Really good — a few things to improve
Very good, with a few rough edges. The interface is intuitive enough that I didn't need to read any docs. I use this daily and it's become essential to how I work. The free tier is genuinely generous compared to competitors. A few missing integrations I'd like to see added. Highly recommend.
