JetBrains AI Assistant is an AI-powered coding companion that integrates directly into every JetBrains IDE, providing context-aware code generation, intelligent completion, and natural language interaction within the development environment. It solves the problem of incorporating AI assistance into established development workflows by embedding intelligent features natively into the IDE rather than requiring developers to switch to external tools or different editors. The AI Assistant leverages the deep code understanding that JetBrains IDEs already possess to deliver more accurate and contextually relevant AI suggestions.
JetBrains AI Assistant supports multi-file editing through chat, using retrieval-augmented generation (RAG) to locate the most relevant files in your project and suggest changes across multiple files simultaneously. Key features include the /web command for fetching documentation directly in chat, Model Context Protocol (MCP) support for connecting to external data sources, image attachment analysis for debugging from screenshots, and advanced context understanding that includes recently accessed files. The assistant supports models from multiple providers and offers flexible model selection, allowing developers to use OpenAI, Anthropic, or Google models depending on their preference and task requirements.
JetBrains AI Assistant is designed for professional developers who are already invested in the JetBrains IDE ecosystem and want to add AI capabilities without changing their editor. It is particularly valuable for Java, Kotlin, Python, and web developers who benefit from the deep language understanding that JetBrains IDEs provide as context for AI interactions. The AI Free tier offers unlimited local completions and limited cloud credits. Personal AI Pro is listed at $8.33/month on annual billing or $10 month-to-month, while commercial AI Pro is higher; AI Ultimate adds more credits and features at a materially higher price. Enterprise plans provide organizational controls, compliance features, and centralized billing.
