want AI features and a choice of coding agents inside that environment. Developers who want an AI-first editor built around the agent should consider Cursor, developers who want one assistant across many editors and inside GitHub's pull request workflow should consider GitHub Copilot, and developers who want an agent that runs from the terminal on a Claude subscription should consider Claude Code. Current state Q3 2026: on September 22, 2026 JetBrains introduced JetBrains Air, a system of products for agent-driven development made up of Air in JetBrains IDEs, Air Teams and Air Governance (formerly JetBrains Central), and said Junie will be supported across all Air surfaces. The 2026.2 IDE releases made GitHub Copilot a natively integrated agent. In June 2026 JetBrains open-sourced Mellum2, a 12B-parameter model, under the Apache 2.0 license. The JetBrains AI terms state that JetBrains will not use customer inputs, data or outputs to train models unless the customer expressly agrees, and detailed data sharing is off by default on paid licenses and on by default, with an opt-out, on non-commercial licenses. JetBrains publishes SOC 2 Type II reports covering JetBrains AI and Junie and a GDPR audit report summary, and its privacy notice includes a section for California residents under the CCPA.
