I often find getting started to be one of the hardest things about writing. Rytr has already helped me overcome that for sales emails and blog articles because you give it a few lines and it comes back with 3 variations of content to get you started.

The quality of text is great - native speaker level.

The only niggle is that it charges by characters and you have no way of knowing how many character any given request is going to take up. There should at least be an indication in the product of how much a request is going to cost, or else a different way of pricing (e.g. per request rather than the returned characters).

Nevertheless, I wouldn't let this stop me from buying. Rytr is a great tool.
