Game changer. Stays on topic, generates solid layouts, fast, and switching formats is smoother than I expected, so what else do you really want/need? Big plus that it lets you test things properly before hitting you with a paywall (most tools do exactly that). Giving this one a 5 for sure!

I had to tweak a few things to match my brand style, but overall it saved me a ton of time. Definitely handy if you need something fast and professional-looking.
