Windsurf
Windsurf is the world's first agentic IDE featuring Cascade, an AI agent that combines deep codebase understanding with real-time awareness of your actions to enable autonomous, collaborative coding workflows.

JetBrains AI Assistant is an integrated AI coding companion built specifically for JetBrains' suite of IDEs, including IntelliJ IDEA, PyCharm, PhpStorm, ReSharper, and other development environments. The assistant provides intelligent code suggestions, automatic documentation generation, code explanations, test generation, and help with commit messages, all seamlessly integrated into the IDE experience developers already know. The platform offers access to leading AI models including Claude 3.7 Sonnet, Google Gemini 2.5 Pro, and the latest OpenAI models, with a free tier providing unlimited code completion, access to local AI models, and a small cloud credit quota. JetBrains introduced Junie, an agentic AI that can handle planning, writing, refining, and testing code autonomously within the IDE environment. JetBrains AI Assistant uses a credit-based system where each AI Credit equals $1 USD, and the number of credits available matches the subscription price – the AI Pro plan at $10/month provides 10 credits, while AI Ultimate at $20/month provides 20 credits. The AI Pro plan is included in the All Products Pack subscription at $28.90/month, making it an attractive option for teams already using JetBrains tools. However, the AI Assistant has faced significant criticism in 2025, with users rating it only 2.3 out of 5 stars on the JetBrains Marketplace based on 851 ratings. Common complaints include performance issues, latency, integration concerns, and controversy over the removal of negative reviews. Despite over 22 million downloads, the tool continues to receive mixed feedback, though JetBrains is actively improving it with regular updates and expanded capabilities.
