Worth every cent
This is exactly what I was looking for. The interface is intuitive enough that I didn't need to read any docs. The ROI was clear within the first week of using it. Best tool in this category, hands down.

Good value, works well
Really solid tool overall. It integrates well with VS Code / Slack / Notion — my daily drivers. My only complaint is the pricing could be more competitive.
