Good value, works well
Really solid tool overall. The recent updates have addressed most of my initial concerns. The AI doesn't just suggest — it learns from my preferences over time. The customization options let me tailor it to my exact workflow. My only complaint is the pricing could be more competitive. Best tool in this category, hands down.
