Picked this up a while back and it's earned its spot in my toolkit. I mainly use it for blog content and the SERP analysis is the part I keep coming back to — seeing what terms competitors actually rank for takes a lot of the guesswork out of writing. Took me a day or two to figure out the workflow but once it clicked I was way faster. Not perfect (longer docs can lag - but just a little bit), but for the price I paid I'm not complaining one bit.
