Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the integrations, and the value for money is strong 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 onboarding is exactly what I needed, and it is genuinely easy to set up. I do wish the docs could be deeper, but I reach for it almost every day now and it just clicks.

Compared a few options

Evaluated this against two competitors. Where it wins: the onboarding and it saves real time. Where it lags: pricing gets steep at scale. On balance the feature set — especially the core workflow — justifies the 5 stars for our use case.
