Is just one of the worse apps that I have tried in the last years... If the cat eats the mouse, your story/image will not be created because it will be censored... It's completely useless for a professional use, only good to play things like "Create the image of a train", but never play fantasy or fantastic stories asking to "Create the image of a train, jumping and diving into the sea." See the Data safe section above and verify how unsafe it is using it.

Been having a horrible experience with Stackwares. I paid $100 and Rae AI still cuts me off for "daily limit" when I paid $100 for lifetime, and I paid for a year access on THIS app, which also nags me about a daily limit (apparently like 10 min?). Directly after restoring purchase successfully from my Google act. I have paid $150 between 2 different apps from the same dev, and neither work! I have never ever in my life gotten service for anything that was this bad. And they never replied to me.

Hi Ryan, I’m really sorry for the experience—that’s not what we want at all. Your purchase is valid, and we’ll make this right. Please email us at [email protected] so we can review your account and adjust the daily limit to what works best for you. Thanks for your patience 🙏

well since there's no way to upload files in the writing assistant... and in looking to see if there's a "trick" your Frequently asked questions link won't open, you have no support bot, your LLM in the writing assistant section (Claude) has no idea what features the platform has. you get 1 star.... only reason it's that high is it's required to post this review. your title is misleading, I could overlook that *IF the app was good and worked. but it doesn't.. I'll be cancelling pro membership
