JetBrains AI Assistant

JetBrains AI Assistant is the AI coding platform integrated natively into JetBrains' family of professional IDEs: IntelliJ IDEA, PyCharm, WebStorm, GoLand, RubyMine, PhpStorm, CLion, Rider, and others, as well as Android Studio and Visual Studio Code. Built on 25 years of JetBrains code intelligence engineering, the AI Assistant uses the same indexing, type inference, refactoring engine, and code analysis that has powered IntelliJ IDEA since 2000, grounding AI suggestions in deep codebase understanding rather than text-based context alone. JetBrains reports that 91% of AI Assistant users saved time, 80% saved up to 5 hours of development work per week, and 77% reported an improved developer experience. Junie is JetBrains' autonomous coding agent, handling multi-step tasks within the IDE: code refactoring, test generation, feature implementation, and bug fixing with the developer reviewing and approving each step. The platform supports multiple frontier LLM providers: Google Vertex AI, OpenAI, Anthropic Claude, and Google Gemini are all available as model backends, with BYOK supported on Enterprise for organizations supplying their own API keys. JetBrains' own Mellum model provides specialized coding capabilities, and Mellum2, a 12B parameter model open-sourced in Q2 2026, is designed for routing, Q&A, sub-agents, and private AI deployment in software engineering systems. Integration depth is the strongest in the AI coding category. JetBrains AI runs natively inside 9+ IDEs plus Android Studio and VS Code, with deep access to project structure, type inference, and refactoring capabilities that context-window-only tools cannot match. GitHub, GitLab, and Docker integrations are built in. MCP support enables external tool connections, with company-wide MCP policies available on Enterprise for governance at scale. Koog 1.0, JetBrains' AI agent framework for Kotlin and Java released in Q2 2026, provides a stable core with a 1-year API stability guarantee for teams building production agent backends. Pricing covers four tiers using AI Credits as the billing unit. AI Free is included with JetBrains IDEs and provides 3 AI Credits per 30 days for baseline AI features. AI Pro at $100/year per user provides 10 AI Credits per 30 days with expanded AI capabilities, chat, code generation, and access to frontier models, with anytime credit top-ups available. AI Ultimate at $300/year per user provides 35 AI Credits per 30 days for frequent coding agent use with anytime top-ups. AI Pro is also bundled in the All Products Pack at $299/year individual, which includes all JetBrains IDEs, extensions, and profilers. Enterprise AI at $60/user/month ($720/user/year) billed annually, part of JetBrains IDE Services, adds the maximum AI credit allocation, on-premises or cloud or hybrid deployment, BYOK, SSO and SCIM provisioning, AI audit logs, zero data retention, company-wide MCP policies, and usage analytics dashboards. JetBrains AI is not the right fit for developers who do not use JetBrains IDEs as their primary environment. VS Code users who want native agentic coding without switching editors should evaluate Cline (free BYOK) or GitHub Copilot at $10/month. Developers who want fully autonomous task execution without per-step review should evaluate Devin at $20/month or Claude Code. The pricing model is also more complex than single-tier subscriptions: AI Free, AI Pro, AI Ultimate, AI Pro in bundles, and Enterprise all carry different price points and feature sets, creating evaluation friction that Cursor at $20/month flat or GitHub Copilot at $10/month do not have. Current state Q2 2026: JetBrains open-sourced Mellum2, a 12B parameter model engineered for routing, Q&A, sub-agents, and private AI deployment in software engineering systems. Koog 1.0, the AI agent framework for Kotlin and Java, reached stable release with a 1-year API stability guarantee. JetBrains AI Assistant continues to expand across Android Studio and VS Code in addition to all JetBrains IDEs. Company-wide MCP policies and usage analytics dashboards are available on the Enterprise tier. JetBrains holds SOC 2 Type II certification. JetBrains is privately held by founders and team members, funding R&D from operating cash flow without venture capital involvement.
