Be specific about your content: instead of "coffee" try "a flat white in a ceramic cup at sunrise, minimalist cafe setting". Include the mood you want to convey, your brand voice, and any specific call to action. The AI produces better results with more context. You can also specify the platform (Instagram vs LinkedIn) as content styles differ significantly between platforms.
Yes — content generated by these tools can be used commercially. You own the output. However, AI-generated content should be reviewed and edited before publication.
