JetBrains AI Assistant Overview
If you're already a JetBrains IDE user, AI Pro at $8/month is a no-brainer. The deep IDE integration eliminates context-switching, and the shared credit system with Junie/Claude Agent is clever. AI Ultimate at $30/month is pricey compared to Copilot's $10, but the frontier model access (GPT-5, Claude 4.5) justifies it for power users. The 2.3 marketplace rating reflects performance concerns-be prepared for occasional lag.
