💬 User Reviews

“If you're already a JetBrains IDE user, AI Pro at $8/month is a no-brainer. The deep IDE integration eliminates context-switching.”

“Usage of local models and code completion powered by JetBrains' Mellum model does not consume your AI quota. Great value.”

JetBrains FAQ2026-01-15

“Good for IntelliJ users but I prefer Cursor's more flexible approach. JetBrains AI feels locked in.”
