Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the core workflow, and it saves real time caught me off guard. still, I'd recommend giving it a real trial.

Use it every day

Honestly didn't expect to like it this much. The dashboard is exactly what I needed, and it saves real time. I do wish the docs could be deeper, but I reach for it almost every day now and it just clicks.
