Imagine you need to create a creative description for the 50th decorative product today. At one point it becomes extremely draining to come up with new words. We first tried an outsourcing agency, which let us wait for 6 weeks to deliver 400 descriptions. We delayed our product launches and the results were a disaster, and the time was wasted.

The quality of the output tends to be better than other AI Assistants, mainly because you can control the creativity of the AI. For example, setting a low score allows writing better articles when you need research and data. In those cases, and in my experience, this tool does not need as much fact-checking as others (note that I said "as much"), including Jarvis, the gold standard that, sometimes, tends to be too creative and makes up stories and data. TextCortex is good for long-form articles, and you will have usable input as raw material for your content.

I own multiple businesses so Text Cortex can be used for all of my businesses. From blog posts to product descriptions and marketing copy. It's a great tool when you're in need of ideas.
